[ltp] X config

I don't know if autodetection is possible, and I looked into this issue for
a few hours.  

The simplest thing to do is just add a modeline for the external monitor
into your XF86Config and switch resolutions on the fly with ctrl-alt +/-.
About 1/2 of the time it comes up in the right resolution for the external
monitor, and about half the time I have to cycle through a few modes or
restart the xserver before it works right.  Again, I place the blame on my
funky KVM switch, but it's a small, once-a-day type nuisance at worst.

It would be nice if it auto-detected, though.
