Nvidia Driver 340.58 Released, How to Install it in Ubuntu 14.04

Nvidia 340.58 PPA

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.
