Hello,

 The connector list is wrong on my system (amd A8-3850 with integrated radeon
hd 6550d). My system have got VGA, DVI and HDMI connectors. The VGA connector
is always reported as connected by xrandr (connected or not). I deactivated
this one with kernel parameters video=HDMI-A-1:e video=VGA-1:d. The DVI
connector appears as HDMI-0. The HDMI connector is absent (When I connect a
monitor to this one, HDMI-0 becomes this output and the DVI output is lost). 

Anthony.
