Problems setting scaling factor in Gnome (HiDPI, xorg)

I'm struggling to set my desktop scaling from the command line via the instructions on https://wiki.archlinux.org/index.php/HiDPI#GNOME

The command

 gsettings set org.gnome.desktop.interface scaling-factor 2 

changes the scaling factor predictably, and this change is visible in dconf-editor, but it makes no difference in the display.

My understanding is that this setting should correspond to the Settings->Devices->Displays->Scale option in gnome-control-center, which does not change when I run the command in gsettings, or when I change the value in dconf-editor.

On login, I run

 xrandr --output DP-4 --scale 1.5x1.5 

which adjusts the scaling as expected, and for some reason resets Settings->Devices->Displays->Scale to 100% while leaving the value of org.gnome.desktop.interface scaling-factor unchanged. My real question is how I could set this back to 200% from the terminal so that I can include this in a script on login.

I'm not sure if this is related, but I get this output when running gnome-control-center from the terminal (and the GUI launches and behaves correctly)

 $ gnome-control-center
(gnome-control-center:5079): Clutter-CRITICAL **: 14:08:49.554: Unable to initialize Clutter: Unable to initialize the Clutter backend: no available drivers found.
Segmentation fault (core dumped)

Thank you.
