+Note: the `scaling-factor` and `text-scaling-factor` might already have been set in an AppVM's user profile, in which case they'll override the system-wide ones. To use the system-wide values, reset the user values like so in the AppVM(s):
+
+~~~
+gsettings reset org.gnome.desktop.interface scaling-factor
+gsettings reset org.gnome.desktop.interface text-scaling-factor
+~~~
