So I'm affected too. On a Dell Inspiron 640m with Intel hardware (processor/chipset/video). Seems to happen most while using Chrome, on Natty 64 bit. It happens completely irregularly and is not reproducable until now. It happens mostly when I'm using a lot programs at the same time.
The strange thing however, is that it only happened on my own profile. The laptop is in use by my wife and childern, with different logins, but they are not complaining - and I really would hear their complaints! -- 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
