I had to do a fresh of 24.04 and now when I look in the additional drivers section I do not see the drivers for my GPU when they were there on previous version.
I tried to follow this guide, but it doesn't work. When I run the first command to get the driver version installed I get no return. When I run the next commands to tell it to install a driver it tells me I already have all available drivers installed.
I looked up on the nvidia website for my GPU and I am pretty sure I need to install latest 390 version because it's the one that lists my card as supported. So I tried running sudo ubuntu-drivers install nvidia:390.157
and got the return that all available drivers are installed but still get nothing when running the command to check which drivers I have. cat /proc/driver/nvidia/version
So I tried downloading the drivers directly from NVIDIA and just installing them, but when I do this it says I can't install drivers while X server is running, which I am not entirely sure what that is. My loose understanding of it is that it's what produces the UI that I interact with so if I shut it down I don't know if I can install the drivers, so at this point I am assuming I have missed something obvious somewhere and I am hoping someone will help me realize the very simple answer I somehow missed.
