I'm getting this error from nitrogen --restore on EndeavourOS and BSPWM (version 0.9.12 of bspwm):

I only have a single display.

The version of nitrogen I have installed is aur/nitrogen 1.6.1-6 (incidentally, nitrogen is currently orphaned in the AUR).

This looks like it might be along the same lines as #152 (was that fix finished?)
