You need to grant 'root' access to your system by giving them access to
a suitable shared key with the right privileges.

Read the 'Xsecurity' manual page for more details on how to do this; the
short form is to add their ~/.Xauthority file to your server for local
connections, pretty much.[1]

Alternately, write a little script that does 'su - <user> -c "xdpms
off"' for the right value of '<user>' to have access. :)

Footnotes: 
[1]  This means that anyone who can read that file can access your X
     session with full control, so do take care about it.
