Hi there, I think this is something more "global" - I mean it affects whole system, not only part when you're going back to login window.
For example, this happens every time I connect external monitor through DP. Of course, I cannot extend desktop to this monitor. Looks like monitor is detected, bot due to mentioned error "not trained" ... A minute ago, I tried daily build as you recommend and error is still there. -- 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/1403275 Title: i915 display driver causes crash back to login window To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1403275/+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
