I've since discovered that there are two keys to having a "panoramic"
display. You must have Xinerama enabled (either Option "Xinerama" "true"
in ServerFlags or in ServerLayout) and you must use the *same* BusID for
both devices (if you have one video card.)
Hope this helps someone.
I'm still having the problem with the second monitor. When you first start
X it doesn't display anything but its light is green (indicating that it's
getting a signal.) After a while, it suddenly starts working (seems like
after power saving is invoked and the first monitor goes blank.) I'm not
seeing any error messages in the console log, messages or Xorg.0.log that
seem to point to the cause of this problem.
If anyone has any hints, I'd appreciate it.
