- 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.
