"Switch User" via 'xflock4' i.e. 'light-locker-command --lock'.
From the light-locker and LightDM's greeter perspective,
"Lock Screen" and "Switch User" are the same action type.
Of course, this functionality implies working 'light-locker'.
See "light-locker as additional preferred screen locker"
Better use "dm-tool switch-to-greeter" as replacement for "gdmflexiserver".

'dm-tool' is not intended to be used directly.
If 'light-locker' doesn't run, 'dm-tool switch-to-greeter' will leave the session unlocked.
It is the very reason why there is a tool like 'light-locker' with its controller 'light-locker-command', which will lock the session and then switch to the LightDM's greeter.
I hope you understand this. ;)
