Bug ID: 449084
Summary: Issue with idling on lock-screen when auto-sleep mode
is disabled on wayland KDE. Freeze on return
Product: plasmashell
Version: 5.23.5
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org
Reporter: imilar...@gmail.com
Target Milestone: 1.0
SUMMARY
There is a minor issue with KDE where when auto-sleep mode is disabled and the
computer is left idling. The screen auto locks as intended but if left alone
will freeze upon unlocking the session and a couple seconds of mouse movement.
When the session freezes all input is ignored including the standard
Ctrl+Alt+F5 to try to get to a login shell. Sometimes it breaks out of the
freeze on its own but other times the only cure is to hard restart the
computer. I have found turning auto-sleep mode back on avoids this issue
thankfully.
STEPS TO REPRODUCE
1. Start a wayland KDE session from sddm
2. Set the power save mode to only lock the screen upon idle instead of going
to sleep mode
3. Wait until the screen locks itself from idling or a little longer
4. Unlock the screen and attempt to use the computer
OBSERVED RESULT
Screen is frozen and all inputs are ignored. Either it unfreezes on its own or
a hard reboot is needed. If it decides to unfreeze the results of the
previously ignored inputs are then shown. Audio seems to work when it is frozen
as it still plays youtube videos in the background when it is frozen like this.
EXPECTED RESULT
Successful unlocking of the KDE session followed by standard use of the desktop
environment.
