I don't think I have this problem here but I'd need to emerge a
specific game that runs full screen to test. Could you please provide
the name of something easy to emerge and test. I ran a game called 0ad
a couple of months ago and I was able to make it full screen on one
monitor at that time.

Also, whereas I think you have two monitors, I have 3 hooked to 2
_different_ Nvidia cards. (a GTX465 driving 2 monitors and an 8400GS
driving 1) Since installing the second VGA _none_ of the KDE OpenGL
effects have worked. However a friend has two 8400GS cards installed
driving 3 monitors and OpenGL works fine for him on all 3 monitors so
I figure that's an Nvidia driver issue when the cards are different
types.

Anyway, I'm attaching my xorg.conf file in case there's something of
value there for you. I don't claim it's a very good xorg.conf file but
it seems to mostly work for this machine.

Please trim responses.

HTH,
Mark
