I also tried also attaching two external monitors (via docking station with one VGA and one DVI port). Clone mode works but when I try to set multihead it states that it lacks CRTCs. I found on the web that disabling SVIDEO output (xrandr --output TV_SVIDEO --off) should help by freeing one CRTC but it did not. Is it a radeonhd, RandR or hardware limitation?
Cannot say without your Xorg.0.log or 'xrandr --prop' output. But it could be that both ports are attached to the same output, then only clone is possible.
It looks like the outputs differ (attachment) and I can turn off single port on docking station without turning of another.
Ah. So this is a DVI-D only. Ok, I assume you do not have a recent
xrandr installed - I fixed several bugs in it in November, so you have
to fetch a recent git version.
