Thank you for taking the time to report this bug and helping to make Ubuntu better. Please run the command 'apport-collect 839774' which will attach necessary information for debugging this as an Xorg problem.
If you could add more information about the freeze that would be great, like if you can move your mouse, switch to a VT (Ctrl+Alt+F1) or even if you can ssh into the machine. Thanks in advance. ** Package changed: ubuntu => xorg (Ubuntu) ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- 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/839774 Title: System frozen randomly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/839774/+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
