Issuing coredumpctl list as the user that was running the segfaulted process should show information about the core dump. Whoever debug the problem might be interested in that. root can see all the coredumps. Or so I think. u34. Yaro Kasear <yaro@marupa.net> wrote:
I seem to be having an odd issue with Xorg since updating to 1.20.9.
I tend to be logged onto Xorg across more than one user based on what kind of task I need, and switch between them via CTRL+ALT+F1/F2/F3.
Since the update this morning it seems to have started causing segfaults on Xorg the longer I'm switched away from the console containing the Xorg instance that crashes.
I am not even sure how to begin troubleshooting this problem. I can usually figure this out on my own.
Process 8780 (Xorg) of user 1003 dumped core.
