Bug ID: 517339
Summary: After unlocking screen, primary monitor appears to get
swapped, reapplying settings restores it
Classification: Plasma
Product: plasmashell
Version First 6.6.2
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
SUMMARY
I have my screens lock and then sleep. Upon wake and unlock, I regularly see
that my primary panel moved to my second monitor, and the background is black
on the primary screen, however windows remain where they were. Opening
settings, I still see the correct settings for primary screen. When I swap the
primary monitor setting, nothing changes, as that's my issue symptom in the
first place, and after swapping back the behaviour is restored and from this
point it works as intented. Tricky part is, this doesn't always seem to happen,
and I haven't been able to narrow it down.
STEPS TO REPRODUCE
1. Let the screen lock and sleep
2. Wake it and unlock
3. Observe main system panel moved to second screen
OBSERVED RESULT
Second screen acts as primary screen despite showing otherwise in settings
EXPECTED RESULT
Primary screen setting is respected
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux
KDE Plasma Version: 6.6.2
KDE Frameworks Version: 6.23.0
Qt Version: 6.10.2
ADDITIONAL INFORMATION
This started around Plama 6.6, but I also played around with HDR settings just
to see, I don't have a "real" HDR screen so I left it off, but I do however use
wide gamut mode which I toggle from kscreen-doctor, and I had to reapply after
that. I'm not sure those are related.
I also have a Valve Index HMD, which I have as disabled in screen settings, not
sure if that can mix things up. I'm running Wayland.
Also started around the same time and I'm not sure if related, but when I let
my screen sleep, wake and unlock it later, if games like World of Warcraft were
running, it reverts to a 640x480 resolution. I can set it back to the native
resolution and have it work unless it crashes.
