I think this issue is related to "compiz" I found a workaround for this issue:
When the computer freezes do the following: 1. CTRL+ALT+F1 (to get to the console) 2. login as your user. 3. sudo pkill compiz-redirector Xwindows will appear to restart but the applications running under your X will not be killed. -- 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 64bit completely freezes frequently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/993187/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
