Ubuntu – Gsettings error: using the memory backed


My laptop has very high resolution and I often want to change the scale factor. Until recently the following command worked just fine

gsettings set com.ubuntu.user-interface scale-factor "{'eDP1': 16 }"

But now I am getting the error

GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings will not be saved or shared with other applications.

I tried all the proposed solutions including the accepted answer in this post but none worked. If I open the dconf-editor GUI I can change the scale factor just fine but this is less convenient. I'm lost as to how to fix this but I would love to be able to change the scale factor via a command instead of a GUI.

Try running the following command line first:

export GIO_EXTRA_MODULES=/usr/lib/x86_64-linux-gnu/gio/modules/
