I am writing this to you from my NixOS desktop.

After I gave up on the idea of preserving an existing Linux install (that used a file system, namely, btrfs, that NixOS's installer does not currently handle), and just allowed NixOS's installer to nuke my block device (i.e., my "hard drive"), it was easy for me to set up and configure my NixOS install to my liking -- and I know very little about Nix and NixOS although I consider it worth learning, which probably greatly affected my attitude, which has historically had a large effect on whether I succeed or fail at sys-admin-y tasks.

Where the learning curve gets very steep is when I tried to build something from source code! I would've liked to have built Emacs 24.4 from source, because that is the version against which my Emacs Lisp code is tested, but I gave up. (I'm using Emacs 26 instead and spending time adapting my Lisp code -- something I probably never would've needed to do if I could've built 24.4 because I am moving off of Emacs.)

If you're using x86_64, there are tens of thousands of packages with pre-built binary packages, so it might be you never have to build something from source to get the desktop environment you want.
