Bug Description
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.
I was able to enter my username and password at a vt 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.

Out of the many error report windows that popped up, only 1 suggested it was not this bug. I raised https:/ /bugs.launchpad .net/ubuntu/ +source/ linux-lts- utopic/ +bug/1453033 as a result, in case it has any extra debug information in it.
Looking over the how to triage page, I can see that checking the memory of the machine is one of the first things that I should do. I have now created a bootable USB stick that should work with my system. I will try and kick off a memory test later today and report the results on Monday.
