- `.github/workflows/ci.yml` added as a new workflow: job `lint-and-test` on `runs-on: ubuntu-latest` with `container: debian:trixie`, checking out via `actions/checkout@v4`, installing `bats` and `shellcheck`, running `shellcheck --severity=error debianito.sh modules/**/*.sh` (with `shopt -s globstar`) and `bats tests/`.
- `debianito.sh` CLI parser: `AUTO_YES=0`, `ALLOW_DESTRUCTIVE=0` declared after `MODULES_DIR` and before `_boot_mark`; `_usage()` prints `Usage: debianito.sh [OPTIONS]` with `--yes`, `--allow-destructive` and `--help`; the `while [ $# -gt 0 ]` / `case` loop consumes `--yes` and `--allow-destructive`, prints `Unknown option: $1 (run with --help for usage)` to stderr and `exit 2` for unknown flags, and `--help|-h` runs `_usage` then `exit 0`.
- `modules/utils.sh`: new global `_SELECTION_CONFIRMED=0` and `_confirm_install_list()` (utils.sh:756-785), which renders items capped at 15 with `... and N more`, computes `height` capped at 24, calls `_confirm "$title" "$list" "$height" 65`, arms `_SELECTION_CONFIRMED=${#items[@]}` on yes, and returns 1 for an empty list or on decline. `_install_pkg()` (utils.sh:789-804) decrements the countdown instead of prompting, and only prompts via `elif ! _confirm "Install: ${pkg}" "Install ${pkg}\nVersion: ${ver}?"; then return 0`.
- Bulk retrofit in `modules/extras/**/*.sh` (18 sites): `_confirm_install_list "Título" "${array[@]}" || return` placed right after the `whiptail` selection is parsed, the install loop left intact, and `_SELECTION_CONFIRMED=0` after the loop. Files: office/office.sh:101, system/software_centers.sh:29, system/system.sh:133, communication/communication.sh:68, design/design.sh:42, download/download.sh:48+55, terminals/terminals.sh:31, security/security.sh:30, players/players.sh:20, themes/fonts/fonts.sh:32, dev/dev.sh:44, programming/programming.sh:57, themes/desktop-themes/desktop-themes.sh:30, fetch/fetch.sh:41, themes/icons/icons.sh:47, themes/cursors/cursors.sh:28, internet/internet.sh:197, java.
- `modules/bullseye/extras.sh` (13 sites) plus `modules/bullseye/legacy.sh` (1 site, `install_gaming_bullseye`, guarded with `if [ ${#_install_pkgs[@]} -gt 0 ]` so a i386-only selection does not blank the summary) plus `modules/desktop_display.sh` (1 site, XFCE Custom — a no-loop `_run_cmd` batch with the reset immediately after it). Special cases: download.sh and bullseye/download each have two checklists merged into one combined summary; legacy.sh gaming skips the reset when the list is empty; XFCE Custom resets before `_xfce_polkit_rules` so the counter cannot leak.
- `modules/desktops/desktop_gnome.sh` (new): `gnome_menu()` runs a `_radiolist` with "1" "GNOME (Full Desktop)", "2" "GNOME Core (Minimal Install)", "3" "Back", then `_install_gnome_full()` and `_install_gnome_core()`. Each arms `_confirm_install_list "GNOME Full Desktop" gnome gdm3 || return` (core: `gnome-core gdm3`), keeps an already-configured display manager via `_existing_display_manager` by setting `target_dm="$keep_dm"`, writes the preseed `echo "${target_dm} shared/default-x-display-manager select ${target_dm}" | sudo debconf-set-selections`, installs `sudo apt install -y gnome gdm3` / `gnome-core gdm3`, enables `gdm3` only when `target_dm = "gdm3"`, resets `_SELECTION_CONFIRMED=0` and calls `_offer_pipewire_after_desktop`.
- `modules/desktops/desktop_kde.sh` (new): `kde_menu()` runs a `_radiolist` with "1" "KDE Plasma (Full Desktop)", "2" "KDE Plasma Desktop (Minimal)", "3" "Back"; `_install_kde_full()` and `_install_kde_minimal()` arm `_confirm_install_list "KDE Plasma Full" kde-standard sddm || return` (minimal: `kde-plasma-desktop sddm`), preseed `sddm shared/default-x-display-manager select sddm`, install `sudo apt install -y kde-standard sddm` / `kde-plasma-desktop sddm`, enable `sddm` only when it is the target DM, reset the counter and offer PipeWire.
- `modules/desktop_display.sh` `desktop_environment_menu()`: `env_items+=("3" "GNOME")`, `env_items+=("4" "KDE Plasma")`, `env_items+=("5" "Back")`; the case adds `3)` loading `gnome` via `_load_module gnome || continue` and calling `gnome_menu`, and `4)` loading `kde` via `_load_module kde || continue` and calling `kde_menu`; the dead TODO comment was removed.
- PipeWire retrofit in `modules/desktop_display.sh` (6 sites): `_install_lxde_full`, `_install_lxde_core`, `_install_xfce_full`, `_install_xfce_minimal`, `_install_xfce_wayland` and `_install_xfce_custom` each call `_offer_pipewire_after_desktop` after their install block.
- `_offer_pipewire_after_desktop()` and `_existing_display_manager()` added at the end of `modules/desktop_display.sh`: `_offer_pipewire_after_desktop` checks `pipewire-audio` (`pipewire` when `DEBIAN_VERSION = 11`), returns 0 via `is_installed`, otherwise `_confirm "PipeWire Audio" "No PipeWire audio server is installed.\n\nInstall the PipeWire audio stack (recommended)?"` calls `_install_pipewire_standard` and returns 0. `_existing_display_manager` reads `${DM_FILE:-/etc/X11/default-display-manager}`, reads the basename as the DM, and otherwise scans `gdm3 lightdm sddm greetd gdm` with `systemctl is-enabled`, printing nothing when none is found.
- `_ensure_apt_updated` added before the GNOME/KDE `apt install` transactions (4 sites, deduplicated per session); `gnome gdm3` and `kde-standard sddm` are installed alongside even when another display manager is kept as the default.
- Extraction to `modules/desktops/`: `desktop_lxde.sh` (38 lines) and `desktop_xfce.sh` (119 lines) created with the `lxde_menu` / `_install_lxde_full` / `_install_lxde_core` and `xfce_menu` / `_install_xfce_full` / `_install_xfce_minimal` / `_install_xfce_wayland` / `_install_xfce_custom` / `_xfce_polkit_rules` blocks moved verbatim; both carry `# License GPL v3` in their headers.
- `modules/desktop_display.sh` reduced from 542 to 394 lines (−154): lines 55-208 removed, the dispatch (desktop_display.sh:39-46) replaced with `_load_module xfce || continue` / `lxde_menu`, and the file left with `manage_desktop_display`, `desktop_environment_menu`, `display_manager_menu`, `lightdm_config_menu`, `configure_greetd`, `configure_gdm3`, `configure_sddm`, the two shared helpers.
- `modules/utils.sh` `_load_module` map: `xfce)` → `${MODULES_DIR}/desktops/desktop_xfce.sh`, `lxde)` → `${MODULES_DIR}/desktops/desktop_lxde.sh`, `gnome)` → `${MODULES_DIR}/desktops/desktop_gnome.sh`, `kde)` → `${MODULES_DIR}/desktops/desktop_kde.sh`; deps for `xfce`, `lxde`, `gnome` and `kde` are `(desktop_display audio)` and `desktop_display` is `(repos audio)`.
- `modules/desktops/desktop_xfce.sh` `_xfce_polkit_rules()` writes `/etc/polkit-1/rules.d/85-suspend.rules` and `89-backlight.rules` via `sudo tee`, adds the `backlight` group with `groupadd --system` fallback, adds the real login user from `/etc/passwd` to `backlight` and restarts `polkit.service`.
- ES→EN user-facing strings: 14 strings across 4 files — `desktop_display.sh` `lxdе_menu` ("LXDE (Full Desktop)", "LXDE Core (Minimal Install)"), `gpu/nvidia.sh` Kepler legacy-driver notice ("Kepler GPU detected (GKxxx)… Install the legacy driver for Kepler?"), `bullseye/legacy.sh` ("Install NVIDIA driver?", "Skipping NVIDIA driver.", "Installing NVIDIA driver ${gpu_gen}...") and `bullseye/extras.sh` ("firmware-linux-nonfree provides drivers for… Install?").
- ES→EN internal comments: ~35 comments across 9 files — section headers in `_install_nvidia_standard`, `gpu/_helpers.sh` (lines 5, 113), `gpu/nvidia.sh` (lines 8-12, 19-22, 68-70, 167-172, 196, 239-253, 262-263, 275, 291, 336-338, 376), `gpu.sh` (lines 15-17), `bullseye/repos.sh` (line 2), `firmware.sh` (line 235, "--- Load verification ---"), `utils.sh` (lines 129, 132, 153 — timezone Paso 1/2/4) and `utils.sh:546,548`.
- set -e abort fix: `debianito.sh:149` now reads `_system_preferences_menu || true`, consistent with the other dispatch chains (14 of the 15 chains already had the guard); a declined pre-apply summary now leaves the TUI alive instead of terminating the script.
- `docs/desktops_display.md`: 4 hunks — intro now lists GNOME/GNOME Core/KDE Plasma/KDE Plasma Desktop/XFCE/XFCE Wayland/XFCE Custom/LXDE, a new "Modular layout" paragraph describing `modules/desktops/` and lazy loading, Block 1 rewritten into four environments, five new bullets (pre-apply summary, existing-DM preservation, PipeWire offer, stale-lists guard) and a Desktop Environment Packages table.
- `docs/quickstart.md` line 284: Desktop Environment entry expanded to pick from XFCE (full / minimal / Wayland `labwc` on Trixie / custom checklist), LXDE (full / core), GNOME (full / core) or KDE Plasma (full / minimal).
- `_existing_display_manager` now takes the config path via `local dm_file="${DM_FILE:-/etc/X11/default-display-manager}"` so the offline test suite never reads the real system file.
- `tests/test_helper.bash`: added `_mock_systemctl()` for `is-enabled` (units in `MOCK_SYSTEMCTL_ENABLED` report `enabled`, everything else `disabled`), `MOCK_SYSTEMCTL_ENABLED=""`, `WHIPTAIL_CALLS`/`MOCK_WHIPTAIL_OUTPUT`/`MOCK_WHIPTAIL_RC`, `MOCK_DPKG_INSTALLED` and the `systemctl` entry in the mock list and in `mock_reset()`.
- `tests/desktops.bats` created with 16 tests: `_existing_display_manager` (file read, file-preferred over an enabled unit, enabled-unit fallback, candidate order, missing file, nothing configured), `_offer_pipewire_after_desktop` (5 tests: skip-installed, accept-installs, decline-returns-0, Bullseye package name, wrong package name on 11), `_load_module` (4 tests for xfce/lxde/gnome/kde) and an unknown-module case; 17→33 tests total.
- `.github/workflows/ci.yml` shellcheck severity raised from `--severity=error` to `--severity=warning`.
- `debianito.sh`: `RED`, `GREEN`, `YELLOW`, `CYAN` and `NC` plus `AUTO_YES`, `ALLOW_DESTRUCTIVE` and `DEBIAN_CODENAME` are now `export`ed as cross-file globals.
- `modules/utils.sh`: `HAS_NVIDIA`, `DESKTOP_ENV`, `AUDIO_SERVER`, `DEBIAN_VERSION` and the other cross-file globals are `export`ed.
- `modules/extras/system/software_centers.sh` gained a `#!/usr/bin/env bash` shebang.
- `shellcheck` triage (v0.11.0, baseline `--severity=warning` 25 findings → 0): removed two dead-code lines (`headless` in `extras/dev/dev.sh`, orphan `dev_id` in `firmware.sh`); `SC2206` in `extras/dev/essential.sh` fixed by expanding `$comp_pkgs` to `"${comp_pkgs[@]}"`; `SC2010`/`SC2046` (3 sites) replaced `ls … | grep` with `compgen -G "…"`; `SC2155` (2 sites, `gpu.sh` and `rescue.sh`) split command substitutions into separate lines; `SC2166` in `repos.sh` replaced `-o` with `{ … || … }`; `SC2221`/`SC2222` (2 sites, `sysinfo.sh` and `utils.sh`) collapsed the `wl*|wlp*|wlo*|wlan*` alternation to `wl*`; `SC1090` in `extras.sh` gained a justification comment on the disable directive.
- Final verification: `bash -n` on all 15 modified `.sh` files and `set -euo pipefail` at `debianito.sh:3` both intact; `bats tests/` reports 33 ok / 0 failed; invariants `offers 11`, `confirm_install_list 39` and `_SELECTION_CONFIRMED=0 40` hold.
- Verified the repository backup rc in migrate.sh. `_persistent_backup_repos()` now aborts before any destructive step when the tar archive is missing or corrupt, removing the invalid backup itself.
- Verified the restore rc in migrate.sh. `_restore_backup()` now reports failure instead of printing a green "Backup restored" message, and its caller distinguishes a restored backup from a failed restore.
- Made the upgrade phases fail honestly. `apt upgrade` and `apt full-upgrade` now abort with `apt --fix-broken install` + `dpkg --configure -a` instructions instead of reporting "completed successfully" over a partially-upgraded system.
- Made repository source writes atomic. Both writers tee into a `.tmp` file and move into place, and the `/etc/apt/sources.list` removal now happens after the write.
- Corrected the SID warning text in migrate.sh to reflect that security fixes arrive via package uploads rather than a nonexistent sid-security suite.
- Added exit-path cleanup traps for the temp `.deb` files: `trap 'rm -f "$deb_path"' RETURN` in `heroic.sh`and `tools.sh`.
- Tightened Heroic download handling: the API fetch uses `curl -fsS --connect-timeout 10 --max-time 30`, the download uses `curl -fsSL --max-time 300`, and the `.deb` is validated with both `dpkg-deb --info` and `dpkg-deb --contents`; `sudo apt install` is guarded with `if !` before the temporary file is deleted.
- Tightened the OpenRGB install path: the Codeberg API fetch uses `curl -fsS --connect-timeout 10 --max-time 30` and the download `curl -fsSL --max-time 300`, with the same dual `dpkg-deb` integrity check as the Heroic fallback.
- Guarded the OpenRGB post-install side effects: the script now aborts after removing the failed `.deb` if `sudo apt install` returns non-zero, so `modprobe i2c-dev`, `/etc/modules`, the `i2c` group membership, `udevadm`, and the `setcap` step no longer run when the package is absent.
- Fixed command injection in desktop_display.sh by converting word-splitting loops to safe array-based iteration for LightDM/GDM3 configuration and XFCE package installation.
- Added symlink detection guard before repository file operations in repos.sh to prevent TOCTOU attacks during restore_previous_repos().
- Hardened SUDO_USER resolution with awk validation against /etc/passwd to prevent root fallback and ensure real login users are targeted for sudoers configuration.
- Implemented algorithm (lz4/zstd) and size validation before ZRAM configuration writes in zram.sh to reject invalid inputs.
- Protected grep MemTotal read from /proc/meminfo with 2>/dev/null and default assignment under set -u.
- Added || true guards around apt-cache madison pipelines in firmware.sh, kernel.sh, gpu.sh, and utils.sh to prevent pipefail aborts when backports unavailable.
- Wrapped whiptail installation in if/else blocks to allow offline error messages instead of script termination under set -e.
- Fixed grep -c output duplication in swap.sh with proper || true pattern and default variable assignment.
- Replaced unquoted $cleaned loops with array conversion using while read for secure package iteration across gaming, desktop_display, firmware, and kernel modules.
- Anchored sed regex patterns to space-delimited "main" components to prevent mirror URL corruption in sources.list editing.
- Escaped % characters in _msg() function before passing to whiptail to prevent printf format interpretation crashes.
- Consolidated package version helpers into canonical wrappers: _get_pkg_version, _get_installed_version, _get_backports_version for consistent apt/dpkg queries.
- Created _install_if_missing() and _install_pkg() with proper error handling that respects set -e while providing user feedback on installation failures.
- Removed 6 dead code functions (~51 lines): check_system_time, sync_system_time, get_cpu_summary, get_ram_summary, pkg_versions, get_backports_kernel_version.
- Added detect_displayserver and detect_audio_server to refresh_system_state() for complete state refresh when returning from menus.
- Enhanced _on_interrupt() trap handler to kill lingering apt/dpkg child processes and clean /tmp/debianito.* temporary files on Ctrl+C or TERM.
- Improved restore_previous_repos() with manifest-based backup verification (.backed_up_* markers) to prevent destructive repository file deletion.
- Added mktemp usage for secure temporary deb file downloads in nvidia.sh, heroic.sh, and tools.sh to eliminate TOCTOU vulnerabilities in /tmp.
- Fixed Bluetooth USB dongle misclassification as WiFi devices by excluding "bluetooth" strings from USB_WIFI_DEVS detection in firmware.sh.
- Properly utilized the need array for selective package installation in internet.sh instead of hardcoding full package list.
- Corrected fwupdmgr duplicate execution and grep false positives in system.sh with strict pattern matching for available updates.
- update docs and added quickstart guide
- Replaced the restrictive Broadcom firmware installation flow with a persistent, step-by-step process in modules/firmware.sh. Now installs dkms, wireless-tools, and linux-headers-amd64 separately, then applies blacklist configuration, updates initramfs, and loads conflicting modules properly.
- Fixed conky package name across system.sh and bullseye/extras.sh. Changed from "conky" to "conky-all" with corresponding state variable updates for correct installation via apt.
- Corrected broken GRUB sed command in modules/gpu.sh for AMD GCN support. Added grep guard to prevent duplicate parameter insertion and fixed regex pattern for proper cmdline modification.
- Added whiptail pre-flight check in debianito.sh. Auto-installs required TUI dependencies if missing before the main menu, preventing runtime failures.
- Fixed home directory path resolution bug in modules/sudo_config.sh. Replaced eval echo "~$USER" with getent passwd approach for reliable user home detection across SUDO_USER contexts.
- Implemented global lspci output caching across 18+ locations. Single cache population via _init_lspci_cache() before detect_gpu, all subsequent reads use LSPCI_OUTPUT variable to eliminate redundant hardware polling calls.
- Added apt update deduplication helper in modules/utils.sh. _ensure_apt_updated() with APT_UPDATED flag bypasses redundant package list refreshes across extras/, gaming/, firmware/, and desktop_display/ modules while preserving transactional rollback paths in repos.sh.
- Fixed STATE_REFRESHED logic in debianito.sh main_menu case statement. Added STATE_REFRESHED=true to branches 3, 5, 7, 9, 11, 12, and 13 that mutate system state, ensuring refresh_system_state() triggers correctly after configuration changes.
- Removed dead REPOS_CONFIGURED variable from debianito.sh and modules/repos.sh. Variable was written but never read, eliminated to clean up global namespace without affecting repository functionality.
- Resolved NVIDIA driver management issues by expanding package detection patterns (including nvidia-open and nvidia-kernel-open-dkms), enhancing purge process to ensure clean uninstallation of v590/595 drivers, and adding conditional skip for manage menu when no driver is installed.
- Enhanced Firefox variant selection in internet.sh using exact token matching (grep -qx) instead of substring search to prevent incorrect removal or unintended ESR/Firefox conflicts.
- New XFCE install option with 4 options
- Restructured Desktop Environment into two-level menu system with dispatcher and Xfce sub-menu for scalability, enabling future additions like GNOME/KDE without disrupting existing flows.
- Added Polkit rules in desktop_display.sh to grant suspend permissions without password prompts on laptops, including idempotent group (backlight) creation and user membership management with || true fallbacks.
- Enforced LC_ALL=C LANGUAGE=C environment variables for all dpkg-reconfigure commands across System Preferences and utils.sh to ensure native dialogues run consistently in English.
- Fixed kernel backports menu option availability to only appear on Debian 13, preventing errors on Debian 12 where backports repositories are EOL.
- Improved ZRAM module initialization sequence by ensuring swapoff and zram module removal occur before writing new configuration files to prevent race conditions during system setup.
- Removed redundant confirmation dialogs from `_install_nvidia_stack`. Users can now access driver management (including removal) without first confirming installation intent; initial plan display is followed by pause for review instead of blocking prompt.
- Automated CUDA repository enabling on Debian 13/Bookworm paths (590/595). Manual confirmation prompts eliminated; script auto-enables repo via `_enable_cuda_repo` with error handling while maintaining safety checks.
- Split CUDA driver installation into two distinct APT transactions in `nvidia.sh`. Step 1 installs mandatory version pinning (`nvidia-driver-pinning-${ver}`); failure aborts process. Step 2 installs `nvidia-open`, relying on transitive dependencies for firmware rather than explicit package listing.
- Eliminated all Bookworm backports support due to EOL (2026-08-09). Removed `_install_nvidia_bookworm_bpo()`, dead code `install_nvidia_driver()`, and dispatcher logic for Debian 12. Turing now installs standard packages only; Trixie backports remain intact.
- Updated documentation (`docs/gpu.md`) to reflect actual installation flow and removed references to deprecated functions.
- Refined `_show_nvidia_version_menu` in `modules/gpu/nvidia.sh` for Debian 12/13 with precise labels ("Newest Stable", "Kepler Support") and explicit official repo recommendations.
- Introduced new standalone module `modules/gpu/nvidia_manage.sh` integrated into the dispatcher to handle driver lifecycle management (Install/Change vs Remove) before version selection.
- Implemented safe removal logic (`_nvidia_remove`) with explicit package purging, explicitly excluding `firmware-misc-nonfree`, and cleaning specific configs/repos without wildcards.
- Ensured idempotency across all steps using `|| true` and preserved user CUDA toolkits while restoring Nouveau via initramfs regeneration.
- Fixed critical NVIDIA driver bug on Debian 13 (Trixie) where repo configuration installed v550 instead of selected v595. Implemented version-specific enabling: cuda-keyring for Trixie, extrepo for Bookworm. Added explicit apt update after repo enable and candidate verification before pinning checks to abort cleanly if expected driver unavailable.
- Rewrote `_install_nvidia_standard()` with auto-detected architecture via `_get_nvidia_arch_family()`. Turing/Ampere/Ada/Blackwell → nvidia-open-kernel-dkms (open module); Maxwell/Pascal/Volta/unknown/empty → nvidia-kernel-dkms (closed, safe fallback). Removed all `nvidia-detect` references across modules and docs.
- Fixed `_install_nvidia_cuda_repo()` to use correct CUDA repository package names: v590/v595 → nvidia-open metapackage (includes nvidia-kernel-open-dkms); v550 and below → nvidia-driver. Added dynamic warning message based on installed module type.
- Fixed uninitialized variable bug in `modules/gaming/tools.sh` causing script abortion under `set -u`. Initialized all local variables (`deb_url`, `sha256`, `json`, `deb_suffix`) with default values and added defensive initialization for `$USER` environment variable.
- Fixed ZRAM configuration persistence bug where old config persisted after changes. Added device reset sequence (swapoff + modprobe -r) before writing new config, post-config verification check, and changed default recommendation from 50% to 25% for systems with >16GB RAM.
- Added `_warn_nvidia_gnome_wayland()` function in `gpu.sh` to warn about Debian bug #1109409 (GDM3 + NVIDIA + Wayland black screen issue). Warning displays only when gdm3 present, GNOME Shell 4.x detected, and NVIDIA driver installed.
- Standardized menu headers across all modules using centralized SCROLL_HINT variable, replacing hardcoded strings with uniform Whiptail instructions. Updated documentation for cuda-keyring (Trixie) and ZRAM configuration flow diagrams.
- Refactored NVIDIA installation with robust DKMS verification (`_verify_nvidia_dkms_build`). Automatically detects build failures for the current kernel and repairs them via `dpkg-reconfigure`, ensuring modules compile against active kernels without manual intervention.
- Added Secure Boot detection (`_nvidia_secure_boot_enabled`) to warn users if the NVIDIA module is compiled but unsigned, preventing boot issues on systems with UEFI security enabled.
- Implemented `_configure_nvidia_wayland()` for Wayland support. Detects hybrid laptops (Optimus) vs desktops using DMI chassis types and battery presence. Configures `NVreg_PreserveVideoMemoryAllocations` only for desktops to avoid Optimus conflicts, and adds architecture-specific guards (e.g., Kepler warnings).
- Introduced version selection menu (`_show_nvidia_version_menu`). Users can select driver versions (470/535/550/590/595) based on Debian release. Parametrized CUDA repo installation for 590/595 with post-install DKMS branch verification.
- Fixed state inconsistency bugs in `NVIDIA_DRIVER_MODE`. Added guards to ensure configuration files are only written upon successful installation, preventing partial setups after failures (e.g., backports, CUDA repo).
- Improved hardware detection helpers (`_is_hybrid_laptop`, `_get_nvidia_arch_family`). Prevents false positives on multi-GPU desktops by verifying iGPU presence alongside dGPU.
- Updated Java/Minecraft support in `modules/extras/java.sh`. Added Temurin 25 ("Minecraft 26+") to the runtime selection menu and updated documentation.
- Enhanced utility robustness (`_run_cmd`, `_configure_lightdm`). Properly propagates exit codes from commands and handles failures gracefully (yellow warnings + skip) instead of crashing under `set -e`.
- Normalized PCI ID case sensitivity in `_helpers.sh`. The `detect_nvidia_arch()` function now converts input to uppercase (`${1^^}`) to match legacy architecture map keys, resolving "unknown" detection for all NVIDIA GPUs.
- Removed silent fallback to standard drivers in `gpu.sh` Bookworm logic. Kepler and other architectures now invoke specific installation functions directly without defaulting to unsupported driver versions (e.g., 535).
- Corrected NVIDIA legacy package name in `nvidia.sh`. Updated `_install_nvidia_bookworm_kepler()` to use `nvidia-tesla-470-driver` instead of deprecated Bullseye naming conventions for Debian 12.
- Replaced specific kernel header references (`linux-headers-$(uname -r)`) with meta-package `linux-headers-amd64` in `firmware.sh`. Fixes DKMS installation failures for Broadcom/WiFi drivers across multiple Debian versions.
- Unified PipeWire installation into a single checklist option ("PipeWire Audio Stack"). Removed confusing dual options (Standard/Backports) to streamline Debian 13 workflows. Added Bluetooth Hi-Res codec support (LDAC, aptX, AAC) with automatic detection of `libfdk-aac` variants across all Debian versions.
- Refactored `_install_nvidia_standard()` in `modules/gpu/nvidia.sh` to respect the `NVIDIA_DRIVER_MODE` signal from the dispatcher, eliminating external dependency on `nvidia-detect`. Added logic to select between Open Kernel Modules (Turing/Ada/Ampere) and Classic DKMS (Maxwell/Pascal/Volta). Enhanced confirmation dialogs to display both driver and kernel module versions.
- Updated `_install_mesa_32bit()` in `modules/gaming/_helpers.sh` with the same version resolution and upgrade logic as Audio, ensuring consistent UX for Backports selection on Debian 13.
- Expanded `NVIDIA_FAMILY_MAP` in `modules/gpu/_helpers.sh` to include missing silicon prefixes (Hopper, Blackwell variants) while maintaining "legacy" abstraction for driver policy separation.
- Fixed Mesa 32-bit dependency conflicts by removing mesa-va-drivers from gaming setup; mesa-libgallium now includes VA-API for Mesa >= 25.3.3, resolving solver errors with backports (Mesa 26.x).
- Removed corectrl detection and installation from AMD tools in gpu/amd_intel.sh (retained in System Tools checklist only).
- Added zutty terminal emulator option alongside alacritty for Debian 12+ in terminals.sh.
- Overhauled Kernel menu: replaced "Backports Kernel" with "Kernel" submenu offering Stable, RT, Cloud, and Backports options; removed hardcoded Debian 11 restriction (backports hidden only on Bullseye); headers now installed automatically with all kernel variants; NVIDIA warnings added for Backports (DKMS required) and RT (driver compatibility note).
- Implemented AMD GCN legacy driver migration: is_amd_legacy_gcn() function detects GCN 1.0/1.1 GPUs via whitelist of 85 PCI IDs; offers user prompt to force amdgpu module with GRUB parameters (radeon.si_support=0, radeon.cik_support=0, amdgpu.si_support=1, amdgpu.cik_support=1); safe sed-based injection into GRUB_CMDLINE_LINUX_DEFAULT with backup and idempotency check.
- Standardized UI across 27 checklist locations: unified text to "Check [*] the packages you want installed/updated on your system."; removed SCROLL_HINT variable entirely from all code; changed OK button to "Apply" in _checklist() and _inputbox() only (not in _msg/_menu).
- Reordered gaming menu checklists: i386 moved to top position, steam/mangohud positioned immediately after for better dependency flow.
- Enhanced kernel installation prompts: all variants (Stable, RT, Cloud, Backports) now display candidate version numbers in parentheses using apt-cache policy and madison queries.
- update readme
- Refactored `install_zram` into a dedicated submenu (`zram_menu`) within `modules/zram.sh`. Split monolithic logic into three distinct operations: `_zram_view`, `_zram_create`, and `_zram_remove`. Enables status verification before installation and safe cleanup. Updated main menu entry in `debianito.sh` to call the new sub-menu.
- Resolved Trixie backports dependency conflicts between `mesa-libgallium` and `mesa-va-drivers` (Mesa 26+). Modified package lists in `_helpers.sh` and `gpu.sh` to exclude `mesa-va-drivers` during backports installs, prioritizing `mesa-vulkan-drivers` for stable Gallium integration.
- Implemented dynamic dimensioning in `_show_sysinfo()`. Calculates optimal width/height based on terminal size (`tput cols`) and content length. Truncates long lines to prevent UI overflow in small terminals, capped at 22-line height.
- Bug Fixes: Rewrote `install_gaming_bullseye()` in `modules/bullseye/legacy.sh` to use a unified `_checklist` flow (matching Debian 12/13) with automatic i386 architecture detection and driver installation. Fixed greetd "Back" menu crash on Debian 11 by adding version-specific conditional logic in `desktop_display.sh`. Corrected ZRAM text overflow in `zram.sh` using `\n` line breaks for terminal wrapping. Updated Kernel Backports warning message in `debianito.sh` to clarify Bullseye limitations.
- Architecture & Repositories: Refactored Debian 11 repository configuration (`configure_repos_bullseye`) to reuse modern submenus (`_repos_enable_components`, `_branch_migration`), eliminating ~44 lines of hardcoded logic and duplicate source list management. Restricted `non-free-firmware` component availability to Debian 12+ in `modules/repos.sh`. Implemented mandatory `apt autoremove -y` and `apt autoclean` execution immediately after enabling non-free/contrib components (`_repos_enable_components`).
- UI & Menus: Added a new "Communication" menu (Option 4) between Internet and Media Players, featuring Signal, Telegram (with Trixie backports warning), and Hexchat. Moved all terminal emulators from System Tools to the "Customization System" -> Terminals submenu (`modules/extras/terminals/terminals.sh`) with version-specific logic (Alacritty 12+, Blackbox/Ptyxis 13+). Added Joplin installer in Office & Productivity for Debian 12/13 only. Integrated Synaptic into Software Centers menu alongside GNOME and Plasma stores. Unified Essential Pack UI across versions, switching between `fastfetch` (Trixie) and `neofetch` (Bookworm/Bullseye).
- Hardware Drivers: Replaced deprecated `install_gpu_drivers()` in `modules/gpu.sh` with `_install_amd_intel_stack()` and `_install_nvidia_stack()`. Implemented specific logic for Debian 13 (Trixie): Blackwell GPUs now enable the official NVIDIA CUDA repository; Maxwell/Pascal on Backports forces a stable kernel path to ensure driver compatibility. Deprecated `install_nvidia_driver()` in favor of new stack functions while preserving global state variables (`NVIDIA_DRIVER_MODE`).
- Utilities & Cleanup: Added `gdebi` and `bleachbit` to System Tools (GUI-only). Standardized menu headers across 15 files using a centralized `SCROLL_HINT` variable. Ensured VLC installation is conditional on headless status checks in Essential Pack modules.
- Refined NVIDIA GPU detection in `_helpers.sh`. Corrected Kepler GK208 range (`0x1280–0x12BF`) and added refined Fermi ID ranges to eliminate device collisions across architectures.
- Updated `gpu.sh` driver logic for Debian Bookworm (explicit Fermi veto) and Trixie (unified Kepler/Fermi check). Prevents legacy driver conflicts and ensures correct selection per version.
- Cleaned `bullseye/legacy.sh`. Removed outdated Fermi checks with collisions; now inherits unified validation from `_helpers.sh` to maintain Debian 11 compatibility.
- Fixed Wi-Fi interface regex in `utils.sh`. Added `wlan*` pattern to catch ath9k interfaces (`wlan0`) alongside standard wl/wlp/wlo identifiers.
- Validated syntax across all files with `bash -n`. Confirmed zero collision between Fermi and Kepler device IDs, ensuring stable detection on Debian 11/12/
- Rewrote `modules/firmware.sh` with unified detection and installation flow, reducing user interactions from multiple prompts to single confirmation across all hardware types.
- Enhanced `_detect_all_network_devices()` to scan full PCI device lists without truncation (`head -n1` removed) and filter USB devices by keyword patterns (`wireless`, `wifi`, `802.11`, `bluetooth`, `wlan`) to eliminate false positives from card readers/Realtek audio devices.
- Implemented Broadcom 3-tier firmware strategy: Tier 1 (`brcmsmac`, 8 device IDs) auto-installs without extra confirmation; Tier 2 (`b43`/`b43legacy`, ranges 0x4301–0x4331) requires contrib package warnings; Tier 3 (`broadcom-sta-dkms`) needs DKMS compilation approval with explicit precedence handling for overlapping device ID ranges.
- Streamlined `modules/gpu.sh` flow from 169 to 154 lines, cutting user clicks from 4 (intro → proceed → plan → install) to 2 (plan → install), removing redundant intro message before plan display while preserving Intel/AMD firmware auto-installation and Mesa prompting logic.
- Added Bullseye compatibility hook in `modules/bullseye/extras.sh` (`type _handle_wireless &>/dev/null && _handle_wireless`) to ensure Broadcom wireless handling works correctly in Debian 11 environment with lazy detection fallback for empty PCI network devices.
- Fixed whiptail UI spacing issues in message paragraphs for improved readability and standardized dialog geometry across firmware/graphics dialogs.
- Replaced the fragile upstream script installer with native Deb822 repository injection and automated GPG keyring management in `jellyfin.sh`. Eliminated external dependencies, checksums, and interactive flags for guaranteed non-interactive support across Bullseye/Bookworm/Trixie.
- Upgraded the NVMe module (`modules/extras/system/system.sh`) to perform multi-drive scanning with dynamic `lsblk` parsing. Replaced single-disk detection logic with a `while read` loop to capture all devices, displaying formatted SMART health diagnostics (Critical Warning, Temperature, Percentage Used).
- Overhauled the 'System Information' TUI into a multi-device dashboard featuring standalone GPU/Driver hierarchies and dynamic storage mapping. Added new globals (`DISPLAY_SERVER`, `STORAGE_SUMMARY`) and comprehensive arrays for Network/Wi-Fi interface indexing in `modules/utils.sh`.
- Redesigned the graphics stack layout to fix multi-GPU text clipping and unified Mesa version prompting logic. Integrated post-install package telemetry to display live versions in the completion screen, separating planning visualization from installation decision points in `modules/gpu.sh`.
- Fixed non-free-firmware conceptual documentation bugs and expanded Backports descriptions with hardware-focused educational text. Added non-free repository safeguards for Trixie/Bullseye compatibility under "Firmware & Wireless Drivers".
- Refactored repository logic in modules/repos.sh to eliminate dead code (redundant default_text variables) and strict-hardcoded layout behaviors, standardizing dialog geometry to a clean matrix.
- Updated README.md
- Replaced the restrictive head -n1 hardware parsing with a dynamic while read loop. The script now fully detects and registers multiple coexisting GPUs (Intel+Nvidia / AMD+Nvidia).
- Rewrote install_gpu_drivers() in modules/gpu.sh from a mutually exclusive case block to independent, sequential if conditions. Laptops now install both integrated firmware (Intel/AMD with non-free VA-API acceleration) and dedicated graphics stacks (Nvidia driver + 32-bit libs for Steam) seamlessly in a single pass.
- Improved Nvidia Kepler architecture guards under Debian 13 (Trixie). The script now safely skips missing legacy Nvidia packages without aborting or crashing the remaining Intel/AMD configurations.
- Added nvme-cli utility installation across all Debian versions. For Bookworm and Trixie, it features dynamic hardware validation via lsblk transport filtering and interactive, real-time SMART log viewing with an execution screen-pause.
- Created a brand new standalone module (modules/extras/dev/jellyfin.sh) to cleanly inject Jellyfin Media Server across Debian 11, 12, and 13 using its official setup script, protected by strict SHA256 checksum validations and guaranteed error-cleanup.
- Added OpenRGB to the Gaming menu for Debian 12 and 13. Implemented secure curl downloads with an emulated Chrome User-Agent to bypass Codeberg bot blocks, complete with automatic i2c-dev module configuration, user groups provisioning, and udev permission rules execution.
- Standardized menu headers across 15 separate files using a centralized readonly SCROLL_HINT=" [↑↓]" variable, replacing messy hardcoded strings with clean, uniform Whiptail instructions.
- update README.md
- Created dedicated modules/bullseye/` folder for legacy isolation (Debian 11 support).
- Implemented 4-block inclusive PCI range detection for Nvidia Kepler/Fermi to prevent black screens.
- Centralized system time verification checking against year 2026 before APT execution.
- Cleaned and purged modern package lists for the Bullseye extra software module.
- Updated main menu with conditional sourcing and fixed Option 7 (Gaming Lite) for Bullseye.
- Updated README.md with explicit TUI navigation instructions and full repository directory tree mapping.
