I'll let just a few words about it here. I have an unstable system after upgrading from 10.04 to 12.04. On undetermined conditions, my system abruptly logs out and it is showed to me again the login screen: no warnings, no error messages. This all happens in an instant: one second i'm working, the next one there's the login screen. After logging in again, all my work is lost, all programs were automaticaly closed. The only time-matching problem i've found in the logs is in "apport.log": recurrent unhandled exceptions at exactly the same time my system logs out.
