System log from resuming system
SUMMARY
After updating KDE to 6.2.3 (and nvidia-open to 565.57.01-2), Plasma login
screen black with only mouse cursor visible after resuming from sleep.
STEPS TO REPRODUCE
1. Running plasma desktop session on X11
2. Sleep
3. Wake up computer
OBSERVED RESULT
Black screen with mouse cursor visible and movable. Moving cursor across the
screen, it can change to "text input" cursor when hovering over (invisible)
password box perhaps.
EXPECTED RESULT
Normal login screen after resuming from sleep.
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 6.2.3
KDE Frameworks Version: 6.7.0
Qt Version: 6.8.0
Kernel Version: 6.11.6-arch1-1 (64-bit)
Graphics Platform: X11
Processors: 8 × Intel® Core™ i7-9700K CPU @ 3.60GHz
Memory: 15.6 GiB of RAM
Graphics Processor: NVIDIA GeForce RTX 4070/PCIe/SSE2
ADDITIONAL INFORMATION
- Only happens with X11. When suspending from wayland session, login screen
works normally (but I can't use wayland day-to-day for other reasons).
- Only happens when suspending from Plasma session. When I log out to SDDM,
sleep there, resuming back to SDDM works ok.
- Attaching journal from resuming system - there are some suspicious looking
lines from plasmashell, like "QRhiGles2: Context is lost" or "Graphics device
lost, cleaning up scenegraph and releasing RHI", but when I grep my log for
these, they are present for months, and I was sleeping/resuming without issue
until last update.
