xorg log radeon.modesetting=0, dualhead enabled

Dual head was enabled with gnome display settings.

How it works now
Default setting was Mirror. After I unchecked the mirror, I had to set the
virtual size in xorg.log, so I uncommented those lines. Then I could set both
screens properly, with each one being labeled by their names (HP and Philips,
respectively).

How it works under KMS
The same exercise, only on both screens it said Philips and both displays were
behaving as "right of".
