I got similar experience. I really prefer switch CUDA version with whole PC machine. What is more, the speed and memory of hardware improves quickly in time as well.

I update drivers regularly. I've only had one display failure and was solved by a simple rollback. To be a bit fair (:/) it was specifically a combination of new beta driver and a newer kernel. It's definitely improved a ton since 10 years ago I just would not update them except very carefully.

I've bricked multiple systems just running apt install on the Nvidia drivers. I have no idea how, but I run the installation, everything works fine, and then when I reboot I can't even boot.

That was years ago, but it happened multiple times and I've been very cautious ever since.

Interesting. I've never had that issue (~15 years experience) but I always had CPUs with graphics drivers. Do you think that might be it? The danger zone was always at `startx` and never before. (I still buy CPUs with graphics drivers because I think it is always good to have a fallback and hey, sometimes I want to sacrifice graphics for GPU compute :)

I have been having a fine time with a 3080 on recent Arch, FWIW.

HDR support is still painful, but that seems to be a Linux problem, not specific to Nvidia.
