The NVIDIA 173.14.75 legacy driver released provides X.Org Server 1.8 support so that those customers with GeForce 5 (FX) graphics cards can continue using the proprietary driver for 3D/OpenGL and XvMC video acceleration support when they update their X Server when updating their distributions. The other NVIDIA 96.43.18 legacy update provided some bug-fixes, but went without any server 1.8 support. NVIDIA though will be updating the 96.xx.xx driver in the future with this updated X.Org support.
NVIDIA's Andy Ritger wrote to us, "Yes, we will eventually add xserver 1.8 support to the 96.xx.xx series. We do not plan to backport new X server support to the 71.xx.xx series." In other words, it's basically the end of the line for the NVIDIA 71.xx.xx Linux legacy driver.
This is the driver for any customers with GeForce 3, GeForce 256, TNT / TNT2, Riva 128, Vanta, and Quadro 2 Pro graphics cards. This NVIDIA hardware is quite old so it shouldn't affect too many people, but those running such vintage hardware will have the only choice of switching over to using the Nouveau graphics driver stack when updating their X.Org Server or Linux distribution. Those with GeForce 2 Go, GeForce 4 MX, GeForce 4 Go, and GeForce 4 Ti graphics cards still should be getting this new support within the 96.xx.xx driver, but you may have to wait a while.
