Possible stupid fix: I had the total freeze problem as well. Yesterday night, the computer froze 7 or 8 times in three hours. Today, I installed gnome 3 and used it for a few hours without problem. I installed the gnome 3 GUI following the procedure given at http://www.allili.net/gnu-linux/installer-gnome-3-4-sur-ubuntu-12-04 (in french), i.e.:
sudo add-apt-repository ppa:gnome3-team/gnome3 sudo apt-get update sudo apt-get install gnome-shell Then you need to reboot (but you must be used to rebooting by now) and select the gnome GUI at the login screen. This pseudo-fix is not as radical as installing a previous version of Ubuntu. Too sad for people who like Unity. If on the long run, it appears it really solved the problem (this bug is sometimes surprising), it may indicate the bug is rooted in one of the packages specific of Unity. I'll fill another comment if the system restarts freezing again. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently.
