Public bug reported: I would be happy to try to acquire more information to help track this problem down but I do not know what to do on my own so I would need directions.
This problem first started occurring after I upgraded to 15.10 and has been happening once every few days since then. The system will without warning crash to a console-looking screen which shows some of the typical startup screen notifications about different services coming up etc. The system automatically then goes back to the login screen after about 10 seconds without user intervention. I log in and it seems that everything works fine but anything I was working on is lost and there is an error notification waiting for me.
