I understand from here and other places that Wayland offeres per-monitor scaling settings to handle cases such as a HiDPI laptop screen with a low DPI external monitor (my situation). I installed Wayland from the
gnome-session-wayland package and can run Wayland just fine, but the scaling issue remains.
How do I set the per-monitor scaling when running Wayland?
Confirmation that I'm actually running Wayland:
~>loginctl show-session 1 -p Type Type=wayland ~>gnome-shell --version GNOME Shell 3.18.5
