Yes, you are right, X was unavailable because of this:
With the coming 14.04 release sux (wrapper around su which will transfer your X

because it is being pulled from Debian, because of no maintenance of the 
original code.)

 where an alternative to using the obsoleted sux is given. 
The problem is then solved, thanks.
