It sounds like everything that uses Xorg is broken.

Are you saying that "Ubuntu on Wayland" still works?

[Daniel van Vugt (vanvugt)]

Please also attach your /var/log/Xorg*.log files

[Daniel van Vugt (vanvugt)]

And do you find any crash files in /var/crash? If so then please run:

  ubuntu-bug /var/crash/YOURFILE.crash

and tell us the resulting bug ID(s).
