Advanced keyboard driven Desktop Environment

Custom Linux desktop environment built on EXWM and Elisp programming language, integrated with Xorg.

Core Window Management

• Built on **EXWM** (Emacs X Window Manager) with Xorg display server.
• Supports **line-mode / char-mode** switching for flexible key handling.
• Custom `anup/other-window` implementation for **multi-monitor aware window cycling**.
• Mouse-focus handling via **exwm-mff** (mouse follows focus).
• Window titles auto-renamed based on **application class + page title/URL**.
• Configured **multi-monitor setups** (single, dual, triple) with `exwm-randr` hooks and custom refresh logic.
• Defined custom **workspace-to-monitor mappings** (iMac + vertical + horizontal monitors).
• Functions to move buffers across monitors (`C-c RET`).
• Implemented `exwm-randr-refresh2` to fix EXWM triple monitor refresh bugs.

Input & Keybindings

• Unified **global keybinding overrides** across all frames/monitors.
• Mapped Emacs-style navigation (`C-n`, `C-p`, `C-f`, `C-b`, etc.) to X11 windows.
• Copy/paste and undo mapped (`M-w`, `C-w`, `C-y`, `C-/`) consistently across Emacs and X apps.
• Custom bindings for Google Chrome & Qutebrowser (reload, copy, navigation).
• Added simulation keys for word/paragraph navigation, delete, select-all, etc.
• Shortcuts for **launching external apps** (`C-c p`).
• Disabled unused EXWM defaults (fullscreen, floating, hiding).
• Made VS Code and Edwin always open in **char-mode**.

Application Integration

• **Web browser integration**: Buffer names auto-sync with URL/title → enables **completion-based tab switching**.
• Configured **qutebrowser session auto-wipe** on logout to avoid session restore.
• Integrated **helm-exwm** for better Emacs vs EXWM buffer listing.
• Added support for **exwm-edit** (edit textareas of X apps inside Emacs).
• Leechblock-like filtering for Chrome app launch list.

UI & Usability

• Responsive **multi-monitor DPI compromise** hacks (font resizing on iMac screen).
• Adjusted **fringe size**, disabled scrollbars/menu-bar for a cleaner look.
• Implemented **mouse auto-hide** with unclutter.
• Custom fallback cursor (`xsetroot -cursor left_ptr`).
• Font scaling hooks triggered after EXWM init.
• Blackout screen on logout (disabled due to bugs).
• Auto-bury windows from drawing tablet settings panel.

Startup & Autostart

• System initialization via `~/.xinitrc` integrated into EXWM hooks.
• Auto-start services:
  • **Dropbox client**
  • **NetworkManager applet**
  • **Drawing tablet driver reload** (usbreset integration)
  • **Pulseaudio / pamixer** volume control bindings
  • **unclutter** (auto-hide mouse)
  • **disable screen blanking / DPMS**
• Configured **keyboard repeat rate** (200ms delay, 60/s repeat).
• Environment variables for **XDG compliance**, GTK/QT integration, Java non-reparenting WM flag.
• Planned autostart for compositor (xcompmgr), notifications (dunst), and polkit manager.

System Management

• Functions to **shutdown, reboot, suspend, or kill X server** directly from Emacs.
• Custom graceful shutdown hook bound to `kill-emacs`.
• Functions to programmatically send keys (via xdotool) to background X apps (e.g., Rails app reload).

Buffer & Completion System

• Fixed Helm/Ivy buffer switching to include EXWM buffers from all frames.
• Customized helm/ivy **boring buffer filters** to hide temp, compile logs, mpv windows, etc.
• Improved buffer switching completion (`C-x b`) ordering and filtering logic.
• Dynamic completion integration across Emacs + X windows.

Miscellaneous

• Auto-start and reset **drawing tablet driver** with usbreset + passwordless sudo.
• Added **custom kill-ring browser** (`M-y`) integration.
• Configurable **single / dual / triple monitor setups** via elisp functions.
• Optional keybinding hacks (`C-s`, `C-k`, `C-o`, `M-<`, `M->`) mapped consistently to X apps.
• Infrastructure for future keyboard remaps (CapsLock → Ctrl, trackpad disable).
