Return of the "Product Activation" Dialog

Thanks Illian, that did the trick. my /dev/vchiq did not have the correct permissions. Nice catch.

Try checking the actual access permissions for /dev/fb0 and /dev/vchiq. You may need to adjust the latter by doing something like

echo 'SUBSYSTEM=="vchiq",GROUP="video",MODE="0660"' > /etc/udev/rules.d/10-vchiq-permissions.rules

and double-checking that any unprivileged account used to run Mathematica is a member of the video group.
