xrandr for main display
It's me again ;)
I have a Lenovo T430 with "Optimus"--HD4000 + Nvidia. Previously, I was able to
use intel-virtual-output to enable using displays connected to the Nvidia chip.
However, in a recent update (relatively recent--last months--can't say for
sure) this has ceased to work, with the displays showing as not connected.
This is the same laptop/setup as

title="RESOLVED FIXED - intel-virtual-output virtual screens behaving strangely."
href="show_bug.cgi?id=76146">https://bugs.freedesktop.org/show_bug.cgi?id=76146</a>
I would expect things to work as before:
1) Boot the laptop
2) run 'intel-virtual-output'
3) attach laptop to dock
4) xrandr / turn displays on.
however, at step 4, the additional displays/modes are not available, and the
devices show as disconnected.</pre>
