[ltp] Moving Video Won't Display on External Monitor of Thinkpad R32

[morpheus]

Hi,

I'm running FC1 kernel 2.4.22-1.2188.nptl, I've looked everywhere
(including the archives of this site) to find out how to display video
on the external monitor under Linux.

Currently, I can use my internal LCD and external monitor
simultaneously, but for some reason video files (.mpg, .avi, etc.) only
display on the internal LCD.  For example, if I run mplayer to watch a
movie, I can see it on the internal LCD but the external display shows a
black square.  Everything else (graphics, etc.) displays fine.

Under Windows, when this happens, there's a setting in the display
driver properties to make the external display the PRIMARY display. 
This solves the problem.  Is there any way to do this from Linux?
