If something crashed, we need a backtrace of it so we can figure out what's going on. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports Can you please attach one? Thanks!

Sadly I can't figure out how to get a backtrace on my system since I don't get the error pop-up when the crash happens. It simply takes me straight back to the login screen. I did notices that it displays some error messages on the screen right before showing the login screen though, so I've uploaded a quick video of that. The error messages should be readable. https://youtu.be/8ZNDS-n4Aug If there is any info on how I can access the backtraces? Since all my running apps get killed, I imagine that GDB would be taken down with it, so the advice in the linked article desn't really help. You may be able to retrieve a backtrace using `coredumpctl`. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl This strikes me as likely to ultimately be caused by an issue in the graphics drivers or the kernel, though.

It looks like basically everything crashed over the course of 3 seconds or so, due to a combination of SIGABRT and SIGSEGV errors. The first program to crash is Xorg, then 5 instances of drkonqi, a bunch of other random apps, and then near the end kwin_x11. All of them have an accessible corefile except for Xorg (which is marked as inaccessible). Should I try installing a few more debug symbols to try to get more info on Xorg in particular, since it appears to be the first program to crash (although if it's a kernel issue, I'm not sure if it would appear in this list?). Yes please. If Xorg itself is crashing though, it's very likely an Xorg issue or a kernel issue, not a KDE issue.
