Just had time to test the "gamma fixes" and I can verify that this behaviour is
fixed with commit:
d36c9542d2bd707838a87c451bf76f091aaf5cba
sna: Fix gamma query to not request uninitialized values
Then I tested the latest git version (ccf0fdd) with regard to the remaining
problem - that HDMI output doesn't get detected.
Therefor I've created new dmesg and X logs, which I'll attach (and obsolete all
the others). Additionally, I've disabled my randr client to get a more clear
view on what's happening. Within the logs you can see a time gap at the end.
There, I've waited a few seconds and called `xrandr` (at round about
uptime=61.29).

Nit-pick: it's an application using a self written c++ library with a none
blocking API and that library uses xcb. ;)</pre>
