Thanks a lot for your response! I know about that, but then I still can't touch the screen, can I?

One possible solution I could think of is to call the selection binary via ssh-X-forwarding. But since I'm planning to use the modem away from my home wifi, I won't be able to do that every time, or it would be a huge pita...

I hope that there is some /proc or d-bus switch that controls the different modes?
