Bug ID: 513384
Summary: Waking the computer right when computer goes to sleep
causes monitor to fail to turn back on
Classification: Plasma
Product: plasmashell
Version First 6.5.4
Reported In:
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: generic-crash
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: 1.0
SUMMARY
Attempting to wake the computer in the span of a couple seconds before or after
the computer goes to sleep will cause the computer to fail to wake up properly.
This does not appear to happen to all computers, but for computers that are
affected, it appears to be consistent and easy to replicate. Possible duplicate
of https://bugs.kde.org/show_bug.cgi?id=487660, but I'm not sure if they're the
same thing or if it's something different
STEPS TO REPRODUCE
1. Go to Power Management. Set dim automatically to 30 seconds (makes it easier
to time) and set when inactive to sleep after 1 minute
2. Get a timer. When the screen dims, start the timer for 30 seconds
3. Right when the timer runs out, move the mouse or press a key on the keyboard
to wake the computer
OBSERVED RESULT
LED's on the mouse, keyboard, etc. light up as though computer has been woken
up, but screen remains black. A hard shut down is the only way to restore
functionality
EXPECTED RESULT
The computer wakes up.
