X and Fluxbox :: Custom Resolutions?



I'm new to DSL, and would like to know how to create a custom resolution for use on my laptop screen (1920x1200), if possible. Im booting from a USB Stick if it matters...Any help is appreciated  :D
I also have this problem. I have a 7800 GTX and I'd like to run it in native resolution (also 1920x1200). I've tinkered with the XFree86 package and the nvidia drivers, but haven't had much luck.

There may be some framebuffer modes available for you to use that are non-standard. The methos described at the foot of the above page will show you what they are.
