I want to attach a touchscreen to my Raspberry Pi. While doing some internet search about this, I found out that this is not trivial, because not all touchscreens are compatible.

How do I find out, whether a touchscreen is compatible to the Raspberry Pi?

I am not looking for recommendations or lists of possible devices, I want to know how to find out, if a given screen works.

The issue is going to be drivers. As most products sold do not have open source drivers, it is up to someone with the know how to reverse engineer them. Because of this, if the device is not extremely popular, it is likely not going to be supported.

I have not used one of these personally but sites do exist with hardware databases. The accuracy of the database to your specific nix build is questionable and as the lists are typically user built so you can only trust them to a certain extent.

There are some Videos on youtube how to add touch screen to different Linux computers, they would be a good source of what has support. De supported ones should be able to connect to USB-ports. So a look in touch screen drivers and which USB devices they support would be a good source. – Anders Jun 28 '12 at 0:23
Just make sure I'm understanding this post, ARM vs x86 vs x86-64 don't have their own compatibility lists, so the general lists are a better resource. Nor is there a RPi-specific list anywhere. Correct? – Zoot Jul 2 '12 at 18:32
I would say these days most products do have OSS drivers (integrated in systems, not vendor drivers). Ones that don't are getting fewer. It was the other way around in the 90's. Certain classes are more likely to work than others. – XTL Sep 6 '12 at 10:21

Lilliput sell some HDMI touchscreens and there is some evidence that it works with the RPi.

USB would be the instant choice.

Converting an Arduino touchscreen to use the GPIO port would be a simple project.

Or wait for the DSI drivers/information to be released.

Current Development is being put into the DSI camera port, not the display+touchscreen.

If I was not so poor then like above, a HDMI 1.4 screen with touch interface.
