well, that was cool, and I am learning from this. Unfortunately those
are device-specific options, and my machine uses the neomagic driver,
which doesn't accept any of these. Nonetheless: I have a
quasi-functional xorg.conf! I have done the following:
define a second monitor "External Monitor" with a very basic configuration.
define a second screen "VGA Out", again with a minimal configuration,
mostly copied from my default screen
add the line:
Screen "VGA Out" do my default X layout.
Now I can switch back and froth between the two using the BIOS toggle
key (fn-F7 for me).
As far as I can tell, this works as long as I don't start up a second
xsession on another vt. Since I was using multiple sessions to test
my xorg.conf, this caught me off-guard... Only discovered my error by
accident. I'm not sure what the origins of this error are, but for
now I am happy. No doubt I will discover other bugs in due time...
Thanks much everyone!
