Among the many new features for Fedora 11, a newly added one is Nouveau becoming the default driver for Nvidia cards in Rawhide. Nouveau is an effort to create a completely free and open source 3D driver for Nvidia cards. Fedora 7 originally included this driver installed but not enabled by default. Red Hat recently hired Ben Skeggs, one of the primary Nouveau developers and Nouveau driver has been accepted by the Fedora Engineering team to be the default driver for Nvidia cards with the legacy nv driver as a fallback option. Nouvaeu already supports more chipsets, RANR 1.1 support, Accelerated XRENDER, Textured Video support for many cards that are not covered by the nv driver which has been hampered by a lot of obfuscated code as well. Phoronix has other details.
