** Description changed: - I noticed a problem last week where my GUI locked up while I was trying - to unlock it. At the time I was unable to get the system to generate a - report or find anything obvious to me in the logs, though I am no - expert. I did manage to enable some more analysis tools for next time - and it seems that next time has just occurred. + Today I tried to login to the system. The screen progressed passed the + password entry but failed to display the desktop background, the side + bar or the top bar. I left it for a few minutes while I got a coffee but + it was still in the same state when I returned. I managed to SSH in but + failed to do much else. When I tried to take a look at what was going on + with top I got a message about a Segmentation fault. I then tried ps and + the ssh session locked up. - Today I tried to login to the system.

Thinking it might - just be the GUI locked up, as it seemed to be last week, I tried to ssh - in from another machine. - - tt@172.16.20.39's password: - Welcome to Ubuntu 14.04.2 LTS (GNU/Linux 3.16.0-37-generic x86_64) - - * Documentation: https://help.ubuntu.com/ - - Last login: Fri May 1 12:46:41 2015 from 172.16.20.98 - - - tt@tt-ul-dt:~$ - tt@tt-ul-dt:~$ - tt@tt-ul-dt:~$ top - Segmentation fault - tt@tt-ul-dt:~$ ps - - As you can see, I managed to SSH in but failed to do much else.

That seemed to lock up the ssh - session. - - Next I did a quick Google to see what I might be able to do remotely to - help debug things. Nothing helpful presented itself to me so I did Ctrl - + Alt + F4 to try and get access via one of the other virtual terminal - things.
