Summary: Screen resolutions bumps down 1024x768 after wake from
sleep of both screen power save and also from system
power save.
Classification: Plasma
Product: kwin
Version: 5.92.0
Platform: Other

Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
When i boot my system to plasma wayland session my screen resolution is FHD
(1920x1080@60hz) .
But when either screen or system goes into powersave mode, and i wake computer
og turn screen power save off by presseing a key on keyboard, the computer
comes back up but then screen resolution is lost and now is bumped down to
1024x768.
I can restore the resolution from system settings display settings or by
sending "kscreen-doctor output.HDMI-A-1.mode.1920x1080@60" from command line.
STEPS TO REPRODUCE
1. Wait for a powersave event to occur happens on both screen power save or
after wake to resume of system power save
2. Press any key to resume from power save
3. The resolution is bumped down to 1024x768
4. These 3 action restore my 1920x1080 resolution:
1) A reboot fixes resolution, 2) kscreen-doctor cmd above, or 3) using System
settings display option to restore also works fine.
OBSERVED RESULT
Screen resolution is lost on power save events
EXPECTED RESULT
Screen resolution to stay at 1980x1080 as configured for the System using
System Settings. And which have been set and in effect as a reboot will set
this resolution at reboot. Only after a power save event is the resolution
lost...
