-- Information about the crash:
Relatively often (but not always), when waking the display up after having gone
to sleep and locking, a message appears indicating that the lock screen has
crashed and I have to log in from a terminal to unlock the session. The
computer itself did not go to seeep, only the displays. My setup is two high
refresh displays (138hz and 120hz) on a secondary video card (the primary being
reserved by vfio-pci for allocation to virtual machines): a 4k monitor and a 2k
monitor, with the 4k being the primary. I did not encounter this issue with KDE
6.0. Happy to provide further information as needed.
The crash can be reproduced sometimes.
