I found from Nvidias site that version 550 of driver was the latest and stable driver they offer.
I installed it last night and tested my games and general apps and it seems to work fine.
With the added bonus that my GPU seems to run much cooler now.
Maybe I should make an Gnome app that shows updates for the driver, in my summer vacation.
NVIDIA offers an apt repository for many distributions, including Ubuntu. You can find instructions for setting it up here.
I run Debian, and the driver version in their repos is something archaic like 525, so I was in a similar situation. But the NVIDIA apt repository has the latest 555 driver along with all their CUDA tools, NVAPI and OptiX libraries for games, etc.
I prefer the apt repository to a runfile because I get served updates automatically with an apt upgrade, like with any other software on my system.
Now I am just wondering how to keep my drivers updated, with the latest stable release.
Without manually checking Nvidias website. I hope I can find some API or feed that can tell me that out here on the internet.
