I have no trouble with orthogonal OpenGL rendering, but whenever I add a perspective function, I get a blank screen. The program apparently works on other computers.
I have the latest graphics driver for my card. I also ran GLsetup and tried the one it downloaded, even though it said my present graphics driver is newer than the one it downloaded.
I have a built-in graphics card that uses the Intel 810 chipset.
Any ideas why this might be happening, and what I can do, besides buying a new card?
