This first stable 275.xx Linux driver is coming after the release of the 275.09 beta, which brought support for new GLX protocol extensions, bug-fixes, VDPAU improvements, hardware-button-based pairing with NVIDIA 3D Vision Pro, and other changes. Also last week was the release of the 275.09.04 pre-release, which introduced GL_EXT_x11_sync_object support.
The NVIDIA 275.09.07 driver is now deemed stable with these changes, plus it also tacks on hardware support for the following new products: GeForce GTX 560, GeForce GT 545, GeForce GTX 560M, GeForce 410M, GeForce 320M, GeForce 315M, Quadro 5010M, Quadro 3000M, and Quadro 4000M. This new release also fixes a bug that had caused desktop corruption from the GNOME 3.0 desktop when performing a VT switch or doing a suspend-and-resume cycle.
This new binary NVIDIA Linux driver can be downloaded from the NVIDIA FTP server.
