Quoting venkat (venkat.s@vortexindia.co.in):

Tried various options today and finally modified xorg.conf with below settings
made my X server start with multiple displays enabled.

Section "Device"
   Identifier "Intel GMA3600"
   Driver "modesetting"
   BusID "PCI: 0: 2: 0
   Option "Monitor-DVI-0" "DVI screen"
   Option "Monitor-VGA-0" "VGA screen"
Section "Monitor"
   Identifier "DVI screen"
Section "Monitor"
   Identifier "VGA screen"


However, i notice that the display is not smooth. Even, when i traverse to from
one menu to other i see it so shaky. Right now fighting to fix that.
  Need some guidance

I typed   gma3600 jerky   into google. The second hit contains:

"The new D2700 does have integrated HD video encoding and it works as
promised for the most part. Both 720p and 1080p HD video can be played
as long as its either MPEG2 or H.264, although 1080p can be a bit
jerky at times. It's not a slideshow, but it's also not completely
smooth. Especially when the bitrate is a bit higher, it starts to
struggle. This likely has to do with Intel's GMA3600 video drivers
that the manufacturer has been struggling with since launching the new
Atom platform in late 2011."

I know nothing about this hardware but I know a man who does. :)

On my old Thinkpad, I had to reduce the color depth in xorg.conf. Worked a charm. Ric

Tried 16 , 24 and different depths randomly depth still i see no improvements in display. Still, the display transition is so jittery. My target application is a simple GTK application. For sure does not require any 3d. All I need is dual display.
