[SATLUG] Dual Monitors with FC6

[Gabriel Doss]

I don't use ATI or a laptop, but I do have dual monitors using FC6 using an
nVidia card. Screen0 needs to be linked to something. Try specifying the
laptop monitor as Monitor0. It would default to that with only one monitor
so you don't need it in the single-head config.

To sum up, add a: "Monitor" "Monitor0" line to Screen0. Also add a monitor
device identified as "Monitor0." Use the specs of your laptop monitor for
that. I'd also edit xorg.conf by hand as I've never had
system-config-display work when attempting a dual monitor setup. There are
just too many variables that it does not account for.

The other thing you may want to check is if the ati driver can handle dual
monitors. You may need the proprietary fglrx driver. I have no idea whether
it can or cannot, just may be something you want to check.

And good luck. Trial and error is how I got mine to work. I've had to redo
my xorg.conf file many times as I make hardware and other changes, and it is
usually a struggle.
