NVIDIA driver 352.21 for Linux has been released recently with new GPUs support and numerous bug fixes. Here’s how to install it in Ubuntu 15.04, Ubuntu 14.04 and their derivatives via PPA.

Nvidia 352.21 release highlights:

• Added support for the following GPUs:
  • GeForce 720A
  • GeForce 920A
  • GeForce 930A
  • GeForce 940A
  • GeForce GTX 950A
  • GeForce GTX 980 Ti
• Fixed a bug that caused the Display Configuration page of the nvidia-settings control panel to automatically generate layouts with multiple displays occupying the same position when enabling or disabling Base Mosaic.
• Updated nvidia-settings to allow the use of the standard Display Configuration page when SLI Mosaic is enabled.
• Fixed a bug that caused the kernel to report errors when unmapping DMA allocations on kernels with CONFIG_DEBUG_DMA_API enabled.
• Added GLX Protocol support for the following OpenGL extensions:
  • GL_ARB_copy_buffer
  • GL_ARB_texture_buffer_object
• Fixed a bug that caused a kernel crash if SLI Mosaic and G-SYNC were used at the same time on a configuration with more display devices connected to one GPU than another.
• Added the ability to configure the swapping behavior for quad-buffered stereo visuals. The driver can be configured to independently swap each eye as it becomes ready, to wait for both eyes to complete rendering before swapping, or to allow applications to specify which of these two behaviors is preferred by setting the swap interval. This setting can be adjusted in the nvidia-settings control panel, or via the NV-CONTROL API.
• Fixed a regression which caused the GPU fan status display to disappear from the nvidia-settings control panel.
• Added reporting of ECC error counts to the nvidia-settings control panel.
• Fixed a bug that sometimes prevented OpenGL sampler objects from being properly deallocated when destroying OpenGL contexts.
• Fixed a bug that caused GLX_EXT_framebuffer_sRGB to incorrectly report sRGB support in 30 bit-per-pixel framebuffer configurations.
• Added support for G-SYNC with sync-to-vblank disabled. This allows applications to use G-SYNC to eliminate tearing for frame rates below the monitor’s maximum refresh rate but allow tearing above the maximum refresh rate in order to minimize latency.
• When G-SYNC is active and sync-to-vblank is enabled, the frame rate is limited to the monitor’s maximum refresh rate.
• GLSL gl_Fog.scale is now +infinity when gl_Fog.end equals gl_Fog.start. Previously, the value 0 was used, but this broke certain applications such as the game XIII running on Wine (Wine bug #37068).
• Enabled G-SYNC by default when Unified Back Buffer (UBB) is disabled.
• Updated the NVIDIA GPU driver to avoid using video memory already in use by vesafb.
• Fixed a bug in nvidia-settings that caused the application to crash when saving the EDID to a file.
• Fixed a bug that prevented the “mkprecompiled” utility included in the driver package from reading files correctly.
• Fixed a bug that could cause an Xid error when terminating a video playback application using the overlay presentation queue in VDPAU.
• Updated nvidia-installer to avoid recursing too deeply into kernel source trees under /usr/lib/modules, mirroring an existing restriction on recursion under /lib/modules.
• Fixed a rare deadlock condition when running applications that use OpenGL in multiple threads on a Quadro GPU.
• Fixed a kernel memory leak that occurred when looping hardware- accelerated video decoding with VDPAU on Maxwell-based GPUs.
• Fixed a bug that caused the X server to crash if a RandR 1.4 output provided by a Sink Output provider was selected as the primary output on X.Org xserver 1.17 and higher.
• Fixed a bug that caused waiting on X Sync Fence objects in OpenGL to hang indefinitely in some cases.
• Fixed a bug that prevented OpenGL from properly recovering from hardware errors or sync object waits that had timed out.

Install NVIDIA 352.21 via PPA:

NOTE: If you’re just looking for a working driver for your graphics card, the default Nvidia package in Ubuntu repository may interact better with the rest of your distribution’s framework.

Open terminal from the Dash, Application Menu, or by pressing Ctrl+Alt+T on keyboard. When it opens, run below commands one by one to add the PPA, and install the driver:

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

sudo apt-get update

sudo apt-get install nvidia-352 nvidia-settings

A new Linux graphics driver NVDIA 346.59 was released with all GeForce 900 series notebook GPUs support, e.g., GeForce 920M, 930A, 930M, 940M, GTX 950M, GTX 960M. Also GTX TITAN X, Quadro K1200, M6000 GPUs are added support in this release.

Besides that, following bugs has been fixed in NIVDIA 346.59:

• Fixed a bug that caused corruption when switching display modes in some applications that use transform feedback.
• Fixed a bug that caused texture corruption on framebuffer depth attachments cleared using glClearTexImage().
• Fixed a bug that artificially limited the maximum pixel clock on displays in some SLI Mosaic configurations.
• Fixed a kernel memory leak that occurred when looping hardware- accelerated video decoding with VDPAU on Maxell-based GPUs.
• Fixed a bug that could cause nvidia-settings to crash on exit on 32-bit Linux systems.

Install NVIDIA 346.59 from PPA:

The new release has been made into PPA repository, available for Ubuntu 14.10 and Ubuntu 15.04.

To install it, open terminal (Ctrl+Alt+T) and run below commands one by one:

sudo add-apt-repository ppa:mamarley/nvidia

sudo apt-get update

sudo apt-get install nvidia-346

For Ubuntu 14.04 and other Linux, you may download the official binary from nvidia page, and follow this how-to-install guide.

Nvidia has recently released a new driver version 346.47 for Linux with new GPUs support and a few bug fixes.

According to the release highlight, Quadro K620M, Quadro K2200M, and GeForce GTX 965M GPUs are added supported in this driver release.

And below bugs are fixed:

• Fixed a bug that could cause rendering corruption in GLX clients using PBOs and/or VBOs when using GLX indirect rendering.
• Fixed a bug that caused Xinerama layouts which included X screens with ‘Option “UseDisplayDevice” “none”‘ to be represented incorrectly in the nvidia-settings control panel.
• Fixed a bug that could cause glXSwapBuffer() to block for longer than necessary in multi-threaded GLX applications using the GLX_NV_delay_before_swap extension.
• Fixed a bug that caused OpenGL applications using the NV_path_rendering extension to crash after a modeswitch event.
• Fixed a bug that caused DisplayPort audio to stop working after monitors are hotplugged.

If you want to install or upgrade this Nvidia driver, download it from THIS PAGE and follow this guide to install it on your Ubuntu.

Or wait it to be built into Xorg Edge PPA.
