# ADR 0007: Workstation Package Cleanup — Remove X11/KDE Legacy Stack
|
|
|
|
**Date**: 2026-05-22
|
|
**Status**: Accepted (Tier 1+2+3+4 executed 2026-05-22)
|
|
**Decision Maker**: Michael Wegener
|
|
|
|
## Context
|
|
|
|
The workstation runs Hyprland (Wayland) with greetd+tuigreet. Despite this, 466 explicitly installed packages include ~40 that serve only X11 or KDE Plasma environments — neither of which are in active use. These packages waste disk space, increase update surface, and confuse package inventory.
|
|
|
|
### Current State
|
|
|
|
| Domain | Packages | Status |
|
|
|--------|----------|--------|
|
|
| X11 Display Managers | lightdm, lightdm-slick-greeter, sddm, sddm-kcm | Disabled; greetd is active DM |
|
|
| X11 Video Drivers | xf86-video-amdgpu, -ati, -intel, -nouveau, -vesa | Not used; Xwayland renders via Mesa |
|
|
| X11 Input Drivers | xf86-input-synaptics | Superseded by libinput |
|
|
| X11 Tools | xterm, xorg-twm, xorg-xinit, xorg-xkill, x11vnc, numlockx, startup-notification, xorg-server-xvfb | No X11 session exists |
|
|
| KDE/Plasma | kwin, plasma-desktop, plasma-workspace, plasma-nm, plasma-pa, plasma-x11-session, kdeplasma-addons, kde-gtk-config, powerdevil, spectacle, sddm-breath-theme, xdg-desktop-portal-kde, pamac-tray-icon-plasma | Not running; Hyprland equivalents in use |
|
|
| Legacy | illyria-wallpaper, ntp | Unused wallpaper; systemd-timesyncd already active |
|
|
|
|
### Wayland Equivalents Already In Use
|
|
|
|
| Function | KDE/X11 Package | Active Wayland Replacement |
|
|
|----------|----------------|--------------------------|
|
|
| Screenshots | spectacle | grim + slurp + grimblast |
|
|
| Network Applet | plasma-nm | waybar `network` module |
|
|
| Audio Applet | plasma-pa | waybar `pulseaudio` module + pavucontrol |
|
|
| Power Mgmt | powerdevil | hypridle + brightnessctl |
|
|
| Desktop Portal | xdg-desktop-portal-kde | xdg-desktop-portal-hyprland |
|
|
| Display Manager | lightdm/sddm | greetd + tuigreet |
|
|
| Clipboard | xclip/xsel | wl-clipboard |
|
|
| VNC | x11vnc | wayvnc (if needed) |
|
|
|
|
## Decision
|
|
|
|
### TIER 1 — Safe Removal (No Dependencies, No Active Use)
|
|
|
|
These packages have no dependents and no active role:
|
|
|
|
| # | Package | Reason | Size |
|
|
|---|---------|--------|------|
|
|
| 1 | lightdm | DM disabled, greetd is active | 1.1 MiB |
|
|
| 2 | lightdm-slick-greeter | Only required by lightdm | 1.9 MiB |
|
|
| 3 | sddm | DM disabled | 5.3 MiB |
|
|
| 4 | sddm-kcm | Only required by sddm | 0.6 MiB |
|
|
| 5 | sddm-breath-theme | Manjaro KDE branding for sddm | 0.2 MiB |
|
|
| 6 | xterm | X11 terminal; kitty is active | 1.1 MiB |
|
|
| 7 | xorg-twm | X11 window manager | 0.2 MiB |
|
|
| 8 | xorg-xinit | Start X manually (no X11 session) | 0.04 MiB |
|
|
| 9 | xorg-xkill | X11 kill utility | 0.02 MiB |
|
|
| 10 | x11vnc | Only works with X11; wayvnc for Wayland | 1.8 MiB |
|
|
| 11 | numlockx | X11-specific numlock | 0.02 MiB |
|
|
| 12 | startup-notification | X11 startup protocol | 0.06 MiB |
|
|
| 13 | xorg-server-xvfb | Virtual framebuffer; no CI use case | 2.0 MiB |
|
|
| 14 | xf86-video-amdgpu | AMD X11 driver (system has NVIDIA) | 0.2 MiB |
|
|
| 15 | xf86-video-ati | ATI X11 driver (no ATI GPU) | 0.5 MiB |
|
|
| 16 | xf86-video-intel | Intel X11 driver (no Intel GPU) | 2.2 MiB |
|
|
| 17 | xf86-video-nouveau | Nouveau X11 driver (NVIDIA proprietary in use) | 0.2 MiB |
|
|
| 18 | xf86-video-vesa | VESA fallback driver | 0.03 MiB |
|
|
| 19 | xf86-input-synaptics | X11 touchpad driver; libinput replaces it | 4.0 MiB |
|
|
| 20 | illyria-wallpaper | Manjaro wallpaper; not used | 1.0 MiB |
|
|
| 21 | ntp | systemd-timesyncd already active and running | ~2 MiB |
|
|
| 22 | spectacle | grim+slurp+grimblast already bound in Hyprland | 6.1 MiB |
|
|
| 23 | pamac-tray-icon-plasma | pamac not running; paru is AUR helper | 0.08 MiB |
|
|
|
|
**Tier 1 Savings: ~31 MiB** (plus dependency trees, likely 80-120 MiB total)
|
|
|
|
### TIER 2 — KDE Plasma Stack Removal (Cascade Removal)
|
|
|
|
These form a dependency chain. Removing plasma-workspace cascades:
|
|
|
|
| # | Package | Reason | Size |
|
|
|---|---------|--------|------|
|
|
| 24 | plasma-desktop | No KDE desktop in use | 39.3 MiB |
|
|
| 25 | plasma-workspace | Not running; waybar replaces | 55.1 MiB |
|
|
| 26 | kwin | Not running; Hyprland is compositor | 30.9 MiB |
|
|
| 27 | kdeplasma-addons | Requires kwin+plasma-workspace | 12.0 MiB |
|
|
| 28 | plasma-nm | waybar network module in use | 12.8 MiB |
|
|
| 29 | plasma-pa | waybar pulseaudio module in use | 1.9 MiB |
|
|
| 30 | plasma-x11-session | X11 session; Hyprland is active | 3.4 MiB |
|
|
| 31 | kde-gtk-config | KDE GTK integration; not needed | 0.3 MiB |
|
|
| 32 | powerdevil | hypridle replaces | 5.9 MiB |
|
|
| 33 | xdg-desktop-portal-kde | xdg-desktop-portal-hyprland in use | 2.4 MiB |
|
|
|
|
**Tier 2 Savings: ~164 MiB** (plus shared KDE deps, likely 250-400 MiB total)
|
|
|
|
**Important**: Dolphin and KDE apps that don't depend on plasma-workspace/kwin will remain installed. Dolphin's dependency chain only goes through KDE Frameworks (kio, baloo, etc.), not plasma-workspace.
|
|
|
|
### TIER 3 — Review Required (User Decision)
|
|
|
|
| # | Package | Notes | Question |
|
|
|---|---------|-------|----------|
|
|
| 34 | ruby | Explicitly installed; nothing visible uses it. ~50 ruby-* subpackages exist as deps. | Is anything using Ruby? |
|
|
| 35 | love | LÖVE 2D game engine. 4.1 MiB. No .love files found. | Still needed? |
|
|
| 36 | xorg-server | Required by lightdm+sddm (both being removed). xorg-xwayland is separate and will remain. | Remove after Tiers 1+2? |
|
|
| 37 | xf86-input-libinput | Required by xorg-server. If xorg-server goes, this can go too. | Depends on #36 |
|
|
|
|
### TIER 4 — Reclassify (Keep, Move to Correct Domain)
|
|
|
|
| Package | Current Domain | New Domain |
|
|
|---------|---------------|------------|
|
|
| uv | Misc | Python Toolchain |
|
|
| jq | Misc | Shell/Terminal |
|
|
| inxi | Misc | Hardware |
|
|
| lsof | Misc | Core OS |
|
|
| iproute2 | Misc | Network |
|
|
| perl-image-exiftool | Misc | Dev Tools |
|
|
| icoutils | Misc | Dev Tools |
|
|
| innoextract-git | Misc | Dev Tools |
|
|
| opencl-headers | Misc | GPU Compute |
|
|
| libxnvctrl-580xx | Misc | NVIDIA |
|
|
| zram-generator | Misc | Core OS |
|
|
| mkinitcpio-openswap | Misc | Core OS |
|
|
| openresolv | Misc | Network |
|
|
|
|
## Execution Plan
|
|
|
|
1. **Tier 1**: Remove 23 packages via Ansible + `pacman -Rns` (safe, no dependents)
|
|
2. **Tier 2**: Remove 10 KDE Plasma packages (cascade; verify dolphin survives)
|
|
3. **Tier 3**: Get user decisions, then act
|
|
4. **Tier 4**: Reclassify in Ansible vars (no removal, documentation only)
|
|
5. **Verify**: Run `ansible-playbook --check` after each tier
|
|
6. **Document**: Update `docs/tech/stack.md` and CHANGELOG.md
|
|
|
|
### Safety
|
|
|
|
- xorg-xwayland stays (required by Hyprland for X11 app compatibility)
|
|
- xf86-input-libinput stays if xorg-server stays (Tier 3 decision)
|
|
- Dolphin and all KDE Frameworks libs stay (no dependency on plasma-workspace)
|
|
- Backup: `pacman -Qe` snapshot before execution
|
|
|
|
## Expected Outcome
|
|
|
|
| Metric | Before | After |
|
|
|--------|--------|-------|
|
|
| Explicit packages | 466 | ~425-430 |
|
|
| Disk freed | — | 300-500 MiB |
|
|
| X11 surface area | 24 packages | 1-2 (xorg-xwayland + maybe xorg-server) |
|
|
| KDE Plasma | 13 packages | 0 |
|
|
| Update complexity | High | Reduced |
|
