    They work fine on wayland when they are not being used as a primary GPU. My optimus laptop (680M + RTX3050) works perfect on Wayland because 99% to 100% of the time it actually uses the AMD GPU for the desktop things. It only uses the discrete Nvidia GPU when I tell it to for games and the like. My desktop that is nvidia-only though is another story, last time I tried I got significant cursor glitches after waking from sleep, the night light doesn’t work due to the lack of GAMMA_LUT like you mentionned. There were also all sorts of glitches with Blur my shell iirc

      I have the laptop set to NVidia Dedicated mode, the integrated GPU is dormant at all times (verified with nvtop), so I don’t have any experiences with Optimus. I don’t use suspend, I turn it on in the morning, off in the evening.
