I just picked up a Fujitsu U820 UMPC and installed Intrepid on it. Everything generally works out of the box (although I have not yet tested the CF and SD slots or the integrated GPS). Video (based on Intel's new GMA 500 controller) works with the vesa driver but doesn't go above 1024x600 (the LCD's native resolution is 1280x800) and there's no 2D/3D acceleration. Does anyone know where I can get an accelerated display driver for Linux for the GMA500?
