I need to install specific screen resolution 1600x900, to do that I follow this tutorial https://community.linuxmint.com/tutorial/view/877
However there's a problem: when I try to execute
sudo service mdm stopit says
'Failed to stop mdm.service: Unit mdm.service not loaded'.
How to deal with that? Maybe MATE desktop service is now called some other way?
OS: Mint 18.3 Sylvia.
