I am seeing a lot of crashes in the i915 kernel driver in your kernel
log like:
May 28 15:54:36 nix-us2ua34705wc kernel: Call Trace:
May 28 15:54:36 nix-us2ua34705wc kernel: intel_atomic_commit+0x2b8/0x2f0 [i915]
May 28 15:54:36 nix-us2ua34705wc kernel: drm_atomic_commit+0x4a/0x50 [drm]
May 28 15:54:36 nix-us2ua34705wc kernel: drm_mode_atomic_ioctl+0x8e9/0xa00
[drm]
This suggests it might be a kernel bug.
But I also know the atomic API is only used by the Xorg modesetting
driver. You might be able to avoid the problem then by logging into
"Ubuntu on Wayland". Does that work?

Bug description:
On my system I have two display: one in landscape, and one in
portrait. The landscape display is fine, but the portrait display is
corrupted. If I unplug the display from the computer for some time and
then plug it back in it will occasionally fix the problem.
Once the problem is fixed, the display works perfectly fine,
indefinitely. However, as soon as I reboot the computer the display
will come up corrupted again and never recovers without many rounds of
plug/unplug turn off/turn on. It's extremely frustrating.
