Hello.
I use Redhat linux 7.3.(I have to use RH 7.3 at office because of some
proprietary application which only work on RH 7.3)
When I use mplayer or some games(lbreak2, ltris and so on..), full
screen mode does not work.
I just can see small movie/game screen with black background.

How to configure XFree86 for full screen mode Mplayer or games?

My XF86Config-4 File's contents.
