Bug ID: 516397
Summary: Display stops working before/after unlocking screen
Classification: I don't know
Product: kde
Version First unspecified
Reported In:
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Screen turns "blank" instead of showing unlock screen/desktop before/after
unlocking screen.
STEPS TO REPRODUCE
1. use fedora 43 few days, locking/unlocking screen several times during
2. with screen locked and black and without background light on, press key yet
another time to see unlock screen menu
OBSERVED RESULT
Backlight switches on but screen stays blank/black otherwise. Also happened
once that unlock menu appeared but after unlocking everything went black except
for backlight. Otherwise everything seems to work, programs running in konsole
keep working, etc. After waiting backlight turns off and pressing something
switches it back on but otherwise nothing visible happens. Am also able to log
in even without seeing unlock menu, switching to another desktop with root
terminal using keyboard, and running shutdown -r now without seeing anything.
EXPECTED RESULT
Normal operation
