I am also experiencing random complete freezes on a fresh install of Ubuntu 12.04 LTS.
Ivy bridge 3570k 3.4 GHz MSI Z77A-G45 16 GB DDR3-1600y 240 GB SanDisk Extreme SSD 2 TB Hitachi Hard Disk Onboard HD4000 Graphics Unity-3D, Unity-2D, Gnome-shell, and Gnome classic with effects all randomly freeze the computer with no mouse movement possible. Forced reboot always ends up with a notification of it having to run in low graphics mode. I restart from terminal and then I get the standard login screen. Interestingly enough, I can run Gnome classic without effects and I haven't experience any random freezes as yet. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
