Bug ID: 442969
Summary: KWin Wayland doesn't wake up the screen after it turns
off anymore
Product: kwin
Version: git master
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: platform-drm
Assignee: kwin-bugs-n...@kde.org
Reporter: bharadwaj.raju...@protonmail.com
Target Milestone: ---
SUMMARY
After a recent git master update (+git20210923.0148-0), KWin Wayland doesn't
wake a screen which turned off due to energy saving. Moving the mouse, typing
on the keyboard, none work. The system isn't frozen, just not waking up.
Trying to switch VT with Ctrl+Alt+FN doesn't work either. Unplugging and
replugging the VGA cable works, but has unrelated issues (plasmashell seems to
crash, windows go offscreen, but that's for another report).
wayland-session.log says:
kwin_wayland_drm: Setting active to false failed Resource temporarily
unavailable
kwin_wayland_drm: Page flip failed: Invalid argument
QSharedPointer(0x557ca9d1e850)
kwin_wayland_drm: Present failed! Invalid argument
The last two lines are repeated over and over again.
STEPS TO REPRODUCE
1. Let the screen turn off due to power saving
2. Try to wake it up by moving the mouse etc.
OBSERVED RESULT
Screen does not wake up.
EXPECTED RESULT
Screen wakes up.
