While this may work (I did not try tbh), it is not an ideal solution. The greeter should reflect changes done via gsettings/dconf-editor.
Also, as I checked today, this is not specific to Ubuntu MATE. Same issue exists in LinuxMint when arctica-greeter is installed and enabled. I raised an issue on github. Ref: https://github.com/ArcticaProject/arctica-greeter/issues/17
