Displays managers & zram menu

- 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.

+## Option 11: Boot Rescue & Repair
+
+### 1. What does this component do?
+This component serves as a comprehensive rescue toolkit designed to diagnose and fix boot-related issues on Debian systems, specifically targeting GRUB configuration, UEFI Secure Boot integrity, and initrd image validity. It provides three primary operations: configuring the GRUB boot menu behavior (including timeout adjustments and visibility settings), repairing UEFI Secure Boot by reinstalling signed bootloader packages after kernel or driver changes, and regenerating initramfs images to resolve missing driver errors. All modifications are protected by automatic backup creation before system files are altered, with built-in rollback mechanisms that restore the original state if any operation fails during execution.
+
+### 2. Logical Execution Flow
+
+**Block 1 — GRUB Boot Menu Settings**
+- **Menu Options:** Users select from four presets or a custom option to control boot behavior:
+    1. Hide GRUB menu entirely (Fastest boot, requires holding ESC during power-on).
+    2. Show 3-second countdown (Faster boot).
+    3. Show menu for 5 seconds (Default behavior).
+    4. Custom timeout (User inputs specific seconds; -1 allows indefinite wait).
+- **Variable Application:** Each selection updates three core variables: `GRUB_TIMEOUT`, `GRUB_TIMEOUT_STYLE`, and `GRUB_RECORDFAIL_TIMEOUT`. The custom option also allows setting `GRUB_DISABLE_OS_PROBER` to prevent extra entries.
+- **Backup & Safety:** Before applying changes, the script creates a timestamped backup of `/etc/default/grub`. It writes an override configuration file at `/etc/default/grub.d/99_script_override.cfg` to ensure settings persist across updates.
+- **Execution & Rollback:** The system runs `update-grub` to apply changes. If this command fails, the script automatically restores the timestamped backup and removes the override file to prevent boot issues.
+
+**Block 2 — UEFI Secure Boot Repair**
+- **Pre-checks:** Before proceeding, the script verifies two conditions:
+    1. The system is running in UEFI mode (checks for existence of `/sys/firmware/efi`).
+    2. Secure Boot is currently enabled (uses `mokutil --sb-state` to confirm status).
+- **Skip Logic:** If either check fails, the process stops immediately with a message indicating no repair is needed or applicable.
+- **Repair Steps:** Upon user confirmation:
+    1. Reinstalls signed boot packages (`shim-signed`, `grub-efi-amd64-signed`, `linux-image-amd64`).
+    2. Reinstalls GRUB to the EFI partition using `grub-install` with the appropriate target and directory detection (preferring `/boot/efi` over `/boot`).
+    3. Regenerates the GRUB configuration via `update-grub`.
+
+**Block 3 — Initramfs Regeneration**
+- **Confirmation:** The script prompts for user confirmation before proceeding to avoid unintended rebuilds.
+- **Execution:** Upon approval, it runs `update-initramfs -u -k all` to regenerate initrd images for all installed kernels.
+- **Purpose:** This fixes boot issues caused by missing drivers or corrupted initrd images that prevent the system from loading properly.
+
+### 3. Intelligent Automation
+
+- **EFI Directory Detection:** The script intelligently detects the EFI partition, checking `/boot/efi` first and falling back to `/boot` if necessary.
+- **Secure Boot State Verification:** Instead of assuming Secure Boot is active, it uses `mokutil --sb-state` to verify the actual state before attempting repairs on non-UEFI or disabled systems.
+- **GRUB Backup Strategy:** A timestamped backup file (e.g., `/etc/default/grub.backup.YYYYMMDD_HHMMSS`) is created prior to any modification, ensuring a safe point for rollback.
+- **Rollback Mechanism:** If `update-grub` fails during the GRUB settings or Secure Boot repair process, the script automatically restores the backup and cleans up temporary override files.
+- **Override Persistence:** Configuration values are written to `/etc/default/grub.d/99_script_override.cfg`, ensuring that changes survive package updates which might otherwise reset `/etc/default/grub`.
+- **Input Validation:** Custom timeout inputs are validated using regex matching for integers (e.g., `^-?[0-9]+$`), allowing negative numbers like -1 while rejecting invalid text.
+- **Variable Handling Logic:** The `_set_grub_var()` function handles three distinct cases: updating an existing variable, uncommenting a commented variable, or appending a new variable if it does not exist in the configuration file.
+
+### 4. Paquetes y Recursos Gestionados
+
+**Boot Packages Reinstalled (Secure Boot Repair):**
+| Package | Purpose |
+|---|---|
+| shim-signed | UEFI Secure Boot shim (first-stage bootloader) |
+| grub-efi-amd64-signed | Signed GRUB for UEFI |
+| linux-image-amd64 | Kernel image (re-signed) |
+
+**GRUB Settings Modified:**
+| Variable | Option 1 | Option 2 | Option 3 | Custom |
+|---|---|---|---|---|
+| GRUB_TIMEOUT | 0 | 3 | 5 | User value |
+| GRUB_TIMEOUT_STYLE | hidden | menu | menu | menu |
+| GRUB_RECORDFAIL_TIMEOUT | 0 | 3 | 5 | User value |
+| GRUB_DISABLE_OS_PROBER | true | — | — | — |
+
+**System Files Modified:**
+| Package | Purpose |
+|---|---|
+| /etc/default/grub | Main GRUB configuration |
+| /etc/default/grub.d/99_script_override.cfg | Persistent override (survives grub updates) |
+| /etc/default/grub.backup.* | Timestamped backup (auto-created) |
+
+>**Note UEFI:** The Secure Boot repair ONLY works on UEFI systems. The script checks for `/sys/firmware/efi` and `mokutil --sb-state` before attempting anything. Legacy BIOS systems are automatically skipped.
+
+>**Note GRUB:** After hiding the GRUB menu (Option 1), you must hold ESC immediately after powering on to access the menu. There is no other way to reach it during boot.
+
+> **Technical data:** The override file at `/etc/default/grub.d/99_script_override.cfg` persists across kernel updates because GRUB reads drop-in configs from that directory. This is more reliable than editing `/etc/default/grub` directly for values that should survive updates.
+
+> **Technical data:** `GRUB_DISABLE_OS_PROBER=true` is set when hiding the menu to prevent OS prober from adding extra entries that would require the menu to appear. For multi-boot systems, use Option 3 or Custom instead.

+## Option 12: Desktop & Display
+
+### 1. What does this component do?
+This component manages display managers (the login screen you see before entering your desktop). It allows users to install and configure LightDM, GDM3, SDDM, or greetd. It handles autologin setup, user list visibility toggles, and a specific Wayland override for NVIDIA GPUs. Currently, Desktop Environment management is marked as "Coming Soon".
+
+### 2. Logical Flow of Execution
+The execution logic is divided into five functional blocks:
+
+**Block 1 — Display Manager Selection**
+- The main menu offers two primary options within Option 12: "Desktop Environment" (currently unavailable) and "Display Manager".
+- Selecting "Display Manager" opens a submenu listing available display managers based on the Debian version.
+- **Available Managers:**
+  - LightDM (available on all Debian versions).
+  - GDM3 (available on all Debian versions).
+  - SDDM (available on all Debian versions).
+  - greetd (available only on Debian 12 and 13).
+- Each selected manager opens its own dedicated configuration submenu.
+
+**Block 2 — LightDM Configuration**
+- A checklist menu presents three options:
+  1. Install LightDM + GTK Greeter (auto-selects the display manager via debconf-set-selections).
+  2. Enable user list at login screen (writes `greeter-hide-users=false` to a configuration file in `.conf.d`).
+  3. Enable autologin for current user (uncomments `autologin-user` and sets timeout to 0 in the main config).
+- **Idempotency:** The script checks if `lightdm` and `lightdm-gtk-greeter-settings` are already installed before attempting installation, skipping redundant steps.
+
+**Block 3 — GDM3 Configuration**
+- A checklist menu presents up to four options:
+  1. Install/Reinstall gdm3 (auto-selects via debconf).
+  2. Toggle user list visibility (toggles `disable-user-list` in greeter.dconf-defaults).
+  3. Configure autologin (prompts for a username via whiptail inputbox to set in daemon.conf).
+  4. Force Enable Wayland on NVIDIA (Bookworm/Trixie + NVIDIA only).
+     - **Mechanism:** Creates or removes a symlink: `/etc/udev/rules.d/61-gdm.rules` → `/dev/null`.
+     - **Purpose:** This disables the udev rule that blocks GDM from using Wayland on NVIDIA GPUs.
+     - **Risk Warning:** Displays a warning that this may break graphics or cause instability.
+     - **Toggle Behavior:** If the symlink exists, removing it reverts to default behavior; if not present, creating it enables the override.
+
+**Block 4 — SDDM Configuration**
+- A submenu offers two options:
+  1. Install SDDM (auto-selects via debconf).
+  2. Enable Autologin:
+     - **Session Detection:** Auto-detects the installed session by checking `.desktop` files in priority order: `plasmawayland` → `lxqt-wayland` → `plasma` → `lxqt`.
+     - **Configuration:** Writes autologin settings to `/etc/sddm.conf.d/autologin.conf`.
+     - **Fallback:** If no session is found, it enables autologin but warns that SDDM will use the default session.
+
+**Block 5 — greetd Configuration**
+- greetd is a minimal, modern display manager designed for Wayland environments.
+- Submenu options vary by Debian version:
+  - **All Versions:** Install base `greetd`, Install `greetd` + `tuigreet` (recommended TUI greeter).
+  - **Debian 13 only:** Additional options to install `gtk-greet`, `nwg-hello`, or `wlgreet`.
+- **Backports Handling:** On Bookworm, `tuigreet` is installed from backports if not enabled.
+- **Important Warning:** greetd is installed but NOT configured by the script. The user must manually create `/etc/greetd/config.toml` to be able to log in. The script displays a warning with references to man pages for configuration details.
+
+### 3. Smart Automations
+The component utilizes several intelligent automation features:
+- **debconf-set-selections:** Pre-selects the display manager as default before `apt install`, preventing the interactive "Configuring shared/default-x-display-manager" dialog that would otherwise pause the script execution.
+- **Session Auto-Detection (SDDM):** Checks `.desktop` files in priority order (Wayland first, then X11) to set the correct session type for autologin configuration.
+- **Wayland Toggle:** Creates or removes a udev rule symlink to `/dev/null`. This is a known workaround that disables the GDM rule blocking NVIDIA Wayland support.
+- **greetd Backports:** On Bookworm, `tuigreet` is installed from backports (newer version) if not already enabled in the system.
+- **Manual Config Warning:** The script explicitly informs users that greetd requires manual configuration and points to man pages for further details.
+- **User Detection:** Uses `SUDO_USER` (the real user who ran sudo) instead of `$USER` (which is root during script execution). This ensures the correct user is set for automatic login across all display managers.
+
+### 4. Packages and Resources Managed
+
+**Display Manager Packages:**
+| DM | Packages | Debian Versions |
+|---|---|---|
+| LightDM | lightdm, lightdm-gtk-greeter, lightdm-gtk-greeter-settings | All |
+| GDM3 | gdm3 | All |
+| SDDM | sddm | All |
+| greetd (base) | greetd | 12, 13 |
+| greetd + tuigreet | greetd, tuigreet | 12 (backports), 13 |
+| greetd + gtk-greet | greetd, gtk-greet | 13 only |
+| greetd + nwg-hello | greetd, nwg-hello | 13 only |
+| greetd + wlgreet | greetd, wlgreet | 13 only |
+
+**Configuration Files Modified:**
+| DM | File Path | Configuration Purpose |
+|---|---|---|
+| LightDM | /etc/lightdm/lightdm.conf.d/50-debianito-userlist.conf | User list visibility toggle |
+| LightDM | /etc/lightdm/lightdm.conf | Autologin user + timeout settings |
+| GDM3 | /etc/gdm3/greeter.dconf-defaults | User list toggle (disable-user-list) |
+| GDM3 | /etc/gdm3/daemon.conf | Autologin user and enable flag |
+| GDM3 | /etc/udev/rules.d/61-gdm.rules | Wayland override (symlink to /dev/null) |
+| SDDM | /etc/sddm.conf.d/autologin.conf | Autologin user + session type |
+
+**Session Detection Priority (SDDM Autologin):**
+| Priority | Session File | Session Type |
+|---|---|---|
+| 1 | /usr/share/wayland-sessions/plasmawayland.desktop | KDE Wayland |
+| 2 | /usr/share/wayland-sessions/lxqt-wayland.desktop | LXQt Wayland |
+| 3 | /usr/share/xsessions/plasma.desktop | KDE X11 |
+| 4 | /usr/share/xsessions/lxqt.desktop | LXQt X11 |
+
+> ⚠️ **Warning: Wayland on NVIDIA:** The "Force Enable Wayland on NVIDIA" option creates a symlink that disables the GDM udev rule. This is a known workaround but MAY cause graphics instability or breakage. To revert, remove `/etc/udev/rules.d/61-gdm.rules`.
+
+> ⚠️ **Warning: greetd:** Unlike other display managers, greetd is installed but NOT configured by this script. You MUST manually create `/etc/greetd/config.toml` before you can log in. See `man greetd` and `man 5 greetd-sessions` for configuration details.
+
+> ⚠️ **Warning: Autologin:** All autologin configurations use `SUDO_USER` (the user who ran sudo) instead of `$USER` (which is root during script execution). This ensures the correct user is set for automatic login.
+
+> 💡 **Technical Note:** `debconf-set-selections` pre-selects the display manager before apt install, preventing the interactive "Configuring shared/default-x-display-manager" dialog that would otherwise pause the script.

+## Option 9: Swap
+
+### 1. What does this component do?
+This module is responsible for the secure management of disk-based swap space within the `debianito` environment. Unlike standard Linux tools that might overwrite existing configurations or conflict with memory compression features (like ZRAM), this script operates as a **priority-aware, persistent swap manager**.
+
+Its primary functions include:
+*   **Dynamic Allocation:** Creating and resizing swapfiles based on detected RAM capacity without requiring physical partition changes.
+*   **Priority Integration:** Explicitly setting the swap priority (`pri=10`) to ensure it sits below ZRAM (which uses `priority=100`). This prevents the system from using disk I/O for memory swapping until compressed RAM is exhausted, optimizing performance.
+*   **Persistence Management:** Safely editing `/etc/fstab` with a unique tag (`# debianito-managed-swap`) to ensure swap survives reboots without corrupting manual entries.
+*   **Safety Locking:** Prevents concurrent operations using file locking mechanisms to avoid race conditions during active system usage.
+
+### 2. How does it work?
+The script leverages several advanced Linux subsystems and safety protocols:
+
+1.  **File System Detection:** It identifies the filesystem type of the target partition (e.g., `ext4`, `btrfs`). For Btrfs, it applies specific flags (`chattr +C` for copy-on-write optimization) to prevent performance degradation during swap operations.
+2.  **Allocation Strategy:** It prefers `fallocate` for instant space reservation on supported filesystems, falling back to `dd if=/dev/zero` for compatibility or zeroing requirements (like Btrfs).
+3.  **Fstab Validation:** Before writing changes to `/etc/fstab`, it creates a temporary file and validates the syntax using `findmnt --verify`. If validation fails, the script aborts and restores the original state.
+4.  **Concurrency Control:** It utilizes `flock` on `/run/lock/debianito-swap.lock`. This ensures that if another process is modifying swap settings (e.g., a system update), this script will wait or exit gracefully to prevent filesystem corruption.
+5.  **Swappiness Tuning:** It configures `vm.swappiness` via both runtime (`sysctl -w`) and persistent (`/etc/sysctl.d/99-swappiness-debianito.conf`) mechanisms, defaulting to values that favor RAM usage over disk swapping (e.g., 10-20).
+
+### 3. The Logical Decision Tree (Step by Step)
+The execution flow follows a strict logical tree designed for safety and idempotency:
+
+1.  **Initialization & Locking:**
+    *   The `manage_swap()` function attempts to acquire an exclusive lock (`flock -n`). If the lock is held by another process, it immediately exits with a "Busy" message to prevent conflicts.
+
+2.  **Menu Selection Loop:**
+    *   Enters a continuous loop presenting options (Status, Create, Remove, Swappiness).
+    *   Breaks only when the user selects "Back to main menu".
+
+3.  **Action Execution Paths:**
+    *   **Path A: Status Check (`_swap_current_status`)**
+        *   Reads active swap entries via `swapon --show`.
+        *   Reads current swappiness from `/proc/sys/vm/swappiness`.
+        *   Parses `/etc/fstab` for managed tags.
+    *   **Path B: Create/Resize (`_swap_create_file`)**
+        *   **Recommendation:** Calculates optimal size based on RAM (e.g., 2GB for >16GB RAM, 4GB for 8-16GB).
+        *   **Btrfs Check:** If the filesystem is Btrfs, it warns about `nodatacow` requirements and hibernation limitations.
+        *   **Existence Check:** If `/swapfile` exists, it prompts to confirm recreation (deleting old data first via `swapoff`).
+        *   **Allocation:** Uses `fallocate` or `dd` to zero the file. Sets permissions (`chmod 600`) and initializes swap (`mkswap`).
+        *   **Persistence:** Attempts to write the new entry to `/etc/fstab`. If validation fails, it cleans up (removes file) before exiting.
+    *   **Path C: Remove (`_swap_remove_file`)**
+        *   Checks for the unique `SWAP_FSTAB_TAG` in fstab.
+        *   Confirms user intent to delete.
+        *   Executes `swapoff`, removes the fstab line, and deletes the physical file.
+    *   **Path D: Swappiness (`_swap_set_swappiness`)**
+        *   Validates input (0-100 integer).
+        *   Writes a temporary sysctl config file.
+        *   Applies changes immediately via `sysctl -w`.
+
+### 4. What does each menu item do and what does it mean?
+Each option in the swap management submenu serves a specific technical purpose:
+
+*   **Option 1: Show current swap & swappiness**
+    *   **Technical Action:** Aggregates data from `/proc/swaps`, `/proc/sys/vm/swappiness`, and `/etc/fstab`.
+    *   **Significance:** Provides an audit trail of the current memory management state. It verifies if ZRAM is active (implied by priority check) and how much disk swap is currently in use.
+
+*   **Option 2: Create / resize swapfile**
+    *   **Technical Action:** Allocates a new block device file (`/swapfile`) or expands an existing one. Sets the `pri=10` flag to ensure it acts as a secondary memory layer after ZRAM fills up.
+    *   **Significance:** Essential for systems with low RAM that need overflow protection without installing physical partitions. The "Resize" capability allows adapting to new hardware configurations dynamically.
+
+*   **Option 3: Remove swapfile**
+    *   **Technical Action:** Disables the swapfile (`swapoff`), removes it from `/etc/fstab`, and deletes the file from disk.
+    *   **Significance:** Useful for troubleshooting, freeing up disk space (e.g., on SSDs where write cycles are a concern), or migrating to ZRAM-only configurations if RAM is sufficient.
+
+*   **Option 4: Change swappiness**
+    *   **Technical Action:** Modifies the kernel parameter `vm.swappiness`.
+    *   **Significance:** Controls the "aggressiveness" of swapping. A lower value (e.g., 10) tells the kernel to keep data in RAM longer, only using swap as a last resort. This is critical for desktop performance and battery life on laptops.
+
+*   **Option 5: Back to main menu**
+    *   **Technical Action:** Releases the file lock (`exec 9>&-`) and terminates the submenu loop.
+    *   **Significance:** Returns control to the user, ensuring no swap operations are running in the background before they navigate to other system configurations.
