Nvidia GeForce4 card in a Dell laptop

[Margaret_Doll <Margaret_Doll@xxxxxxxxx>]

 We just installed RH 9.0 on a dell laptop with a Nvidia GeForce4
video card.  We took the suggestions for video from the installation
program.   We ended up with a system whose window just takes up
the middle third of the available screen.  All the terminal windows
that open up take up the entire system window.  Nothing is created
in the black two thirds of the screen surrounding the system window.

How do we extend the system window to take up the entire available
screen?
