Can't stop MATE desktop service

[Quipex]

Good day everyone,

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 stop it 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?

"mdm" has probably changed to "lightdm".

In any case you can do

Code: Select all

ps aux | grep dm 

and see which is running.
