I had the same error. To fix this I installed ubuntu in new partition, and copied the below files from xorg 7.4+3ubuntu7, then everything was ok with the old partition.
/etc/gdm/failsafeXinit /etc/gdm/failsafeXServer Attached is the log file when it failed. ** Attachment added: "Xorg.failsafe.log.old" http://launchpadlibrarian.net/36420338/Xorg.failsafe.log.old -- Garbled screen after updating x11-common https://bugs.launchpad.net/bugs/490922 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
