Twinview + PCI video = xinerama?
Im new to this forum and was wondering if anyone had any experience with twinview AND xinerama? I have a geforce4 ti4200 with Twinview that I am currently using in debian. I was wondering if it was possible to throw in a PCI video card (probably a TNT 2) and use it as a 3rd monitor for an extended desktop. If anyone has any experience and caveats in the matter that they could share, I would be very appreciative.
Also, will I lose the accelerated graphics that Ive come to enjoy with the closed source nvidia drivers in combination with xinerama and a PCI video card?
