- Created standalone modules/bluetooth.sh for `_install_bluetooth_stack()` with desktop-aware frontend selection (bluedevil/KDE, blueman/XFCE/other). Extracted from `firmware.sh`, reducing it from 438 to 369 lines.
- Added `detect_desktop_environment()` and `detect_audio_server()` functions in `utils.sh` with new globals `DESKTOP_ENV=""` and `AUDIO_SERVER=""`.
- New `found_active_wifi` flag detects Qualcomm Atheros AR9485 PCI chips without loaded firmware, displaying `(no driver — install firmware)` instead of silently disappearing. Auto-installs `firmware-atheros + firmware-linux-nonfree` after Firmware & Wireless Setup.
- New `is_nvidia_blackwell()` detects GPUs in ranges `0x2900–0x29BF` and `0x2B80–0x31FF`. Added `_enable_cuda_repo()` helper for extrepo-based CUDA installation with APT pinning. DKMS verification blocks added to all `_install_nvidia_*` functions.
- Standardized repository enablement across 7 modules using `_enable_*_repo()` helpers:
- `internet.sh`: Firefox/Floorp/LibreWolf, Pale Moon, Tailscale, Mullvad VPN/Browser, ProtonVPN
- `jellyfin.sh`, `programming.sh` (VSCodium), `java.sh` (Temurin)
- New `extras/office/office.sh`: OnlyOffice + LibreOffice with language detection
- The main script was reduced from 233 to 137 lines. Created new `modules/sysinfo.sh` (97 lines) for `_show_sysinfo()`. Source chain: `utils.sh → sysinfo.sh → sudo_config.sh → repos → firmware.sh → bluetooth.sh → gpu.sh → kernel.sh → gaming.sh → extras.sh → zram.sh → java.sh`.
- Renamed menu to `"Firmware, Wireless & Bluetooth"`. Translated NTP dialog (English), basic programs install message, and NVIDIA 32-bit legacy messages.
- 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
- Refactored `is_backports_enabled()` to dynamically detect backports using `DEBIAN_CODENAME` instead of hardcoded strings, improving script portability.
- Added support for standalone classic backports files (`/etc/apt/sources.list.d/debian-backports.list`) and deb822 format (`*.sources`) to ensure consistent detection across different repository configurations.
- Resolved Mesa and Kernel backports detection bugs, ensuring correct dialogue prompts and preventing false error messages during installation.
- Implemented smart rounding for zram memory allocation to the nearest Gigabyte for optimized performance.
- Enhanced Whiptail manual input validation for zram to block empty, non-numeric, or zero values.
- Introduced a dedicated `software_centers.sh` module for the modular and clean installation of GNOME Software and Plasma Discover.
- Added smart desktop environment detection (GTK/QT) to automatically suggest and install the optimal software center.
- Implemented a two-phase installation flow for software centers (Base Store -> Optional Flatpak support) with static consistency warnings based on the detected desktop environment.
- update README.md
- Created dedicated `extras/java.sh` module for modular Temurin/Adoptium repository handling and isolated GPG key management.
- Implemented selective JRE/JDK installation paths: Gaming (Minecraft) vs Development environments with version control selectors.
- Enhanced user group membership logic (`_ensure_sudo_group`) to auto-configure administrative privileges on fresh installs.
- Introduced maintenance-friendly passwordless sudo for `apt`, `systemctl`, and shutdown commands via `/etc/sudoers.d/`.
- Added home directory ownership repair utility to fix root-owned files in user directories after improper `sudo` usage.
- Enabled visual password feedback (`pwfeedback`) toggle for enhanced terminal usability during authentication prompts.
- Refactored Debian 13/Trixie repository sourcing logic to ensure idempotency and prevent backports/duplicate sources conflicts.
- Updated Bullseye legacy modules (extras.sh, repos.sh) to exclude deprecated packages (`hx`, `vscodium`) and enforce Firefox ESR defaults.
- Cleaned repository configurations by removing obsolete `bullseye-updates` source entries to prevent dependency conflicts.
- Implemented NVTOP conditional detection logic ensuring display only on active Nvidia drivers or supported architectures (Trixie/Bookworm).
- Corrected `/modules/bullseye/extras.sh` menu mappings (Programming, Dev Tools) and verified package lists excluding incompatible tools (`hx`, `vscodium`).
- Integrated ClamAV security module with daemon state management and background scan execution flows in all Security menus.
- 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.
