@taylan I'm using i3, it's one of the default options in the installer, and added some packages. In my main PC I use openSUSE with KDE and although is the best KDE experience I've had, I wanted to try something new and GUIX is great.

BTW, at least so far all my hadware works without proprietary firmare so YMMV and you would probably need to install and configure the nonguix channel.
