Scale UI via command line

[Donnut]

Hi. I have Ubuntu 17.10 installed via Parallels, with a High DPI screen. However, I can't seem to set the UI scaling, it is not in the display settings. Is there a way to do this manually?

You can use gsettings in terminal.
eg

gsettings set org.gnome.desktop.interface scaling-factor 2
You may need to restart gnome-shell or logout to see changes.

To set back to default...

gsettings reset org.gnome.desktop.interface scaling-factor

Worked like a charm, thank you!
