- LightDM Overhaul: Rewrote `install_lightdm()` logic to verify both lightdm and lightdm-gtk-gtk-greeter-settings. Now installs the trio in a single command if missing, skipping only when fully present. Added "Enable autologin" option modifying `/etc/lightdm/lightdm.conf` with robust `sed` patterns for `SUDO_USER`. Fixed missing `debconf-set-selections` to ensure LightDM is set as default during installation.
- GDM3 Implementation: Created a new sub-menu in `modules/desktop_display.sh` allowing independent installation of GDM3, User List toggle (hide/show), Autologin configuration via `/etc/gdm3/daemon.conf`, and conditional "Force Enable Wayland on NVIDIA" for Debian 12/13 using udev symlinks.
- SDDM Integration: Added SDDM as option 3 in the Display Manager menu. Implemented automatic session detection (Wayland > X11) to populate `/etc/sddm.conf.d/autologin.conf` without user input, defaulting to plasmawayland, lxqt-wayland, or generic fallbacks.
- greetd support: Added conditional support for Debian 12 and 13 only. Implemented sub-menu with base install, recommended `tuigreet` (with backports handling for Bookworm), and other manual setup options (`gtkgreet`, `nwg-hello`, `wlgreet`) exclusive to Trixie.
- ZRAM UX Improvements: Updated descriptions in `modules/zram.sh` to explicitly mention I/O reduction and responsiveness benefits for low-RAM systems (e.g., 4GB). Cleaned up compression algorithm labels (`lz4`, `zstd`) to remove redundancy in menu values.
- General Code Quality: Standardized all user-facing messages to English across modules. Ensured independent package installation checks prevent script abortion if one DM fails, while maintaining strict error handling for system configurations.
- update docs and readme
- Removed dead Broadcom hardware IDs (4357/4358/4360/4727) from `_is_broadcom_b43`, retaining only valid ID 4352 to eliminate false positives in the case statement.
- Added a guard in `_handle_wireless` Level 3 to verify `linux-headers` availability via `apt-cache policy`. Skips DKMS compilation if headers are missing, preventing transaction failures during installation.
- Implemented Broadcom combo card detection (WiFi + Bluetooth) by scanning `PCI_BT_DEVS`. Automatically writes `/etc/modprobe.d/broadcom-combo.conf` with `softdep wl post: btusb` and warns users about potential reboot requirements.
- Enhanced Level 2 (`firmware-b43-installer`) with post-installation validation for `/lib/firmware/b43`. Provides clear recovery instructions via `sudo dpkg-reconfigure firmware-b43-installer` if the directory is empty or missing after installation.
- Created a new helper `_msg_red()` in `utils.sh` to handle critical error messages with colored Whiptail output, replacing standard alerts for migration warnings and failures.
- Updated `repos/migrate.sh` to use `_msg_red()` for branch migration warnings and failure states, ensuring visibility of critical issues while keeping completion messages informative.
- Verified headless mode guards across 16 separate extras files (`office.sh`, `fetch.sh`, `cursors.sh`, etc.), preventing unnecessary package installations on servers without display environments.
- Completed syntax verification (`bash -n`) across all core and extra modules, ensuring no errors in the updated logic for firmware, gaming, swap, or repository management scripts.
- update readme.md
- Fixed script crashes from `whiptail` Cancel/Esc under `set -e`. Added `_menu()`, `_checklist()` and `_inputbox()` wrappers with `|| true` to prevent premature exits.
- Resolved startup failures by using defaults instead of relying on unset variables with `set -u`.
- Hardened sudoers management — `_validate_sudoers()` writes to temp file, validates with `visudo -cf`, only copies if successful.
- Replaced `eval` in `_run_cmd` with safer `bash -c` execution.
Swap Management Module (`modules/swap.sh`)
- New standalone module with 9 internal functions and `manage_swap()` entry point.
- Btrfs CoW detection — applies `chattr +C` before swapfile creation to prevent mkswap rejection on Btrfs.
- Dynamic swappiness configuration — reads current system value instead of hardcoding 60, pre-fills inputbox with existing setting.
- Uses `/run/lock/debianito-swap.lock` for early init compatibility (added as option 9 in main menu).
Repository & Branch Migration (`modules/repos/migrate.sh`)
- Handles branch migration from stable (11/12) to Testing or SID with 5-screen UX flow.
- Persistent backup system — creates timestamped tar.gz backups of `/etc/apt/sources.list*`, auto-restores on apt update failure.
- SID guardrails — installs `apt-listbugs` and `apt-listchanges` before upgrade to warn about critical bugs in unstable packages.
- Dynamic menu options based on Debian version (SID shows only 1-2-3 Exit, non-SID includes backports + branch migration).
- New `_components_enabled()` helper detects current contrib/non-free state.
Gaming Module Overhaul
- Unified gaming checklist — merged i386 toggle into single prompt with lazy evaluation instead of separate pre-check.
- Lazy 32-bit architecture enablement — only enables i386 when needed (steam/lutris/i386 selected) and installs graphics drivers if `need_32bit=true`.
- New `_install_nvidia_32bit()` helper with proper driver detection, version pinning, and legacy/tesla variant handling.
Heroic & OpenRGB Downloads
- Heroic — fetches latest release from GitHub API using `jq` to extract amd64.deb URL, validates with `dpkg-deb --info`.
- OpenRGB — downloads from Codeberg Gitea API with SHA256 verification when available, fallback to `dpkg-deb` validation.
- Dynamic codename detection — now detects Bookworm vs Trixie at runtime instead of hardcoded static values for .deb download URLs.
|Other Improvements
- Renumbered main menu: 8=ZRAM, 9=Swap Management, 10=Extras, 11=Boot Rescue, 12=Exit.
- Improved `detect_storage()` — excludes loop/CD-ROM devices via `lsblk -e 7,11`, explicitly skips zram, detects USB/SD via `/sys/block/$name/removable`.
- Standardized SCROLL_HINT across all files with centralized readonly variable.
- System Time (NTP)*: Overhauled `modules/utils.sh`. `check_system_time()` now warns if year < 2025 and enables NTP silently if off but valid. `sync_system_time()` conditionally installs/starts `systemd-timesyncd` and verifies synchronization via `timedatectl NTPSynchronized`.
- LightDM Configuration: Added `_configure_lightdm()` to ensure the user list is visible in the greeter. Installs `lightdm-gtk-greeter-settings` and creates an override config (`99-show-users.conf`) during startup without interrupting the flow.
- Wine Installation: Simplified Wine setup in `system.sh` and Bullseye `extras.sh`. Removed i386 multiarch logic; now installs only `wine64 fonts-wine`. Added post-install version verification to confirm successful deployment.
- Lutris Dependencies: Updated `install_lutris()` in `tools.sh` and `legacy.sh`. Now conditionally adds `wine32` only if the system supports i386 architectures, preventing dependency failures on 64-bit-only setups.
- Boot Rescue Module: Created new standalone `modules/rescue.sh`. Provides UEFI boot repair tools: Secure Boot refirm (shim + GRUB) and Initramfs regeneration for all kernels. Integrated into the main menu as a dedicated rescue section.
- update docs

- Updated `_run_cmd` to integrate the new pause logic for consistent workflow interruptions during script execution.
- Added `_detect_lang()` helper to `modules/utils.sh` (extracts first 2 chars from `$LANG`, fallback to `en`).
- Created `_detect_lang_pkg()` utility for LibreOffice localization: handles regional variants (`es-ar` → `es`) and skips English packages.
- Implemented `_check_network()` with cascade methods (ping→wget→curl) in `modules/utils.sh`. Warning-only pre-flight check after `check_sudo` in `debianito.sh`, compatible with `set -euo pipefail`.
- Fixed system time validation: changed `2026` threshold to `2025` in `check_system_time()` (replaced self-referential `$(date +%Y)` which always evaluated false).
- Refactored LibreOffice language selection in `office.sh`: replaced 10 lines of inline logic with `_detect_lang_pkg "libreoffice-l10n"`.
- Overhauled Firefox ESR integration in `internet.sh`: added state detection, mutual exclusion guard (both Firefox variants selected → warning), new `install_firefox_esr()` function with language support.
- Updated `install_firefox_mozilla()`: added Debian version guard (`<12`), replaced `_run_install` with `_run_cmd`.

- Pascal GPU Detection: Expanded 5 ID blocks (`0x15F0 – 0x1D7F`, 528 IDs total). Added support for TITAN Xp, GTX 1080 Ti, and Quadro P-series. Unified GP106/107 ranges and bounded end at `0x1D7F` to prevent Turing conflicts.
- Validation: Passed `bash -n` checks on all modified files. Confirmed zero ID collisions between Maxwell, Fermi, Kepler, and Pascal architectures.
- 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/
- NVIDIA CUDA extrepo refactor in `modules/gpu/nvidia.sh`: removed unnecessary `i386_active` lines, updated warning to reference `v590 (unified metapackage)`, simplified installation from 18+10 versioned packages → `nvidia-driver-pinning-590 nvidia-driver firmware-nvidia-gsp`, eliminated `apt-mark hold` since pinning packages now handle it. DKMS verification and `NVIDIA_DRIVER_MODE="cuda-repo"` preserved.
- CUDA repo case fix in `modules/gaming.sh`: replaced silent bypass with detection of `nvidia-driver-libs:i386` v590 installation; if missing, prompts user confirmation before installing via active CUDA repo + pinning.
- Palemoon internet module overhaul (`modules/extras/internet/internet.sh`): removed deprecated `_enable_palemoon_repo()`, created new `install_palemoon()` with AVX2→AVX→SSE2 CPU detection from `/proc/cpuinfo`, proper `extrepo enable` call, and package installation.
