I have downgraded xserver-xorg-core and xserver-common but the problem persists. I have also managed to downgrade libimobiledevice2 and libdvdread4 but all the kerberos stuff is blocked for downgrade by Bug 878263.
The logs mean nothing to me. Isn't there anything in the Xorg logs? Whatever is the cause it has permanently broken my system! ** Changed in: xorg-server (Ubuntu) Status: Incomplete => New -- 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/878235 Title: System unusable after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/878235/+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
