I do not need to be able to move open applications from one screen 
(monitor) to the other. I start them on the screen (monitor) where I 
wish to use them. And YES I can copy/paste data from an application on 
one monitor to an application on the other - I do this all the time. I 
routinely copy data from an application on one monitor on the host to a 
virtual machine running on the other monitor.

When I first created my separate X screens the second monitor did not 
have panels. I created them and added the launchers for the applications 
which I intended to run on that monitor.

System; Preferences; Hardware; Display does NOT provide a way to 
configure the monitors in away to accomplish these things (Ubuntu 9.10, 
10.04, 15.04, CentOS 7, CentOS 7).

I appreciate all of the input folks are providing. However, I asked the 
simple question if separate X screens could be configured on Intel 
integrated graphics.  The discussion seems to have degenerated into "you 
don't want to do" what I wish to do and "you should try something else."

PLEASE if someone knows the answer YES or NO - tell me. If the answer is 
no I will reserve the Intel graphics machines for single monitor or 
headless use and use my Nvidia machines for dual hear use.
