… but I’m not running Xfce. I should prolly try in a VM.

I’d lean towards including xfce4-screensaver, since that’s the intended
use of Xfce, but only once it actually works.

Applied after changing ‘which’ to refer to the “xset” input so that it
works correctly when cross-compiling.
Closing, and let’s discuss xfce4-screensaver separately!
