Correct way to stop/start lightdm ?

[weha]

Kubuntu 13.04.

In the past one could use sudo service kdm stop, or to restart, sudo service kdm restart && exit

What is the correct command now for lightdm ?

I upgraded without problems to 13.04 via tty terminal. In the past I always stopped kdm before
doing the release upgrade. I didn't do it this time as not sure of the command.

Should be:

sudo stop lightdm

and

sudo start lightdm

Oh, thanks Snowhog.
