The key lines in the xorg log are near the bottom, I suspect:
(II) RADEONHD(0): Output VGA_1 using monitor section Sony
(II) RADEONHD(0): Output VGA_1 has no monitor section
(II) RADEONHD(0): Output DVI-D_1 has no monitor section
(II) RADEONHD(0): EDID for output VGA_1
(II) RADEONHD(0): EDID for output DVI-D_1
(II) RADEONHD(0): Output VGA_1 disconnected
(II) RADEONHD(0): Output DVI-D_1 disconnected
(WW) RADEONHD(0): No outputs definitely connected, trying again

Then there is a bit of a backtrace at the end, of course.
