--- Comment #2 from Daniel Vetter <daniel at ffwll.ch> ---
Note that ivb has 3 output pipes, but only two plls. Which means that you need
to select modes with the same dotclock on at least two outputs (VGA and HMDI
here, since LVDS runs at its fixed mode always). It's a hw limitation.

Furthermore you need to run at latest drm-intel-fixes from

http://cgit.freedesktop.org/~danvet/drm-intel

to avoid hitting known bugs with ivb 3 pipe. So please attach xrandr --verbose
and retest with the above kernel so we know whether this is wontfix, already
fixed or a new bug.
