Because we do not yet officially support hybrid graphics in Ubuntu (esp.
involving the proprietary drivers), I do not think it is time effective
for you to continue testing this particular hardware configuration. I
would suggest instead manually switching off the intel device (how to do
this varies by hardware vendor; some you can do it in bios, others have
a toggle switch, others need kernel tweaks or busid settings... google
around a bit and you should find some docs, or ask on askubuntu.com),
and then test -nvidia in isolation.
Thanks again for providing such a well written test report. I hate that
this is probably not the news you hoped to hear, but at least I can say
the need for better hybrid graphics switching support is very widely and
well known, and I'm hopeful in a release or two we'll start to see
better support for it.
