If you’re not using Windows with an Nvidia GPU, be prepared to put in some frustrating extra work. I know, since I’m running mine on Fedora Linux with a 7900XT. And it took me three attempts and several hours of googling, just to get it running properly.

But basically, you’ll want to start out by using the Automatic1111 WebUI. Yes, it’s called WebUI, but it runs completely locally.

Just make sure you’re using the exact python version required (3.10.6). Make sure that all the dependencies are properly installed. Make sure your drivers are up to date. Make sure that you’re running the webui.sh from the same folder that also contains the webui-user.sh. And you’ll probably still run into issues.

The WebUI is probably not the best thing for Linux folks out there (though it’s gotten a lot better compared to one year ago), but it’s probably the most popular way for us common folks to interact with stable diffusion. So there’s a ton of material on how to use it out there, and that includes Linux folks asking questions with answers which aren’t just “use windows”. So if you inevitably run into trouble, you’ll get at least some hints on how to fix it.

Good luck
