I think I've found what triggers this behaviour: I have a line in /etc/rc.local to set my initial brightness to a certain point. I believe the last update to either X or LightDM causes a race condition which triggers this bug. I have now added 'sleep 2' as the first line in /etc/rc.local, and everything seems to be normal again.
Still, it might be worth looking into, as I'm most likely not the only one with such a startup script. ** Attachment added: "apport.xorg.Q2aTHn.apport" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1064878/+attachment/3392419/+files/apport.xorg.Q2aTHn.apport -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1064878 Title: After X update, tty7 is very glitchy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1064878/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
