Reproducible on 14.04.1. Indeed it has to do with the max total display size in 3d mode: "Requested size (2304, 800) exceeds 3D hardware limit (2048, 2048). You must either rearrange the displays so that they fit within a (2048, 2048) square."
Solution: - Drag the extra monitor *under* the laptop monitor - select laptop monitor and then external monitor again (this reinitializes the dropdown box for screen orientation) - pick orientation 'normal'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/983291 Title: Screen Rotation options only Counterclockwise & Clockwise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/983291/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
