I've been a Linux user for almost 30 years but never had to tinker with any software to solve a problem. Cue a Fedora upgrade to somewhere around 38. I've been using the multiseat feature for years. It's alway seemed very fragile. With this upgrade it was seriously broken. I managed to find a patch someone made that for some reason wasn't accepted into the gnome-shell package. I was able to grab the patch, rebuild the RPM package and install the update to my system and restore multiseat. It was actually pretty effortless. The hardest part by far was finding the fix. Now updating to Fedora 41 I had to do the same process again. Apparently the problem still exists. This time I had to create a new patch as the original one wouldn't apply anymore but that wasn't very hard. It was very satisfying to be able to fix that problem and it was only possible due to the OSS community.
