- 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
- 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
- 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`.
- Standardized header in internet menu and improved whiptail UX for Firefox options.
- 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.
- ProtonVPN module rewrite (`modules/extras/internet/internet.sh`): removed broken `_enable_protonvpn_repo()` that failed due to missing suite; created new `install_protonvpn()` using `stable` suite + `proton-vpn-gtk-app` package with proper validation.
- Java/Minecraft rename across `modules/gaming.sh` and `modules/extras/java.sh`: renamed `_install_gaming_java()` → `install_minecraft_java()`, updated menu title from "Java Runtimes for Gaming" to "Java Runtimes for Minecraft", changed whiptail tag from `"java-jre"` to `"java"`.
- RetroArch + 4 classic cores (`modules/gaming/tools.sh` and `.sh`): added RetroArch entry to gaming menu, new case handler in `gaming.sh`, updated installation command to include `libretro-mgba libretro-snes9x libretro-nestopia libretro-gambatte`, enhanced notice with emojis, core enumeration, DFSG warning, and wiki link.
- OnlyOffice server status (`modules/extras/office/office.sh`): added fallback message for slow or down OnlyOffice servers to improve user experience during installation.
- Full syntax validation: all modified files pass `bash -n` without errors; no residual references to old variables (`i386_active`, `590.48.01`) or functions remain.
- Documentation about Debian and the script is added to supplement important information.
- update README.md
