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?
