(Sorry, I thought the debug log would have all that stuff.)
This is a dual-GPU system, with an HD Graphics P530 and an NVidia Quadro M2000M.
 The Intel card is the master, the NVidia card is used as an output slave (i.e.,
my HDMI port is actually connected to the NVidia card).

How can I find that out?  I am using the Mesa drivers for both cards, as far as
OpenGL goes.  (The proprietary NVidia drivers don't support being an output 
slave.)

Fair enough.  The default settings are broken though.

Kind regards,
