ah, i do use MetaModes in my xorg.conf, but I didn't realize you could
mix non-dual modes with dual ones. Thanks, this should work for what
i'm trying to do.
However, i may have discovered a little problem with SDL here? I think
there should be a way to choose the display. or is this just a strange
problem with my system, where SDL doesn't heed the DISPLAY variable
(environment variables seems to be SDL's style for this kind of
thing)? maybe i'll look through some source and possibly come up with
a patch, if i'm not lazy.
