Some newer laptops have dual GPUs, an onboard Intel combined with one from
another vendor for higher performance. There's hot-switching between the
two, but AFAIK it's not supported in FreeBSD. There may be a BIOS option
to disable one or the other. There should still be two video outputs.
More than one video card at a time is a different issue, which is also
unsupported on FreeBSD AFAIK:
(WW) VGA arbiter: cannot open kernel arbiter, no multi-card support
It appears that it is something that needs to be resolved pretty quickly
then. The linux guys jumped on it quick as (I'm not ribbing by the way) -
probably their guys came across it sooner than BSD users.
What has thrown me is the fact that I didn't even consider it as a problem
because I already had installed on a dual video system- ATI card and NVidia
onboard, both that will work on a linux system, and that FBSD has no problem
like this either; it just works. Weird...
It's difficult to tell what you're saying. It's possible that multiple
cards would work in some combinations, and just that the ones I tried
did not. Also, you're talking about two systems, a laptop and a
desktop. So it would be good to get some specifics, like laptop brand
and model, whether the desktop dual-card setup worked with FreeBSD (and
which version of FreeBSD).
