change display resolution? 800x600-->1024x768

[Charles Read <debianlist@charlesread.com>]

Hey everybody!

Kind of simple question here... how do I change the resolution that my 
new Debian system displays in?  I know I selected 1024x768 during 
install but during the boot process, login screen and in the graphical 
desktop everything is in 800x600 with about 3 inches of black screen 
surrounding the image on all sides.  How can I change this to 1024x768 
and thus cover the entire screen (as my monitor is 1024x768)?  I tried 
doing it through the Control Center in KDE but 1024x768 was not listed 
as a choice...

Thanks bunches!
