If the cursor still moves then Xorg is working. The rest of the screen is from gnome-shell/mutter so that's where this bug should be assigned.

Though comment #2 shows the amdgpu kernel driver crashing in the Xorg process. I think that's probably a separate bug.

To separate these issues, please check /var/crash for any crash files and use 'ubuntu-bug' to create new bugs for any of those if they exist.

I will now make this bug about the kernel freeze in comment #2.

It seems to be a recurring pattern in recent months that the amdgpu driver crashes or freezes in the kernel:
