From what I can tell, the rules of engagement are a bit more complex than
that. Something like:
* Xorg (only) detects the presence of monitors and their capabilites (Plug n
Play) when it starts up.
* If xorg can't detect a 2nd monitor, then no dual-head etc for you. (external
VGA for a laptop is typically treated as a 2nd monitor).
* Some cards (nvidia I think) don't pass the monitor info on correctly.
* If xorg can't detect the capabilities of a Plug n Play monitor, then it
assumes some safe low-end values which are almost always no what you want.
Best advice is to start Xorg (read: boot time, or manually restarting Xorg)
with any external monitors plugged in and turned on. And to manually select
the monitor type you have in system settings instead of relying on Plug n
