[ltp] Using T41p for Presentation over Projector

[Nick Bower]

I have your experience.

To run separate resolutions for the case when using with laptop or when
using external monitor, I need to start X up separately with the monitor
connected or disconnected.  This determines the startup resolution - if
monitor is attached at start, the LCD is smaller and acts as a scrolling
viewport.  If it is not attached at start, then the monitor inherits the
lower resolution of the LCD.  And if this external device is a fixed
resolution device (eg LCD, projector) this has unpredictable
consequences because you're not driving it correctly.

Ideally you'd have X zooming hotkeys without starting X each time, but
this doesn't seem to work for me (Mandrake 10 / X 4.3).
