While it's not part of the NVIDIA 310
or even the latest NVIDIA 313
driver series, this morning was marked by the release of the 304.84 certified Linux graphics driver.
For those conservative Linux desktop users, the NVIDIA 304.84 "certified" Linux graphics driver now available.
Changes to the NVIDIA 304.84 Linux driver include fixing a rendering corruption issue after an X Server generation, an X Server crash when doing a RandR 1.0 rotation, support for X.Org Server 1.14 ABI, font rendering performance and corruption issues, a potential X Server crash relating to TV connectors, and a new "UseHotplugEvents" X conifguration option. The UseHotplugsEvents xorg.conf option is for supressing RandR events when adding/removing non-DisplayPort displays.
