Thanks for the bug report. I can see two possible problems here that
might relate to screen flicker:

* The i915 kernel driver crashed, in intel_modeset_init

* Xorg is using probably the wrong driver 'intel'. It should be using
the modesetting driver on a modern system like yours. Please try
removing that wrong driver:

  sudo apt remove xserver-xorg-video-intel

or just try logging into "Ubuntu on Wayland" instead.

Maybe it's some combination of the above two issues.
