Description of problem:
I have an nvidia card with both a digital and analog out, one for each screen.
Installing FC4T1 gives me two screens that are identical.
I ran system-config-display to setup dual head, and this fails.
It failed so badly that I resorted to unpluggin the dvi cord, and running system-config-display --reconfig. That failed too.
I'll attach the output from lspci and dmesg.
It would be really good if this worked - I'm not using the binary nvidia driver.
It would also be good to have a --failsafe option that gives people a low res usable screen on one monitor.
If you need anything else for this, let me know!

..and here are the errors from the X server.
Sorry for all the attachments.
Any possiblity of some help on this one?
This will have to be punted to FC5 along with all the other dual head bugs.
Fair enough. It's not exactly a quick fix.
Mass update: move dual head bugs from FC5 to FC6, no way they can get fixed
before FC5 release at this point.

Oops, nvidia card.
The nv driver has no support for dual-head at all, so there's not really any way
to fix this within system-config-display. It's been a requested enhancement
with Xorg for a while now, but no one has stepped up to do it.
We should at least be smart enough to refuse to attempt dualhead setup on nv though.
Update version according to the latest comments.
I'm kicking this to the nv driver for lack of dualheadedness. s-c-d UI
deficiencies are covered elsewhere.

F7 now has rudimentary dualhead support for G70 and below, and RANDR 1.2
dualhead support for G80 cards.
