Recently, I used to use Ubuntu 22.04.02 and Cuda 11.7 and Stable diffusion 1.2.1.

One day, I updated all, and I found that Cuda wouldn't start.
The kernel was updated to 6.
At the same time my SSD was broken.
So I bought new one, and start to find more stable GUI.
Pricisely speaking, I asked Bing about that.
Bing told me that Pop!_OS exists.
It's for gaming and NVIDIA preinstalled.
The base is ubuntu.

This should work for stable diffusion.

I installed Pop!_OS.
it goes.

Download Pop!_OS from System76.
https://pop.system76.com/

Burn pop_os_22.04_amd64_nvidia_33.com in DVD. not USB.
At first place, I used my USB to install Pop_os.
But it didn't work. The installer was trying to refer cdrom/casper/filesystem.manifest-remove which did not exist.
And my usb's one Sector crrupted.

Then install pop!_os.
Ordinary way. Please refer System76 instruction site.

Install Cuda.
sudo apt install nvidia_cuda_toolkit
