Changing resolutions

[thekrebster]

I'm running Mandrake 8.2 with a Creative Blaster Riva TNT2 Ultra and have succesfully installed the latest Nvidia drivers. OpenGl is working fine, but since I'm running the desktop on 1280X1024 resolution, when I start an OpenGL game or app, it uses that same resolution, resulting in somewhat slow framerates.
If I try to use the configuration manager to change the resolution, it changes the XF86Config file, and the Nvidia drivers are not loaded.
How do I change the resolution without changing the configuration file?

Just edit /etc/X11/XF86Config-4 and add additional resolutions to the Display Subsections inside Screen.

The first one in each is what X will use by default.
