Hi,
I’m experiencing an issue where after the screen turns off (idle 30 minutes), when I move the mouse and wake it up, the resolution sometimes changes from 1920x1080 to 640x400.
This does not happen consistently:
- Sometimes it happens after 30 minutes
- Sometimes after several hours nothing changes
- Happens regardless of what is on screen (desktop, Firefox, etc.)

Important note:
I currently have GNOME (Manjaro) installed on the same PC, and I do not experience this issue there.
The issue was first noticed after a system update around December 2025.
Additional info:
- Wayland session (kwin_wayland)
- No custom Xorg configuration
- Single monitor setup
- Issue happens after screen power-off, not full suspend
If you have any additional questions, feel free to ask.
