This is the closest, most recent report I could find with something which also appears kernel related
Kernel 6.5.0-27 -- works fine
Kernel 6.5.0-28 -- graphics hard-hangs - sddm never displays, vtty can't be activated
shh works, sddm and x11 processes can not be killed, reboot hangs, hard power cycle required
I see reports like this literally for years, yet seemingly no resolution. Now I'm bit, in a way suspiciously kernel version related
Common internet "use nvidia drivers" wisdom is unworkable as old nvidia hardware is not supported on 22.04
04:00.0 VGA compatible controller: NVIDIA Corporation MCP89 [GeForce 320M] (rev a2)
Again, for me, this is with 22.04, kernel 6.5.0-28
All the various combinations of nouveau flags to kernel boot which have helped reduce garbage or sddm troubles don't help.
Here's a relevant boot log:
