NVIDIA announced the first stable release of the 555 series driver for Linux few days ago.

It’s NVIDIA 555.58, the latest new feature branch version. The release now uses GSP firmware by default on all GPUs that support it (e.g., Tesla T4, T10, A100 series).

GSP, stands for GPU System Processor, acts like a CPU embedded into the GPU, it can be used to offload GPU initialization and management tasks. To disable this feature, user can just add NVreg_EnableGpuFirmware=0 kernel parameter to /etc/default/grub config file if boot with Grub2.

NVIDIA announced the first stable release for 550 series Linux driver this Friday. It’s NVIDIA Driver 550.54.14 released as latest production branch version.

The release brings better support for Wayland, the more security touchscreen and HiDPI friendly display server, that’s already default in Ubuntu, Fedora, and other Linux with recent GNOME Desktop. They include:

  • NVIDIA VDPAU driver for hardware video acceleration can run in XWayland.
  • Support GNOME ‘Night Light’ and KDE ‘Night Color’ features on Wayland.
  • Support for PRIME render offload to Vulkan Wayland WSI.
  • Add support for virtual reality displays, such as the SteamVR platform, on Wayland compositors support DRM leasing.
  • Fix Source 2 engine games hang on Wayland session.
  • Fix that Wayland apps sometimes run at extreme low frame rate on Maxwell, Volta, and Pascal series GPUs.
  • Fix VRR (Variable Refresh Rate) not working with Wayland.

For Ubuntu machine with NVIDIA graphics card, here’s how to implement hardware acceleration for video playback in Firefox web browser.

Firefox so far only supports VA-API for GPU decoding to offload CPU and save power. Both Intel and AMD GPUs support VA-API. However, NVIDIA so far supports the api only through the open-source Nouveau driver.

If you have only NVIDIA GPU running with proprietary driver, then hardware video acceleration does not work out-of-the-box for Firefox.

For choice, there are libvdpau-va-gl1 driver (h.264 only) or libva-vdpau-driver, but both seems no longer updated. The best choice so far is the free open-source nvidia vaapi driver.

NVIDIA announced 545.29.02 graphics driver for Linux yesterday, as a new release series for its New Feature Branch Version.

For Ubuntu 22.04 + and Fedora Workstation with default GNOME on Wayland, as well as KDE on Wayland, the new driver adds support for the CTM, DEGAMMA_LUT, and GAMMA_LUT DRM-KMS CRTC properties, which, finally make the ‘Night Light’ and ‘Night Color’ feature work for NVIDIA users.

Night Light finally works on Wayland with NVIDIA driver

For desktop GPUs, the release adds initial experimental support for runtime D3 (RTD3) power saving mode. When all the PCI functions are idle, and all required conditions are satisfied, your GPU will go to the lowest power state resulting into maximum power savings.

The new driver also added experimental support for framebuffer consoles. On kernels with implement features, nvidia-drm will install a framebuffer console when loaded with both modeset=1 and fbdev=1 kernel parameters. Though, when an nvidia-drm framebuffer console is enabled, unloading nvidia-drm will cause the screen to turn off.

Other changes in NVIDIA 545.29.02 include:

  • Experimental HDMI 10 bits per component support
  • Support for virtual reality displays
  • CERTIFIED-quality support for GeForce and Workstation GPUs to open kernelmodules.
  • Support for PRIME render offload to Vulkan Wayland WSI
  • Support for HDR signaling
  • Add support to NVIDIA VDPAU driver for running in Xwayland
  • Support EGL_ANDROID_native_fence_sync EGL extension.

For more about the new driver, see the official release note.

How to Install NVIDIA 545 Driver

Ubuntu will build the new driver series and publish through official system repositories. So, just wait! It will be available in “Additional Drivers” utility when it’s ready.

For those who can’t wait, the “Graphics Drivers” team PPA has made the driver package for Ubuntu 20.04, Ubuntu 22.04, and higher.

Simply, press Ctrl+Alt+T on keyboard to open terminal. Then, run command to add the PPA:

How to Install NVIDIA 520 in Ubuntu

NOTE: Though it’s tested and works good in my case, it might still breaks your system (usually boot into blank screen) due to various reasons (e.g., upstream bug or corrupt installation)! So don’t do it in production machine!

The driver package is available now for Ubuntu 18.04, Ubuntu 20.04, and Ubuntu 22.04. For Ubuntu 22.10 user, it’s so far in pre-released repository, though should be published soon in next few days.

1. First, it’s HIGHLY recommended to update system by launching ‘Software Updater‘ and install all available updates! And, restart your system if it asks.

2. Second, search for and open ‘Additional Drivers‘ from Activities overview screen.

3. When it opens, choose “nvidia-driver-520” from the list, and click ‘Apply Changes’ button to install the driver.

In case you don’t see the 520 driver in the list, navigate to the first ‘Ubuntu Software’ tab, and make sure the 4 repositories (main, universe, restricted, multiverse) are enabled. Finally, close and Reload, and re-open the utility.

After installation, the ‘Additional Drivers‘ utility should prompt to restart your computer to apply change.


After restarting computer, open ‘Settings‘ and navigate to ‘About‘ page to verify if your NVIDIA graphics card is in use.

And, search for and open ‘NVIDIA Settings‘ utility to for driver version, GPU switching, and other settings.

Due to bug, you can’t switch to Intel (Power Saving Mode) with the tool, you can however install an extension to do the job via system status menu option.

Install ‘Prime indicator’ for switching GPU

For Ubuntu 22.04, search for and install ‘Extension Manager‘ from Ubuntu Software app. Then, use the tool to search and install ‘Prime Inidcator’.

For Ubuntu 20.04 and Ubuntu 18.04, first open terminal (Ctrl+Alt+T) and run command to install the agent package:

sudo apt install chrome-gnome-shell

Then visit the extension web page and use the ON/OFF switch to install it:

In case you don’t see the ON/OFF switch, follow the link in that page to install browser extension and refresh.

After installing the extension, go to top-right system status menu to switch between Intel, NVIDIA, and hybrid mode.

IMPORTANT: The Extension will automatically log out once your select another GPU mode and confirm with password!!! Save your works before doing change.

This simple tutorial shows how to install the NVIDIA proprietary driver in Ubuntu 22.04 and switch between dedicated and integrated GPU.

Since Ubuntu provides the proprietary driver packages via its restricted repositories, user may install NVIDIA driver as easy as a few clicks.

Install NVIDIA Driver

1.) Firstly, click on top-left corner ‘Activities‘, and then search for and open ‘Softwre & Updates’ utility.

When the tool opens, make sure the “Proprietary drives for devices (restricted)” is enabled.

Make sure ‘restricted’ repository enabled

2.) Next, navigate to ‘Additional Drivers‘ tab. There it should list all available graphics drivers.

If it shows nothing, press Ctrl+Alt+T to open terminal and run command sudo apt update to refresh package cache. Then re-launch the ‘Software & Updates’ utility.

Choose one of the drivers from the list and click on ‘Apply Changes‘ to install it. There will be a little bar indicates the installing process. When done, restart your computer!

Switch between NVIDIA and Intel Graphics:

After restart, your machine will be on performance mode with the dedicated GPU. To switch GPU mode, search for and open ‘NVIDIA X Server Settings‘.

When the app opens, navigate to ‘PRIME Profiles‘. Then you’ll see three options available in the right:

  • NVIDIA (Performance Mode) – use dedicated NVIDIA GPU to render Ubuntu desktop.
  • NVIDIA On-Demand – use integrated graphics to render desktop, but possible to offload specific apps via dedicated GPU.
  • Intel (Power Saving Mode) – use integrated graphics to render Ubuntu desktop.

In my case, the “Intel (Power Saving Mode)” is somehow grayed out. As a workaround, choose Intel graphics card by running sudo prime-select intel in terminal.

Changing GPU mode however needs log out and back in to apply changes.

Run certain apps via NVIDIA GPU while rendering desktop via integrated graphics

By setting GPU mode to “NVIDIA On-Demand”, you may run certain apps via NVIDIA GPU, while others handled by the integrated GPU.

1.) For CUDA apps, you need to run command in terminal (Ctrl+Alt+T) to install the nvidia-cuda-toolkit package.

sudo apt install nvidia-cuda-toolkit

Then there’ll be application-specific menu to tell it which device to use.

2.) For other apps, just use the following environment variables.


You can do this by launching apps from command line. For example, launch SuperTuxkart (a kart racing game) via command:


Or, edit the application’s .desktop file which is usually under “/user/share/applications” directory. And, change the line of ‘Exec’ to:

Exec=env __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia supertuxkart

Add System Menu option to Switch CPU

To make it easy to switch between your GPUs, there’s a Gnome Extension available to add options into system tray menu.

1.) To get the menu option, you need to first install the open-source EnvyControl tool. Press Ctrl+Alt+T on keyboard to open terminal, and run the command below one by one:

  • Use git command to grab the source:
    git clone
  • Navigate to the source folder, and install it for global use via pip package manager:
    cd envycontrol && sudo pip3 install .

If the pip3 command does not exist, run sudo apt install python3-pip command to install it.

As the project page mentioned, users have to run the following 2 commands one by one to prevent Ubuntu’s own gpu-manager from interfering:

sudo prime-select on-demand
sudo systemctl disable gpu-manager.service

2.) Next, run command to make sure you have the agent packages installed for installing Gnome Extensions:

sudo apt install chrome-gnome-shell gnome-shell-extension-prefs

3.) Finally, go to the extension page and turn on the slider icon to install it:

NOTE 1: The pre-installed Firefox does not support this stuff so far! Use another browser, or install back Firefox as classic deb package.

NOTE 2: If you don’t see the on/off switch in that page, click the ‘click here to install browser extension‘ to install extension for your web browser and refresh the page.

The menu option should appear immediately after successfully installed the extension. If not, press Windows (Super) key on keyboard or click “Activities” on top panel, and then search for and open the “Gnome Extensions” app to manage your extension.

1. To add the PPA, open terminal (Ctrl+Alt+T) and run command:

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

Type user password for sudo prompt (no asterisk feedback) and hit Enter to continue.

2. Then launch Additional Drivers utility, choose Nvidia 450 and apply changes.

Sorry I can’t see these drivers as I don’t have a discrete graphics card in my laptop :(

(Optional) To remove the PPA repository, either go to Software & Updates > Other Software, or run command:

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

Nvidia Linux driver

For Ubuntu 18.04 users plagued by screen tearing issue while using NVIDIA proprietary drivers, this quick tutorial may help you via enable PRIME Synchronization on Optimus.

Screen tearing usually happens on Ubuntu Linux laptop that uses Prime to switch between NVIDIA and Intel drivers.

1. Open terminal (either via Ctrl+Alt+T or by searching for ‘terminal’ from software launcher) and run command to create a new config file:

sudo gedit /etc/modprobe.d/nvidia-drm-nomodeset.conf

Type your password (no asterisks feedback) when it prompts and hit Enter.

2. When the file opens after running the previous command, add following line and save the file.

options nvidia-drm modeset=1

3. Finally update intramfs and reboot your machine.

sudo update-initramfs -u

To check if previous changes work after reboot, run command:

sudo cat /sys/module/nvidia_drm/parameters/modeset

It should output ‘Y’.

In addition, to get much SMOOTHER Nvidia window dragging experience, you can also do:

1. Set maximum performance in Nvidia X Server Settings -> PowerMizer.

2. If you have MORE than enough RAM, set swap tendency to a MUCH lower value by running command to edit sysctl.conf:

sudo gedit /etc/sysctl.conf

and add following 2 lines when the file opens:
