Second monitor is some "TG" a Korean monitor and I am connecting it to my Notebook VGA port. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to metacity in Ubuntu. https://bugs.launchpad.net/bugs/561294 Title: Not a helpful or appropiate error message displayed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/metacity/+bug/561294/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
