Bug ID: 442736
Summary: wayland system hangs on lock session
Product: kscreenlocker
Version: unspecified
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: alexander.fier...@mpi-dortmund.mpg.de
CC: bhus...@gmail.com
Target Milestone: ---
Each time I lock my KDE session
- manually using the lock widget
- using the command line "loginctl lock-session"
- using xscreensaver which locks the screen after some minutes
the system hangs. Parts of my screen turn black but I can see the rest of the
screen. There is no login dialog or lock screen background. I also cannot
unlock my session by typing blind my credentials.
However, it does not kill the desktop session. I can switch to a terminal
CTRL+ALT+F1, login, and enter "loginctrl unlock-sessions". After switching back
to KDE Wayland session I can use it again.
I have an AMD graphic card using 3 screens by 3 display port output.
