I am trying to get dual head on ATI FirePro M5800 working. LVDS works,
but VGA-0 is in power save mode no matter what I do.
My colleague got the non-free driver working, but I would prefer using
the free driver. My research seems to indicate the chipset is called
Redwood or r8xx or RV830 or r800 or Evergreen - but I could be wrong.
I have been unable to find a guide for this card and the obvious
(xrandr --output LVDS --output VGA-0 --left-of LVDS) does not work.
Neither does KDE's gui config of display.
Below is some output that may help.
