> Why do we say that Nvidia does not have enough driver support on linux?
It's a long story.
Nvidia has provided pretty-good datacenter/CUDA support on Linux for a long time, now. The problem is desktop Linux. Nvidia wanted to focus on supporting the old x11 desktop server at a time when most distros were switching to Wayland as a replacement. Nvidia tried to fix the issue by giving Linux devs a proprietary render API to develop Wayland support on, but it was largely rejected since it required writing a lot of platform-specific code. For a few years, the only way to properly accelerate Wayland on Nvidia hardware was to use the reverse-engineered Nouveau drivers that broke most desktop software - a catch-22 for Nvidia users that wanted a more updated desktop experience.
Very recently, a few things started changing. For one, Nvidia started to shuffle around their proprietary GPU code to make their hardware more open and modular. For two, starting with 510-series drivers and continuing through 535 and 555, Nvidia has started to make Wayland support a priority. In the long-term this should resolve the issue of Nvidia GPUs requiring special workarounds to support modern desktops.
They are pretty distinct. Having good CUDA drivers didn't mean raster graphics were accelerated well, and for a while the bulk of Nvidia's efforts were focused on a depreciated backend.
The good news is that those days are mostly behind us, with the more recent Nvidia drivers. Guess the crypto/AI boom helped them find the cash to hire better Linux devs.
