I've done some testing and I don't reproduce these problems in my setup. Other people have confirmed working multi-monitor behaviour.
What I see is: - If the monitor is plugged in before boot, then the greeter is shown mirrored on both monitors - If the monitor is plugged in after boot, then the greeter remains on the primary monitor, and the second monitor just shows a black background. If you're getting this problem, can you use the following PPA and attach the file /var/log/lightdm/:0-greeter.log (or /var/log/lightdm/x-0-greeter.log for newer versions of lightdm). https://launchpad.net/~robert-ancell/+archive/unity-greeter Thanks -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/813566 Title: Greeter not displayed correctly on multi monitor setup To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/813566/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
