Thanks for the bug report. I can't yet see any cause for the freezes. Next time it happens please:
1. Note the exact time and date of the freeze. 2. Reboot. 3. Run: journalctl -b-1 > prevboot.txt 4. Attach the resulting text file here along with a note telling us the exact time and date of the freeze. 5. Check /var/crash for crash files. ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: 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/2054121 Title: Random Freezing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2054121/+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
