I am running 12.04 on a Dell 5430 laptop with external Dell monitor as a real newbie. My monitor is running at 1152x864 rather than the 1920x1080 that is capable of.

I have followed the various posts and, using xrandr, have set the resolution to 1920x1080 successfully. To make it persistent different posts suggest updating /etc/x11/xorg.conf or /etc/gdm/init/default or /etc/kde4/kdm/init/default. However I cannot find any of those files in /etc.

Where do I add a new modeline to make the resolution change persistent?
