I am running Debian Sid on a laptop machine with an Intel Haswell CPU
with Intel HD 4600 graphics.

When using RandR (xrandr, arandr), I am unable to re-configure my
displays from the one integrated in the machine (eDP1), to three
external displays (in this case, HDMI1 (DP -> DVI via DP++), HDMI2 (HDMI
-> DVI), HDMI3 (miniDP -> DVI); the machine has three external
connectors). I haven't played with DP and multi-stream transport, but I
expect it would behave similarly (that is, annoyingly).
> xrandr: cannot find crtc for output HDMI
My work-around is to issue two RandR requests, with the first one
enabling an external display, and the second one disabling the internal
display and enabling the rest. This is rather annoying and conflicts
with some of the scripts I use to automatically configure my displays
based upon context and hot-plug (autorandr).
The internal display is 1920x1080, and the three external displays are
identical monitors with 1920x1200 resolution. I believe this is key,
and has to do with the number of available PLLs (2) and encoders (3) in
the Intel hardware.
I've attached an strace (xrandr.log) of the xrandr command:
> xrandr \
> --output DP2 --off \
> --output DP1 --off \
> --output HDMI3 --mode 1920x1200 --pos 3120x0 --rotate left \
> --output HDMI2 --mode 1920x1200 --pos 1920x0 --rotate left \
> --output HDMI1 --primary --mode 1920x1200 --pos 0x410 --rotate normal \
> --output eDP1 --off \
> --output VGA1 --off
Any help resolving this issue is greatly appreciated.

Though there is still this logic in check_crtc_for_output:
if (crtc->notput) { // check we can clone in our configuration
...
} else if (crtc->crtc_info->noutput) { // check against old
}
But we never ignore the old configuration when we disable all the
outputs on it. So to avoid running out of CRTC prematurely, we also need
to stop considering the old configuration like:
