Hi Anant and everybody,

Seems I managed to get some drivers working on intel d2700dc board.

I installed ubuntu 12.04.1
removed the pae kernel (left on 3.2.0-40-generic)
installed the drivers - # apt-get install cedarview-drm libva-cedarview-vaapi-driver cedarview-graphics-drivers

Now in additional drivers I have working Intel Cedarview graphics driver AND drm driver for intel GMA500 (green and pretending to work)
CPU is about 30% load when playing 1080 video through VLC and the video is smooth.

However in settings - details I get "graphic unknown".
When playing 1080 video from youtube I get really bad performance. The video is jerky and CPU load close to 100%.

I suppose there is something to be done to optimize the video some more?
I feel it is not normal to show graphic "unknown" and I am not sure why the two drivers seem activated at once.

An advise would be appreciated!
