Bug ID: 498709
Summary: kscreenlocker_greet will not allow me to log in after
locking the screen for a while
Classification: Plasma
Product: plasmashell
Version: 5.27.11
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: Screen locking
Assignee: plasma-b...@kde.org
Reporter: m...@earlruby.org
Target Milestone: 1.0
SUMMARY
kscreenlocker_greet will not allow me to log in after locking the screen for a
while.
STEPS TO REPRODUCE
On a fresh Kubuntu 24.04 system with two monitors:
1. In "System Settings > Power Management > Energy Saving > On AC Power" check
that Suspend Session is set to "Lock Screen" (not Sleep).
2. Go away for a while.
3. When returning, click a key or move the mouse to activate the screen.
4. Can't login.
OBSERVED RESULT
One of two things happens:
1. The password text box does not appear at all (just the background image).
2. The password box appears but will not accept keyboard input. (Mouse
pointer is active)
To recover I have to ctrl-alt-F3 to get a terminal, login, then kill -9 the
kscreenlocker_greet process. After that the kglobalaccel process will start
consuming 100% of CPU so I have to kill that process too.
Once I do that I can ctrl-alt-F2 to get back to the GUI lock screen, wait a few
seconds, the login password box appears and I can log in.
If I leave the system alone long enough for the screen to lock the same thing
happens again.
EXPECTED RESULT
I should be able to log back into the system.
