what does this consist of? Well, it’s easy, whenever you install a new distribution of Linux, don’t customise anything, nothing please!! Out of the box experience, you may install software but that’s all. And if you are already using a customised distro, then delete the .config file and reboot, but please be careful and check your distribution wiki before doing that o.o
Debian, I use one Gnome extension but could easily do without it. All the defaults are fine if you just want to sit down and browse, edit media, create documents or write code.
