I am using a system76 computer. I have been running Ubuntu 20.04 for some time fine.
Last night I upgraded to 22.04 after I was prompted to do so.
But now when I try to log in, I can only do so into a bash shell. I can't get the windowing system to start from there. I have tried startx and other things that I have found on various sites where it seems others had a similar problem.
I tried chmod 755 /tmp /etc/tmp, I tried uninstalling and reinstalling Xorg, I tried deleting .Xauthority. All of which I found recommended in various places.
When I type startx from the bash shell prompt, I get the following error messages:
(EE)
Fatal server error:
(EE) Could not create lock file in /tmp/.tXO-lock

Please consult The X.Org Foundation support

for help.

xinit: server error
Can anybody help me?
