You seem to have a very large number of packages from "origin: unknown" or from PPAs. That means they're not the Ubuntu supported software packages...

And be sure to avoid using PPAs or prerelease "proposed" updates. ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Opinion -- 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/2106722 Title: Xorg freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2106722/+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
