--- Comment #4 from Matt Roper <matthew.d.roper at intel.com> ---
If I'm understanding your term "Nvidia Optimus" properly, I think you want your
applications to render with your NVidia GPU, but for the output to show up on
the monitors attached to your Intel display controller?  From the X log you
attached it doesn't look like you have any X driver managing the Intel display
right now, which would explain why you're not seeing your displays light up.

Can you post your config file?  Based on the X log, X is only trying (and
failing) to load the nouveau driver; neither the modesetting DDX (which uses
the glamor acceleration method) nor the intel DDX (which would use either UXA
or SNA acceleration methods) show up in your log.  It also looks like there may
be some permission issues where the DDX drivers don't have the permission they
need on the /dev/dri/card{0,1} device nodes.
