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?
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 (
Obviously you then need userland software; Qt may have some support.
Without the correct driver you get basic mouse support, but beware it becomes totally useless once you start using several fingers. It simply stops responding, so it's totally unreliable in that way.
In my experience, the drivers @goldilocks suggested will not work at all. I have tried several panels in different versions and sizes. I've exchanged emails with some chinese guys they provide as support contact.
What i've found is that there is an opensource driver, they provide it and even annouce it on their site. Also there is a more up to date version, but it is delivered only to confirmed customers. With few minor changes, I managed to build that one on the Pi, but unfortunatly it won't recognize the panel. I tried with several kernel versions and all i get is either unrecognizable panels or kernel panics. I have the feeling this is about some power issues or some sort of non-standard electronics or protocols. This is odd because they officially support Android.
Latest news i got from tech support (1~2 months ago) is that the new versions of the panels are standard HID and work flawlessly as a single touch mouse without any driver, just plug & play. But you have to be lucky as there are a lot of old panels on stock and you simply cannot ask to be served the recent ones. Anyway, for me, i need multitouch support, so it's not enough.
Im very interested in getting them to work, i can provide the latest opensource drivers and even remote ssh if any kernel-expert wants to dig.
