Update: I downgraded back to 13.04 and the problem vanished, thus confirming that one of the upgraded packages is causing it. However, I am still running the 3.11.0-7-generic kernel, so it's something else.
One way to uncover the culprit would be to update to 13.10 incrementally just a few packages at a time and see which one brings back the freezes. I don't have much time these next few days but if somebody could try it, it would save all of us a lot of pain (really can't work like this). I will have a go at it next week. I don't see any other solution unless someone finally finds an error message in a log somewhere. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1184451 Title: Ubuntu 13.10 random screen freeze while Normal OS activites To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1184451/+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
