Add to linux client ability to blank remote (Guest) screen

The Blank screen option in linux would be great for a new service we offering , where we deploy custom built linux boxes wiht various tools and in-house custom scripts etc on client networks and then access them using Connect-wise Control. When we are working we like to keep the remote system monitor blank so end user/ client does not see what we are doing and protects our intellectual property, etc.

We are currently using Ubuntu as our base Linux OS.
