Hello everybody,

jkwong888 at https://github.com/Bumblebee-Project/Bumblebee/issues/580
came up with a fix that actually solves the problem - at least for me.

Turns out that appending the following screen-section to
/etc/bumblebee/xorg.conf.nvidia makes bumblebee work:

Section "Screen"
    Identifier "Default Screen"
    Device "DiscreteNvidia"

After a restart of bumblebeed, optirun works properly.
