How can I use a PQ Labs multitouch overlay with the Pi?

Question

I have multitouch screen overlays from PQ Labs that I would like to use with my Pi. They only have drivers for the x86 architecture.

Is there any way I can use these? If not, are there other multitouch overlays compatible with the Pi?

Answer 1

If the manufacturer provides open source linux drivers then they could be recompiled for the pi. There are a bunch of touchscreen drivers available for the raspbian kernel (src/drivers/input/touchscreen) some of which are apparently multitouch. The list is:

Obviously you then need userland software; Qt may have some support.
