Server aborting + + + [Original Report] + I was running several programs on unity desktop 5 on Ubuntu 12.04 (updated to 15.1.2012), also package installations. There happends a automatically session logout , which I have not introduced, out of nothing. I came back to the Ubuntu startslash for logging in automatically. A login in a unity session brings a new session on. The gnome-system-monitor is still showing the programs running from the privious session, but I could not access them from my new logging in. So the old session seems to be running anywhere and anyhow. - That's a very bad behaviour. I have not saved my work and no chance to enter the running processes for that anymore, so dataloose is the consequence. - As special add: Package installation has not finished it's work, or better: I be not sure that it has done all installations with success. + As special add: Package installation has not finished it's work, or better: I be not sure that it has done all installations with success. Because I have had not made any updates/upgrades with this run I am optimistic that a newstart of the system does not break boot abilities, but think of this during an update/upgrade. -> The system may become broken. I see this as critical bug. Because of not knowing what happens exactly I have filed this against unity v5 with apport call, so you have all logs which gathered by apport. When you have the need for further logs or doings, tell me.
