How to Install NVIDIA 346.35 in Ubuntu:

Before the xorg-edgers PPA updates for this driver, you can download & install the official NVIDIA package by following below steps:

1. Select download the official installer from links below:

32-bit Linux | 64-bit Linux | 32-bit ARM Linux

32-bit or 64-bit? Check your OS type by going to top-right corner shutdown menu (gear button) and clicking ‘About This Computer’

2. To be able to install the new driver, you have to remove the previous driver by running below command in a terminal window (Open terminal from the Dash or by pressing Ctrl+Alt+T on keyboard):

sudo apt-get remove nvidia* && sudo apt-get autoremove

3. You should also blacklist the open source nouveau driver by running below command to edit the config file:

gksudo gedit /etc/modprobe.d/blacklist-nouveau.conf

Add below lines to the end and click save.

blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off

4. You can also disable the Kernel Nouveau by running below commands one by one:

echo options nouveau modeset=0 | sudo tee -a /etc/modprobe.d/nouveau-kms.conf

sudo update-initramfs -u

5. Finally reboot your computer and when you’re at the login prompt press Ctrl+Alt+F1 (or F2 ~ F6) to switch to command console. Login with your username and password.

6. When you’re at the black & white text console, the graphics session is still there and you can switch back by pressing Ctrl+Alt+F7. You have to kill the graphics session by running below command:

sudo stop lightdm

Replace lightdm with gdm, mdm, or kdm for GNOME, Linux Mint, or KUbuntu.

7. At last give permission to the downloaded package and run it:

cd ~/Downloads && chmod +x NVIDIA-Linux-*-346.35.run && sudo sh NVIDIA-Linux-*-346.35.run

Follow the on screen prompts and when everything’s done reboot your computer. In next boot after log in, run sudo nvidia-xconfig to save your new nvidia configuration.

(Optional) To remove the driver, re-do step 5 & 6 and run:

cd ~/Downloads && sudo sh NVIDIA-Linux-*-346.35.run --uninstall

Also undo the step 3 & 4 by removing the

cd /etc/modprobe.d/ && sudo rm blacklist-nouveau.conf nouveau-kms.conf && sudo update-initramfs -u

Good luck!

NVIDIA has announced the 340.65 release of its Linux graphics driver (long lived branch version) with latest Kernel (3.18) support and various bug fixes.

Here’s the release highlight for NVIDIA 340.65:

• Added support for X.Org xserver ABI 19 (xorg-server 1.17).
• Improved compatibility with recent Linux kernels.
• Fixed a bug that prevented internal 4K panels on some laptops from being driven at a sufficient bandwidth to support their native resolutions.
• Fixed a regression that prevented the NVIDIA kernel module from loading in some virtualized environments such as Amazon Web Services.
• Fixed a regression that caused displays to be detected incorrectly on some notebook systems.
• Fixed a bug that could cause X to freeze when using Base Mosaic.
• Fixed a regression that prevented the NVIDIA X driver from recognizing Base Mosaic layouts generated by the nvidia-settings control panel.

Install / Upgrade NVIDIA Driver in Ubuntu:

If you’re running with NVIDIA’s proprietary driver in Ubuntu, you can upgrade to this driver release by following below steps:

1. Press Ctrl+Alt+T to open terminal. When it opens, run the command below to add the xorg-edgers fresh X crack PPA repository:

sudo add-apt-repository -y ppa:xorg-edgers/ppa

Type in your user password when it asks.

2. After added the PPA, refresh your system cache via command:

sudo apt-get update

3. Finally install the 340.65 driver:

sudo apt-get install nvidia-340

The repository also provides the NVIDIA 343 driver (short lived branch version) and NVIDIA 346 driver (still in beta). If need, you can replace nvidia-340 in the previous code with nvidia-343 or nvidia-346 to install the driver.

While Nvidia’s Linux Graphics Driver 346 series is still in beta, the latest 343.36 stable driver has been released this Friday, which brings support for the latest Linux kernels (up through Linux 3.18), various bug fixes (including an Unreal Engine 4 fix), support for disabling indirect GLX, and more.

Release Highlight in Nvidia Graphics Driver 343.36:

• Added support for X.Org xserver ABI 19 (xorg-server 1.17).
• Improved compatibility with recent Linux kernels.
• Fixed a bug that rendered very bright garbage data onto some textures in UnrealEngine 4 applications. This issue is known as the “disco bug” by the UnrealEngine 4 Linux community.
• Added option UseSysmemPixmapAccel to control the use of GPU acceleration for X drawing operations on pixmaps allocated in system memory.
• Fixed a regression that prevented the NVIDIA X driver from recognizing Base Mosaic layouts generated by the nvidia-settings control panel.
• 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.
• Fixed a crash with UnrealEngine 4 when the application was started with the -opengl4 commandline switch.
• 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.
• Fixed a bug that could prevent 32-bit GPU-based applications from running correctly on 64-bit systems when using GPUs with very large memory-mapped I/O regions.
• Fixed a bug that could cause the CUDA debugger to fail after exiting X on systems with persistence mode enabled.
• Fixed a bug that could cause silent and intermittent failures when a CUDA application writes to a peer device’s memory with GPUDirect.
• Updated nvidia-installer to avoid writing to non-zero offsets of sysctl files in /proc/sys/kernel.
