Title:
XORG crashes with segfault on Ubuntu 1804 during login
Status in xorg-server package in Ubuntu:
Expired
Bug description:
This is maybe a long shot, but I have a Dell XPS 13 2020 running
Ubuntu 18.04. It was running fine for a while, but for some reason it
recently developed an issue where xorg crashes on login. I get as far
as the desktop, but then it locks up and mouse/keyboard stop
responding.
I have verified this happens if I select the following login shells:
Ubuntu, Gnome Classic, xfce4. It does not happen under wayland, so I
have switched to that for now.
The segfault is as follows:

I have attached the Xorg log file, if that is helpful. Are there any
steps I can take to debug?
Thanks.
