Whenever I try to shutdown my system, it just ends up stuck on a black screen with a blinking cursor in the top left.
I'm running Ubuntu 20.04 LTS.
I have done a fresh install of Ubuntu twice with no effect.
In the terminal 'journalctl -rb -1' shows that last night after shutdown it ended on
Jan 27 22:18:01 moz systemd-journald[304]: Journal stopped
and then stayed on the black screen with top left flashing cursor until the morning when I forced it to shutdown by holding the power button which was at 0900. So it looks like shutdown was complete? If not why did the journal stop last night and not this morning?
Here's the full log from 'journal -rb -1':
