I think this was mentioned in another thread but "LEDs" are the little ones next to the ring and OLEDs are the ones that can display pretty pictures. I don't really have a good idea on the OLED approach yet. From a driver's POV the best approach may be to set a property to a Pixmap, with the driver the converting to the actual format the kernel wants. There are plenty of tools that can convert from $FILEFORMAT to pixmap, and IIRC we had a xsetwacom patch for this at some point. > - can wacom provide a library of pixmaps for us to use for the LEDs, so > that they look like they already do on Windows or MacOS X, or would we > have the time consuming task of re-doing them?
