The Atom N2600 uses an Intel GMA 3600, an integrated video adapter based on the PowerVR SGX 545
graphics core.
At the moment Intel has no 64-bit driver for Xorg. However you can get basic support with the fbdev framebuffer
video driver. To get Xorg to use the right DPI settings for the 10.1" display, I put the specifications on the
physical size of the screen in the Xorg configuration file so that the proper DPI is calculated.

Fot the ETPS/2 Elantech touchpad, the psmouse module must be loaded with the proto=auto parameter. You also have to enable the tap-to-click
and the vertical edge scrolling in the synaptics config.

Playing video
To play video in X, I had to set my mediaplayers to use x11 video output. I also set the decoding threads to 4 to
utilize the maximum power of the Atom CPU to decode video. This way I can play fullscreen HD movies with my GMA 3600 in smplayer and VLC.
