Nvidia Graphics Driver for Linux has just released version 340.58 with new GPUs support and a few bug fixes.

The latest long lived branch release Nvidia 340.58 was released this Wednesday with below changes:

• Added support for the following GPUs:
  • GeForce GT820M
  • GeForce GTX 760A
  • GeForce GTX 850A
  • GeForce 810A
  • GeForce 820A
  • GeForce 840A
• Fixed a bug that could cause VT-switching to fail following a suspend, resume, and driver reload sequence.
• Fixed a bug that caused incorrect colors to be displayed on X screens running at depth 8 on some GPUs.
• Fixed a bug that prevented GPUs from being correctly recognized in MetaMode strings when identified by UUID.
• Implemented support for disabling indirect GLX context creation using the -iglx option available on X.Org server release 1.16 and newer.  Note that future X.Org server releases may make the -iglx option the default. To re-enable support for indirect GLX on such servers, use the +iglx option.
• Added the “AllowIndirectGLXProtocol” X config option. This option can be used to disallow use of GLX protocol. See “Appendix B. X Config Options” in the README for more details.
