Add screensavers or take X11 out of my cold, dead hands. I don't use a CRT but still like screensaver since it prevents me from having to wait 5 years for my screen to turn on.
Simple stuff like managing some dependency issues (like when packages get renamed), actually knowing how to use the command line (you don't need to learn awk, grep, and sed just yet), and knowing how your bootloader wants to be treated.
You'll get it as time passes, but Garuda assists in most of these things.
It's great! You can expect updates that don't take literal years, but you will need to maintain your system a bit more (Garuda provides utilities to make it easier).
Or Tiny11, which you can build.
