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.
