Problem on Screen Resolution

You can use this newbie simple guide to fix your Screen Resolution when you are stucked on using <= 800x600.
(Assuming that you had the correct video adapter driver installed, and still resolution is stucked).

*First thing to do is backup your /etc/X11/xorg.conf file.

Code:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak
*After the backup, We will edit/replace some text on xorg.conf.

Code:

sudo gedit /etc/X11/xorg.conf
Which will pop the gedit windows with the xorg.conf file loaded and ready to be editted.
Locate ONLY the "Screen" and "Monitor" section on your xorg.conf and replace some of the text inside the section.

Blue color text are comments
Red color text the the line of code to insert

Section "Monitor" #<-This remains
Identifier "Configured Monitor" #<-This remains

#directly proceed to your "Screen" section
