I downgraded xorg-server-core to 2:1.10.4-1ubuntu4.2 and then pinned it back. Everything works well now, but obviously this needs to be fixed. Here's the steps for anyone else experiencing this problem. Install aptitude if you don't already have it.
aptitude install xserver-xorg-core=2:1.10.4-1ubuntu4.2 Open /etc/apt/preferences and add to the end of it: Package: xserver-xorg-core Pin: version 2:1.10.4-1ubuntu4.2 Pin-Priority: 700 -- 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/927854 Title: X server segfaults on pointer movement To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/927854/+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
