Do you have the latest BIOS?
You could try the latest kernel from the mainline PPA

Seems to use that switching GPU nonsense.

Have you installed Nvidia Prime?

If you want the very latest kernel download the 3 below files to a folder

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9-rc4/linux-headers-4.9.0-040900rc4_4.9.0-040900rc4.201611052031_all.deb

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9-rc4/linux-headers-4.9.0-040900rc4-generic_4.9.0-040900rc4.201611052031_amd64.deb

Then install them all at the same time with:

cd ~/Downloads; sudo dpkg -i *.deb

(i assume you'll just click the links and use default options)

Can you help with this problem?
