What software have you found particularly frustrating or difficult to configure on Linux?
Probably vim. It works fine out of the box but it took me way too long to figure out things like why my terminal colors were never quite right out of the box (had to set it to 256 color mode or what have you). And once I wanted to use some a few plugins the configuration started getting a bit convoluted/confusing. Hoping I have time some day/remember to figure out how to disable that annoying visual paste mode or whatever it is called that sometimes makes using it over SSH a nightmare.
Jellyseer in docker. It won’t accept my jellyfin login. It just spins and spins. But I plan to use it locally. And everyone says you have to sign in initially not local? I don’t know. I’m annoyed with it and gave up for now.
Arch based distro (yes, even Manjaro).
Fortunately I haven’t had to open it in a very long time.
Nvidia drivers on Arch, KDE Plasma 6.
