desktop display and the monitor size

Hello all. NOOB here. I just installed Suse 10.0 on a Dell Inspiron 4100 laptop with a GeForece2Go video card in it. Everything installed fine but my desktop only takes up an area of about 6 inches by 6 inches on my monitor. I went into the System config and tried to change display size in the X server but when I click on the "size" buttons nothing happens. What am I missing. If you need more info please tell me. ----- iConan Before you criticize someone, you should walk a mile in their shoes. That way, when you criticize them, you're a mile away and you have their shoes.
