[ltp] External Video on T30

[Ron Joffe]

I have an A31p with a similar configuration. I am using Xinerama to have =
two=20
Displays (thinkapd LCD and an external Display).

Is there an Easy wy for me to switch between my current configuration and=
 a=20
configuration where I am using my LCD (laptop) Display only.

I know I can switch the XF86Config files back and forth, but something fr=
om=20
within X, once it was started would be ideal.

Thanks,

Ron
