-- Information about the crash:
Regularly when waking my Laptop from sleep (often, as in this case, automatic
sleep triggered by inactivity), Kwin crashes on wakeup, resulting in all
applications being terminated.
The two notable modifications to my system are some kmod based kernel modules
that I need to support my hardware and that I'm running the KWin script
Krohnkite.
I selected "Fedora RPMs" as Distribution method, but that's only half correct,
since I'm running Fedora Kinoite. Here's the output of rpm-ostree status:
fedora:fedora/42/x86_64/kinoite
