Multiple graphics cards


Can anyone tell me if its pssible to have a PCI bus graphics card apart from a AGP us graphics card working on one machine? I heard this is possible but have not tried it myself. Also is there any OpenGL call to specify which graphics card to use in this case?

Yes, I have run a PNY MX420 PCI along a Geforce4 Ti4600 in the same box at the same time. Look at the sample XF86Config-4 file for details on configuration. For display selection within X, simply set the DISPLAY environment variable. For example, setting DISPLAY to :0.0 will cause applications to run on the AGP card while setting DISPLAY to :0.1 will cause applications to appear on the PCI card’s display.
