By any chance do some of you use Chromium 20/22? I recall that there was an issue where Chromium would free due to an ongoing problem with X11, Nvidia Drivers and Chrome's ability to use hardware acceleration.
http://code.google.com/p/chromium/issues/detail?id=145600 I experienced the same issue which is a total X11 lockup and a need to hard reset and it was entirely due to two things: a) Did not use latest Nvidia drivers from the X-SWAT PPA. b) Used Chromium and DID NOT download Chrome Official directly from Google which is maintained better, https://www.google.com/intl/en/chrome/browser/?&brand=CHMB&utm_campaign=en&utm_source=en-ha-na-us-sk&utm_medium=ha c) Used Chrome without putting the Command-line flag --disable- accelerated-compositing Please try the above steps and if the problem does not happen then it is Chromium bug #145600.. ** Bug watch added: code.google.com/p/chromium/issues #145600 http://code.google.com/p/chromium/issues/detail?id=145600 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently.
