It makes wl-clipboard work properly in neovim, without having to create
a transparent surface that steals focus and causes flickering. It's also
required for clipman.
The code in this else completely freezes my system when I run the
swayidle command to replicate xset dpms force off. No idea if it works
on multiple monitors, but for now avoid running when there's 1 monitor.
Also remove the comment with the function name in sway.
