[afnog] Increasing Screen Resolution on Ubuntu

[Tracy Musaza]

Hello Benjamin and Oluwaseun,
 
if I remember Since version 9.04 or 9.10 of Ubuntu, the Xorg don't create the default xorg.org .
 
Just relaxe ,  take a cup of milk and create an empty /etc/X11/xorg.conf  and copy this in side using your favorite editor ( vi in my vase, gnome-edit , joe or vim can make it right !!).

Dear All,

I installed Ubuntu 10.04 on my laptop. Everything worked except the monitor display which defaulted to 800x600 (not good). I need something like 1280x800

After searching google, and trying all suggested comments 
"http://idyllictux.wordpress.com/2010/04/26/lucidubuntu-10-04-high-resolution-plymouth-virtual-terminal-for-atinvidia-cards-with-proprietaryrestricted-driver/", it still did not work

I have attached my dmesg file so that someone with an idea on how to fix this could help.

Best regards,

Benjamin
