Server crashes when Using X11 desktop instead of Wayland

[Greg Hughes]

Having trouble with the collection tools with no desktop after the crash. This is a KVM Virtual machine using QXL video.

Changed WaylandEnable=false in /etc/gdm3/custom.conf

Expected the system to boot to the greeter. Looks like GDM tried three times to start the X server and gave up. Used VT 2 to get a console login

Problem seems to be an assert in DRI initialization:
