Hi Norman,
That magic spell seems only to worked for a few seconds(<20) until the mouse/display stopped, while genode still received the mouse events, I saw it from the printfs.
Due to many changes in my new dev box, I installed Mint 17 Cinnamon in another partition, then only build genode 14.08, I got the same results.
I know 14.05 and 14.08 worked on my old Mint Mate, so I installed the new Mint 17 Mate, and then 14.08 demo ran beautifully without any other changes, it uses qemu-2.0 and locale=en_US.UTF-8.
By the way, the other test runfiles without the qemu gui worked just fine in Cinnamon/qemu20/genode1408 setup.
I'll check it out why 14.08 demo does not work on setup while 14.05 works, my wild guess it hit something on gnome3(Cinnamon), because it's ok on gnome2(Mate).
