(A GPU driver is not ''purely'' kernel-mode; there are also userspace parts that allow the graphics API to use the kernel part. Mesa, for example, has serspace parts for Nouveau and NVK; they are automatically used when appropriate, so no configuration is needed.<ref>If you insist on checking which driver is in use, try running <code>vulkaninfo | grep -i "deviceName\|driverID"</code>. If you see DRIVER_ID_MESA_NVK, that means you are on the shiny new open-source Vulkan driver.</ref> Nvidia's two kernel drivers also need to be hooked up to X11 using userspace libraries.) | |||

The Nvidia open driver is ''very'' similar to its proprietary sibling. Most content in the proprietary section above apply; just copy over the proprietary config above and toggle the "open" option, and you are set. | |||
Like its proprietary sibling, it also requires some non-free userspace packages that allow X11 to talk to the kernel driver. As a result, you still need to enable unfree packages. | |||
Be warned that the Nvidia open driver is considered "beta quality". Performance may be very slightly lower. | |||
