Comment 56 for bug 1132584

I have had a similar issue with this netbook: Samsung NT-N100S-E31S, which seems the Korean version of this one:

Again, Intel Atom N2100 with GMA3150 graphic chipset.

I have installed xubuntu 12.04.1 i386:

By default everything works fine except video playing. Running 'xvinfo' shows:
X-Video Extension version 2.2
screen #0
 no adaptors present

Ctrl+Alt+F1 and install the following packages from the tty:
sudo apt-get install xserver-xorg-lts-precise
sudo apt-get install cedarview-drm cedarview-graphics-drivers libva-cedarview-vaapi-driver
sudo apt-get install libva-glx1 libva-tpi1 vainfo libva-dev

And now, this very important step: replace lightdm with gdm.
sudo apt-get install gdm

In this case, adding video=LVDS-1:d to Grub results in a black screen after init scripts.
So in my /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT=""

sudo update-grub

After that I succesfully I ran apt-get update and everthing keeps working fine.
Kernel is 3.2.0-60-generic
