Comment 88 for bug 362582

If I attach an external monitor to the VGA connector, then it is recognized by xrandr, but I have not yet been able to enable the external display.

xrandr -q

xrandr --auto
xrandr: cannot find crtc for output VGA

system-config-display draws a thin blue line and then the LVDS display
is covered with a slowly changing greyish pattern, probably because the internal display is driven with a too high refresh rate.

If I boot the S6010 with an external monitor attached, then the internal display shows again the slowly changing greyish pattern.

So having dualhead working needs some more effort. Any hints on how to proceed would be appreciated.
