[ltp] External LCD monitor

[D. Sen]

I guess that would work except for the fact that I havent had much luck 
in customizing my desktops (in my window manager) such that the 
icons,etc have relative positions rather than absolute positions. Thus, 
for instance, if I have a task bar at 1400x1050 at the bottom of the 
screen, then switching to the higher resolution usually results in the 
task bar being positioned at 150 pixels higher than the bottom of the 
screen.

The second problem is that X does have problems with these latest 
thinkpads in switching between internal and external screens. Currently, 
I am using a slightly modified X (thanks to one of the radeon 
developers) that lets me have both an external and the LCD screen 
simultaneously. However it doesnt let me cycle through the usual Fn+F7 
(LCD on + CRT on, LCD off+ CRT on, LCD on+CRT on) modes.
