How is your external display connected? Via a regular port or via some propietary hardware system? It seems kind of strange that adding a new screen would trigger this issue.
If you feel adventurous please install unity-2d from this ppa https://launchpad.net/~aacid/+archive/ppaprecise/ and do the following * Open a terminal * Write "killall unity-2d-shell" * Write "killall unity-2d-shell" again * Write "unity-2d-shell" * Try to reproduce the problem with alt+tab triggering the hud * Attach here the output of the "unity-2d-shell" command, which shall contain the logging of which keys you pressed/released and why the hud was triggered -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/977683 Title: alt+tab brings up the hud unwelcomed when external monitor is connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-2d/+bug/977683/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
