Kernel log

The Nvidia 940MX video card is reported wrong (according to the CodeNames page
and other sources such as videocardz). Should be reported as NV118 (GM108), is
reported as NV117 (GM107). GlxGears also reports it as NV117. GlxInfo also
reports it as NV117. Not sure if this brings other problems along.

Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.

Don't trust everything you read online (except this comment). Marketing
names
are always lies. What nouveau reports is what's correct, at least as far as
the
chipset goes.

As an aside, I'd recommend updating mesa, as you're missing compute
shader
functionality.
