--- Comment #17 from taijian at posteo.de ---
And that was premature... The second invocation of DRI_PRIME=1 does crash the
system (as in: total freeze, nothing doing except for hard reboot). 

The system starts up OK, power consumption is way down compared to before
(~11W), DRI_PRIME=1 glxinfo triggers the dGPU to on, then it turns off again.
Everything fine so far. But the second invocation causes the system to die, and
this is consistent over several attempts now. So we are making progress, but
are not quite there yet...
