I'm having a similar problem with the unity desktop and xinerama. I have a dual-monitor setup, each one running of a separate 550ti; my secondary monitor is left of center.
When I move the mouse pointer from the left of center monitor, onto my center screen, the pointer jumps all the way to the right side of the center monitor. it also has a momentary hang (like its hitting resistance) when I'm moving it across an invisible vertical line 2" in from the right side of the center monitor. Neither of these problems occur in any of the gnome desktops, and the "invisible line" goes away if I turn off the second monitor. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/999962 Title: Mouse jumps to other screen when trying to activate launcher with auto-hide launcher enabled on multi-monitor setup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/999962/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
