As mentioned in bug https://bugs.launchpad.net/ubuntu/+source/mouseemu/+bug/120102/comments/6 I really think mouseemu should not be installed by default on machines it is not needed on - see rydberg's comment above https://bugs.launchpad.net/ubuntu/+source/mouseemu/+bug/251830/comments/19 - since this breaks a bunch of stuff as mentioned in this bug, and also remaps F11 and F12 which is completely unintuitive and broken.
