The change made the Linux kernel-module portion of the driver available under dual GPL/MIT licensing; it did not open-source NVIDIA’s entire driver stack. NVIDIA’s current guidance supports the open module flavor on Turing and newer GPUs and has made it the default, suggested option since the 560 driver series.
What NVIDIA open-sourced—and what stayed closed
The announcement covered NVIDIA’s Linux GPU kernel modules, the code that interfaces with the Linux kernel. NVIDIA released that code under dual GPL/MIT terms beginning with R515. Its user-mode components—including CUDA—remained closed-source and distributed as prebuilt binaries. The open kernel modules work with NVIDIA firmware and user-mode software such as CUDA, OpenGL, and Vulkan, but the components need to come from a matching driver release.
So “NVIDIA open-sourced its GPU driver” is an overstatement unless it is immediately qualified: NVIDIA published the Linux kernel-module portion, not the complete driver software stack. The official source repository describes the project as Linux open GPU kernel modules.
Does your NVIDIA GPU support the open modules?
NVIDIA’s current driver installation guide limits the open module flavor to Turing and newer architectures. Maxwell, Pascal, and Volta GPUs require the proprietary module flavor. The open flavor has been NVIDIA’s default and suggested installation starting with the 560 driver release series.
#1 Best Overall
- AI Performance: 767 AI TOPS
- OC mode: 2632 MHz (OC mode)/ 2602 MHz (Default mode)
- Powered by the NVIDIA Blackwell architecture and DLSS 4
- Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure
- A 2.5-slot design maximizes compatibility and cooling efficiency for superior performance in small chassis
Check the exact GPU model and the instructions for your Linux distribution and driver branch before installing. The source repository’s compatibility information can help confirm which models are supported. You do not need to buy new hardware just because NVIDIA published the modules: an existing compatible GPU is the relevant requirement.
Open and proprietary module flavors compared
| Question | Open module flavor | Proprietary module flavor |
|---|---|---|
| Which GPU generations? | Turing and newer, subject to exact model compatibility in NVIDIA’s guide and repository. | Required for Maxwell, Pascal, and Volta. |
| Is the whole driver open-source? | No. The Linux kernel modules are open-source; user-mode components remain closed-source. | No. This flavor does not make the user-mode stack open-source either. |
| Which should most eligible users choose? | NVIDIA’s default and suggested option since the 560 driver release series. | Needed for the older GPU architectures identified above. |
How to install without mixing incompatible components
NVIDIA provides distribution-specific package instructions in its current installation guide. The source repository also describes building and installing the modules directly, but that route requires attention to release matching: the kernel modules need corresponding GSP firmware and user-space driver components from the same driver release. Do not combine a module build from one release with user-space components from another.

- Powered by GeForce RTX 5070 Ti
- Integrated with 16GB GDDR7 256bit memory interface

- Confirm your GPU model and architecture against NVIDIA’s current compatibility information.
- Open NVIDIA’s installation guide for your Linux distribution and select instructions that match your intended driver branch.
- Use the open flavor if your GPU is supported and you are following NVIDIA’s current recommendation; use the proprietary flavor where the guide requires it.
- If building from source, follow the repository instructions and keep the kernel modules, firmware, and user-space components on the same driver release.
Driver branches, supported-device lists, and distribution package instructions can change, so use the current NVIDIA documentation rather than copying commands from the 2022 announcement.

At launch in 2022, NVIDIA described support for data-center GPUs in the Turing and Ampere families as production-ready, while GeForce and Workstation support was alpha-quality. Those labels describe the state NVIDIA reported at the time; they are not a current quality rating. For a present-day installation, rely on the current guide’s recommendation and the exact GPU and driver-release compatibility information.
