I am running SuSE-based embedded system with a touchscreen. The embedded application is a graphics application which uses OpenGL over X Window for graphics. We have a user-space touchscreen driver that reads the touch events and calls our callbacks. These callbacks simply forward the x,y events to the application.
We are refactoring the design and thinking to read touch input events through X11.
Can anyone tell me how to enable touchscreen for X11? How do I know if my touchscreen is supported by X11? If not, how to do it?
