Nvidia 340.46 PPA

The latest NVIDIA Linux driver has reached 340.46 with a few bug fixes. Here’s how to easily install it in Ubuntu 14.10 or Ubuntu 14.04 via PPA repository.

What’s new in NVIDIA 340.46:

  • Fixed an OpenGL issue that could cause glReadPixels() operations to be improperly clipped when resizing composited application windows, potentially leading to momentary X freezes.

  • Fixed a bug that could prevent the GLSL compiler from correctly evaluating some expressions when compiling shaders.

  • Fixed a bug that could cause nvidia-installer to crash while attempting to run nvidia-xconfig on systems where that utility is missing.

  • Added option UseSysmemPixmapAccel to control the use of GPU acceleration for X drawing operations on pixmaps allocated in system memory.

Release note and supported GPUs are available in the Nvidia page.

Install Nvidia 340.46 via PPA:

Besides using the official installer, we can easily install the driver from a Launchpad PPA.

To add the PPA & install Nvidia 340.46, press Ctrl+Alt+T to open terminal. When it opens, run the commands below one by one:

sudo add-apt-repository ppa:graphics-drivers/ppa

sudo apt-get update

sudo apt-get install nvidia-340


When done, restart your computer.

If for some reason the driver does not work properly for your machine, remove it via:

sudo apt-get remove nvidia-340

sudo apt-get autoremove

sudo add-apt-repository -r ppa:graphics-drivers/ppa

Press Ctrl+Alt+F2 to get into console (or boot into recovery mode) if the new driver mess up the graphical session.

  1. How to use this driver with prime-identicator from webup8 PPA?

    • Not sure if the indicator works for this driver. If you want to give a try, first install this driver as well as the packages nvidia-prime, nvidia-settings, python-appindicator, then reboot and install the indicator if everything’s OK and finally log out and back in.

    • If you install prime indicator with the ppa, it will uninstall the 340 drivers and install the 331 driver. I haven’t tried any other method yet.

  2. i have prime nvidia with indicator work great with my intel hd 3000 and nvidia 540m i want to update my nvidia to Nvidia 340.46 is there a save way to make these without any trouble.
