I use EndeavourOS. Both are in the AUR, so it was really simple. (obligatory mention of the greatness of Arch Wiki)

The hardest part was figuring out how to get Waybar to disappear. It was showing below the Noctalia menubar.

Brodie Robertson just made a video about Niri.

So I tried out Noctalia shell.

I just love it. Beautiful, responsive, enough settings in the GUI. I think it’s a keeper.

I went Windows > Xfce > Plasma > Gnome
