I need to configure LightDM, so user could only choose session type which will then start automatically without password. And when he had choosen 'kiosk' session, it should start as quest. When he had choosen 'desktop', then normal session should start for user 'my_user'.
Is it possible with lightdm? probably using scripts?! Or maybe create own greeter?
UPDATE
Please note I don't want do run these session in parallel.
Thank You!
