Hi All,

Newbie to ubuntu and linux in general..:P
My desktop is as title and I've tried the two
most popular How-To's. They both didn't work for me.
The nVidia driver is succesfully installed, and
Below are my xorg.conf after being edited according
to the How-To's: bolded part is my edit.

After reboot, the right screen is working properly with the nVidia logo
visible.
But the left one is completely dark. The official weblink for the left one
is
here:http://www.lge.com/products/model/detail/l1917s_1_6.jhtml

I don't know if tuning resolution would help but the max reso I could get
from the system preference is 1280x1024 instead of the double size said in
the How-To's.

I have tried almost everything on the net by even installed core for k7 but
it still wouldn't work. Any idea is appreciated.
