Thanks for the reply.
I forgot to mention the link that i got the tarball from. it is:
http://sourceforge.net/projects/i855crt
When I enabled the display using this driver, I set the display on my
monitor to 1024*768 at 60Hz. Both, my LCD and the LG have the same as
their maximum supported resolution.

However, the driver doesn't require editing it to add another monitor
to the config. As to the bad display on the LG, it was unusually green
and unclear, and slightly grainy (I dont really think that matters,
because finally, I will have to modify my xorg.conf, and steer clear
of this driver) Playing around with the monitor's own
colour/contrast/brightness settings didnt work.
Somehow, there aren't too many detailed posts either in the ubuntu
forum, or anywhere else about how to edit the conf file for an 855.
How should I proceed? And if I am not looking hard enough before
asking here, please do tell me.
Thanks again for looking through. My xorg.conf and Xorg.0.log are attached.
