[Bug 36461] Re: XOrg dualhead regression

[kickaha]

I have been experiencing system lockups with dual-headed configs also. This is a show-stopper for me, unfortunately.
My setup uses
1 x ATI radeon QD AGP video card
1 x ATI radeon VE PCI video card
So my setup is not multi-vendor.
If I set the drivers to 'ati' or 'radeon', the system locks up as the cards initialize. If I set the drivers to 'vesa', on the primary (AGP) I get an 'unsupported video mode' box, and on the secondary, it just doesn't initialize.

/var/log/Xlog.0.log available on request.

Xorg.conf sections:

Section "Device"
  BoardName    "Radeon QD"
  BusID        "1:0:0"
  Driver       "ati"
  Identifier   "Device[0]"
#  Screen       0
  VendorName   "ATI"
EndSection

Section "Device"
  BoardName    "Radeon VE"
  BusID        "2:6:0"
  Driver       "ati"
  Identifier   "Device[1]"
#  Screen       0
  VendorName   "ATI"
EndSection

Section "ServerLayout"
  Identifier   "Layout[all]"
  InputDevice  "Keyboard[0]" "CoreKeyboard"
  InputDevice  "Mouse[1]" "CorePointer"
  Option       "Clone" "off"
  Option       "Xinerama" "on"
  Screen       "Screen[0]"
  Screen       "Screen[1]" RightOf "Screen[0]"
