Thanks, Anthony. Very informative.

I decided to put the second monitor on top. I find that a little less counterintuitive.

But there are still a bunch of problems.

* For starters, the whole thing will not survive a reboot. It all becomes one big mess. 
* The second monitor takes on the duties of the first monitor.
* The second monitor always has the wrong resolution until I add it manually with xrandr.
* Both monitors have a desktop area, with icons. I had never seen that happen!
* Windows will no longer remember that usual, correct position, even if most of them have their position forced by openbox.
* The top position is all wrong. I open arandr and discover that the two screens are superimposed rather than one on top of the other. I have to adjust it back manually on randr.
* The desktop area still looks all messy. In fact, my efforts are useless until I turn off the second monitor, turn it on again, then I can rearrange everything with some hope of putting everything back in its place.
* After everything is in place, many new windows still ignore the "force position" directives in my lxde-rc.xml file and pop up wherever the heck they want.
* With every new rearrangement, osdsh decides to position itself in some new random spot.
