  • Fixed a bug that caused Xid errors when using stereo mode 12 (HDMI 3D) on Quadro boards without an onboard stereo DIN connector.
  • Fixed a video corruption issue for VDPAU decoding of VC-1 and WMV video streams utilizing range remapping on Maxwell GPUs.
  • Fixed a “black window” bug in Ubuntu 14.04 when using the Xinerama and Composite extensions.
  • Fixed a bug that caused the screen’s contents to be shifted downward when a G-SYNC monitor is unplugged and replaced by a non-G-SYNC monitor.
  • Fixed a bug that prevented G-SYNC from working when a G-SYNC monitor was unplugged and plugged back in without a modeset.

  1. Can I install it on Ubuntu 12.04?
    When I try install with PPA: “package is not found”.

    • The PPA does not provides this driver for Ubuntu 12.04, but you can follow the link (in the bottom of post) to install it manually from the official package

  2. I installed 340.32 and the driver manager on detects it. However, it didn’t install with Nvidia settings so I installed that myself. However, all I got were the “Application Profiles” and “nvidia-settings Configuration” tabs. Did something go wrong with the installation?
