I hit this bug today on vivid overlay PPA. My laptop was not booting anymore. I was adviced to reinstall the older xserver-xorg-core (1.17.1-0ubuntu3) and that fixed it.
The overlay ppa currently offers: xserver-xorg-core ---> 1.17.2-1ubuntu0.1~overlay1 (and this is the version causing issues) xserver-xorg-video-intel ----> 2:2.99.917-1~exp1ubuntu2.2 (and this version doesn't seem to contain the fix) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1462994 Title: 2:1.17.1-0ubuntu4 broke xmir ABI To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1462994/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
