[Videoconferencing] MOB Conference Room screen layout

[Andrew Daviel]

The projector and monitor in the MOB Conference Room now behave like in 
ISAC2 223 - i.e. two independant screens.

If you want an application to run on the projector screen, you start it 
on the projector screen. If you start it on the monitor, it stays there.
The projector screen is "right" of the monitor screen, as in real life. 
Moving the mouse beyond the right edge of the monitor screen will move it 
onto the projector screen

This is now the default and only setting; the machine still starts in 
runlevel 5 (graphical login).

Other possibilities that can be considered are xinerama (you can drag 
things between screens, but sometimes they appear on the projector screen 
when it's off), and, I think, cloned (as before). If there is demand I 
can start it in runlevel 4 (text console) and have startx2, startx2m as 
in ISAC2.

When the machine was upgraded, we chose a dual-head video card but kept 
the xorg driver and VGA splitter used with the old machine. I have 
removed the splitter to use elsewhere and connected both displays 
directly to the card using an Nvidia driver.
