Description Rudy Grigar 2009-04-15 02:42:13 UTC 
Description of problem:
Unable to uncheck "Mirror screens" from System->Preferences->Display without creating an xorg.conf with a larger Virtual size.  

Version-Release number of selected component (if applicable):
Fedora Rawhide 2009-04-14
Name       : xorg-x11-drv-nouveau
Arch       : x86_64
Epoch      : 1
Version    : 0.0.12
Release    : 26.20090413git7100c06.fc11

How reproducible:
Always reproducible without an xorg.conf

Steps to Reproduce:
1. Connect two monitors with different default resolutions to an nvidia G80
2. Remove /etc/X11/xorg.conf if it exists
3. Open System->Preferences->Display
4. Uncheck mirror screens and set displays to their native resolutions
5. Click apply
  
Actual results:
An error message is displayed saying: "Could not apply the selected configuration; required virtual size does not fit available size: requested=(2960, 1050), minimum=(320, 200), maximum=(1680, 1680)"

Expected results:
Resolutions are changed as requested: 
Monitor0=1680x1050
Monitor1=1280x720

Additional info:
Adding the following to /etc/X11/xorg.conf fixes the issue-
Section "Screen"
	Identifier "Screen0"
	SubSection "Display"
		Virtual   2960 1050
	EndSubSection
EndSection

Hardware:
GeForce 8800 GTS
22" CTL 1680x1050 (Primary display)
32" MAG 1280x720 (Secondary display/HDTV)

This error is present with and without nouveau.modeset enabled.
