Jaleks' answer was only almost right for me, but this finally worked (Linux Mint 18.2 Cinnamon, manually updated to LightDM (from LM 18.1)):

Install sudo apt install numlockx, after that, edit /usr/share/lightdm/lightdm.conf.d/90-slick-greeter.conf file and add the following line at the end:

greeter-setup-script=/usr/bin/numlockx on
