And now, hilariously enough, they have ended up with a lot of their growth coming from Linux-based systems.

To be fair, I recently bought a new Thinkpad, and with Ubuntu 20.04 and Nvidia CUDA just worked, with absolutely no tuning (I didn't even need to set LD_LIBRARY_PATH, which I found pretty odd). So things seem to be improving, because there's money in it for Nvidia.

The Nouveau drivers have a throttled clock speed due to firmware signatures. And the proprietary drivers are complete mess on wayland, where most compositors and other GPU drivers use GBM, but Nvidia did their own thing and used EGLStreams. Maybe someday in the future the situation will improve, but historically, it hasn't been good.
