[LightDM] Triggering LightDM's lockscreen or user switcher

[Nikita Nikishin]

Hello,

I am working on integrating a few DM's into XFCE's logout button. I've found commands to lock GDM and XScreensaver:

    gnome-screensaver-command -l

And:

    xscreensaver-command -lock

Is there a similar way to lock the screen (and maybe switch to the user selection dialog) with LightDM?

Thank you!
