I'm also having this issue with Linux Mint 11 64 bit (based on 11.04). This occurs w/ my Lenovo t520, intel i5 processor, integrated graphics.
It has occurred both with Chrome (stable) and Chromium. I've tried reinstalling both but there is still issues. Seems to occur when I'm using flash (using flashplugin square) but it happened once when I was just opening up the mint menu. I'm usually just on AC power and the computer is only 2 months old (I'm pretty sure the Power supply is fine). this started happening a week ago. this only occurs when I click something, usually when switching web pages or opening multiple browser windows. I have also noticed that VLC player doesn't play movies very well (lags and the progress bar freezes constantly), and also flash videos (like in youtube) sometimes show up in a blank gray screen where the video should be playing. after i refresh it's usually fine. -- 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
