Configure Nvidia's Digital Vibrance on Wayland
🔥 Description¶
NVIDIA GPUs have a nice feature called Digital Vibrance that increases the colors saturation of the display. The option is readily available on nvidia-settings, but is too coupled with libxnvctrl, making it softly "exclusive" to the X11 display server over wayland; but I paid for my pixels to glow :^)
An interesting observation is that the setting persists after modifying it on X11 and then switching to Wayland. I theorized (1) (2) it was possible to call some shared library or interface to configure it directly in their driver, independently of the display server, and indeed, it is possible!
This project uses nvidia-modeset and nvkms headers found at nvidia/open-gpu-kernel-modules to make ioctl calls in the /dev/nvidia-modeset device for configuring display attributes.
Note: A future intended way will be through NVML, as evident by some nvidia-settings comments
❤️ Consider supporting my work, this took 30 hours to figure out, implement, write a website, make it convenient 🫠
