[ILUG] Changing btwn laptop screen & monitor

[Brady, Padraig]

Switching between the laptop and external monitor
is done in hardware and X knows nothing about it.
More likely what's happening is that X is setting
a refresh rate/resolution on the card that the 
monitor can't handle. Will need a little hacking 
of Xconfig or &/or startx parameters.
