ProbeLabs65 findings · 95 requirementsA proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.

Describe the Bug
After installing Omarchy 4.0.4-1, the system boots to a blank black screen with no desktop, no bar, and no terminal. Super+Return does nothing. SDDM autologin succeeds but the graphical session never appears.
Steps to Reproduce
- Install Omarchy 4.0.4-1 on a system
- Boot and wait for SDDM autologin
- Observe: blank black screen, no desktop environment
Expected Behavior
After autologin, the Omarchy desktop (Hyprland + uwsm + Omarchy shell/bar) should appear.
System Information
- Omarchy: 4.0.4-1
- Kernel: 7.2.5-3-omarchy
- CPU: Intel Celeron 925 @ 2.30GHz (1 core, Penryn, 2008)
- GPU: Intel Mobile 4 Series Integrated Graphics (Sandy Bridge, i915 driver)
- RAM: 4GB
- Display: LVDS-1, 1366x768 @ 60Hz
- Machine: eMachines eME528 (HM55-MV motherboard)
- Firmware: Phoenix BIOS 1.3408 (02/14/2011)
Full debug: omarchy debug --no-sudo --print
Investigation
Issue A: Session file not in SDDM search path
The omarchy.desktop Wayland session file is installed to /usr/local/share/wayland-sessions/omarchy.desktop but SDDM only searches /usr/share/wayland-sessions/ for session files.
SDDM log shows it reads the file from the non-standard location:
Reading from "/usr/local/share/wayland-sessions/omarchy.desktop"
Session "/usr/local/share/wayland-sessions/omarchy.desktop" selected, command: "uwsm start -g -1 -e -D Hyprland hyprland.desktop" for VT 1This may not work on all SDDM configurations. The file should also be installed to /usr/share/wayland-sessions/ (the standard location per freedesktop.org spec).
Issue B: Session exits immediately after autologin
After the session is launched, SDDM shows the session starting then immediately removing the display:
Session started true
Auth: sddm-helper exited successfully
Removing display SDDM::Display(0x5f7fc82e6730) ...The omarchy.desktop session uses:
Exec=uwsm start -g -1 -e -D Hyprland hyprland.desktopThe -g -1 flag tells uwsm to use the greeter's display. After autologin, the greeter session is torn down and the display is removed — so the user session has nothing to attach to and exits.
Fix: Remove -g -1 from the Exec line (change to uwsm start -e -D Hyprland hyprland.desktop).
Issue C: No Hyprland process after boot
After boot, hyprctl returns HYPRLAND_INSTANCE_SIGNATURE not set! (is hyprland running?) — confirming Hyprland never started. No Hyprland process visible in ps aux.
Proposed Fixes
- Install
omarchy.desktopto/usr/share/wayland-sessions/in addition to/usr/local/share/wayland-sessions/ - Remove the
-g -1flag from the uwsm command inomarchy.desktop, or use a different display handoff approach for autologin - Investigate whether SDDM's
CompositorCommand=start-hyprland -- --config /usr/share/sddm/hyprland.luain the[Wayland]section conflicts with theomarchy.desktopsession launch
Additional Context
- SDDM autologin enabled:
User=abdo,Session=omarchy.desktop - Older GPU (Intel HD Graphics 2000, Sandy Bridge) — unknown if relevant
- Issue may be specific to autologin; manual login at SDDM may behave differently
