Red Hat Bugzilla – Bug 426396
No dual screen on a 24 inch white iMac
Last modified: 2008-06-05 08:33:16 EDT
Description of problem:
I have a 24 inch white iMac with a nVidea 7300. Everything works fine, but when
I plug in an external monitor through the miniDVI port I get no picture on the
external monitor. Also, if I use system-config-display to try to activate dual
screen it correctly identifies the external monitor but does not display
anything. Instead the resolution on my built in monitor changes to the
resolution of the external monitor. The only way to fix this problem is to
remove the cable between the external monitor and the computer. Then the
resolution of the built in monitor returns to normal.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Plug in external monitor.
2. Get no picture on external monitor.
3. Try to fix things with system-config-display and bork your settings.

Don't really know what this is....
I have tried this on the F9 beta and I get the same results. Do you want the
same files again?
Actually, yes please -- F9 beta was totally rewritten, so things are different
(albeit still broken for you :().

Still broken in the latest rawhide...
Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:
-nv doesnt support dualhead on this card and never will...
You could try nouveau.. the F10 package might work good.
Is that nouveau for Fedora 10 you mean?
There is nouveau in Fedora since at least Fedora 8. xorg-x11-drv-nouveau
