While NVIDIA is already in the middle of working on the 280 driver series
and there's been a public beta of that, this Friday morning NVIDIA has released a new 275.xx stable release. While this release is still tagged in the 275 series, it does contain a few worthwhile fixes and new hardware enablement.
The new hardware brought up in the 275.19 driver release is just officially for the GeForce GT 540M mobile graphics processor. Fixes in this release include addressing a memory error/abort reported by glibc, an OpenGL driver bug causing an application crash, a performance problem when switching between stereo and monoscopic rendering, poor X driver handling of pixmap out-of-memory scenarios, a fix for an interrupt handling deficiency causing performance and stability problems, and VDPAU presentation queue fixes causing GPU errors and hangs (this is a bug exposed by the use of VDPAU in the Adobe Flash Player).
This latest driver for x86 Linux and x86_64 Linux can be downloaded from NVIDIA.com
