Posted lsmod info : http://pastebin.com/Y79th67k

The right diver is loaded (gma500-gfx) but Xorg doesn't fully use it.

Backup up your Xorg.conf file and create a new one with only

Section "Device"
   Identifier "gma500_gfx"
   Driver "modesetting"

Hopefully X doesn't fallback to vesa or fbdev



Modified the XOrg.conf : made sure it has only one entry:

Section "Device"
   Identifier "gma500_gfx"
   Driver "modesetting"

on boot : xorg pointer it terminated with an error.

Looks good. The right driver is used.

Add a Screen and Monitor selection to the Xorg.conf

Section "Screen"
  Identifier "Screen0"
  Device "gma500_gfx"
  Monitor "Monitor0"

Section "Monitor"
  Identifier "Monitor0"
  VendorName "Monitor Vendor"
  ModelName "Monitor Model"

The system boots but when GDM starts i just see a blank screen..

Switch back to tty1, kill gdm and start the X server with startx

Yes i tried that and i get an error: no screens found
