[SOLVED] GDM is not applying scaling when logged out

I've copied monitors.xml generated on Wayland session into ~gdm/.config/ and changed ownership to gdm:gdm. This should apply the GNOME display settings to GDM, according to ArchWiki. When logged in it works just fine but after boot or logout, no scaling is applied to GDM.

Any ideas on how to fix it?

Edit:

Ok, GDM was actually parsing the monitors.xml file I've copied. The reason it didn't scale before is that I'm using fractional scaling (1.5) and this feature needs to be enabled on gdm user for it to accept non-integer scale values. So I did:

# machinectl shell gdm@ /bin/bash

Then:

$ gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"

And now it's working fine.
