Bug ID: 456803
Summary: Plasma crashes after screen inactivity
Product: plasmashell
Version: 5.25.3
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org
Reporter: almur....@gmail.com
Target Milestone: 1.0
SUMMARY
Turning screens on after the screens turned themselves off for inactivity makes
plasmashell crash.
Once they are off
STEPS TO REPRODUCE
1. Using Wayland with two Displayport screens, let KDE be without interacting
until the two screens turn themselves off for inactivity.
2. Once they are off, come back to the computer and move the mouse to wake the
screens up
3. Observe at least plasma crashing, if not failing to wake screens up at all
(in which case, a hard reset is required)
4. If the screens were to come back up correctly, logging in with the password
shows the unlock button and it does not continue the login procedure, hanging
there, since plasma crashed behind the scenes.
OBSERVED RESULT
Plasma crashes and sometimes fails to wake up screens.
journalctl shows multiple instances of:
plasmashell[1473]: qt.qpa.wayland: Wayland does not support
QWindow::requestActivate()
and multiple instances of:
plasmashell[1473]: requesting unexisting screen 3
EXPECTED RESULT
The screens should wake up normally and plasma should not crash.
