Has been running just fine, I did try using the pi it's HDD is connected to for other purpose recenly now when I try to open Ubuntu I get the desktop login When I click my username and put in my passwork after checking it is correct, goes away as if it right but then a black screen and comes back to the login again.
I did try CTRL+ALT+F4 goes into a terminal login but comes back and says incorrect password.
From a remote terminal I am able to ssh to the machine and login correctly.
Suggestions please.
