What's your graphics chip set? That might really be a function of the 
graphics chip set/driver .... :-( Something has to keep the first 
session alive while you create the n-th. And all the programs running in 
all sessions expect `live' display access. So n X-displays require the 
chip set to accept n*load.

Mine in a almost four year old Lenovo W510:

Can you try something?
* In your first X session, can you lock your screen. Do you see an 
option to start a new session on the lock-screen?  I do;-)
