xorg.conf dual-head Xinerama from Fedora 7

This is the manual xorg.conf I tried which works fine in Fedora 7.  The F8
s-c-display automatically generated one had problems with BusID's when enabling
dual-head.

Xinearama isn't supported, yes I know we shouldn't crash I'll try and make it do
something nicer...

For dual-head you should just be able to use the xrandr command to set stuff..
Comment 4 Dave Airlie 2007-11-30 03:32:47 UTC 
Okay the crashing should now be fixed in updates-testing

You still won't get xinerama but at least it won't blow up if you try... the ATI
driver now uses randr-1.2 to configure things.
