Title:
Tried to login, GUI locked up. Did reboot & was presented with
several messages : general protection fault: 0000 [#31] SMP
Status in linux package in Ubuntu:
Incomplete
Bug description:
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. Thinking
it might just be the GUI locked up, as it seemed to be last week, I
tried to ssh in from another machine.

Welcome to Ubuntu 14.04.2 LTS (GNU/Linux 3.16.0-37-generic x86_64)

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. 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 thinking that might be a
simpler program and able to show me something. 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. I was able to enter my username and password but as
soon as I had done so I seemed to get some sort of log trace on the
screen. It mentioned the USB mouse I had being connected. I was not
able to enter any commands so instead I tried unplugging and
reconnecting the USB memory stick I had. I could see it registering
in the trace. I did the same with a USB temperature probe and could
see it connect too.
After that I figured a clean shutdown was about the best I could do.
I found http://askubuntu.com/questions/53263/shut-down-computer-from-
keyboard and started the Alt + SysRq + r, e, i, s, u, o. The first
two of three keys reported that they were disabled but after that it
seemed to work.
After the shutdown, I left the machine till 09:01 and powered it on
again. It booted, I logged in and was then presented with several
"System program problem detected" messages. I am now trying to work
through them in the sequence they were presented.
