I can confirm that in a Dell XPS 17 with Nvidia GeForce GT 555M graphic card.
I had that happen three times. The first one was after installing Nvidia restricted drivers. They downloaded/installed correctly and before I could restart to complete the installation it just spontaneously logged out and I think that messed up the installation because my graphic acceleration stopped working after restarting. I don't remember what was I on the second time it happened but the third one followed this chain of events... Login Open emesene Open Chrome Close emesene Open Thunderbird Random logout But as some guys told before, is >seems< to be that happens after clicking something. Not 100% sure but probably. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/778490 Title: Random logout after upgrading to Natty Narwhal 11.04 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
