Not sure whether this is related:
Kwin crashes every time I wake from suspend if the monitor is powered down when
the system wakes. This is a replicable bug on my system.
The crash only occurs when I manually power down the monitor after suspend
(which is necessary in my case), then attempt to wake from sleep *before*
powering the monitor back up. If I power up the monitor before wake, the bug
does not occur.
Crash text simply says:
`Application: KWin (kwin_x11), signal: Segmentation fault`
Furthermore, when clicking the button on the bug report app to install missing
symbols for the backtrace, the process fails with an error stating the packages
cannot be installed. No additional information is presented, nor does it say
what the missing packages are.
Clicking the link below that bug report dialog to list missing debug packages
(with a view to installing manually) just lists the following:
`/usr/bin/kwin_x11`.
The monitor is attached through DisplayPort.
Journald provides the following related log entries:
