[Romano Giannetti <romano.giannetti@xxxxxxxxx>]

I had this problem with a Dell desktop; It was especially bad with the
second monitor, which blanked out every time it lost focus. I can
confirm that

- $ apt-add-repository "deb http://ppa.launchpad.net/canonical-kernel-team/ppa/ubuntu yakkety main"
- $ echo -en "Package: *\nPin: release o=LP-PPA-canonical-kernel-team-ppa\nPin-Priority: -1\n" >> /etc/preferences.d/canonical-kernel-team-ubuntu-ppa-yakkety
- $ apt update
- $ apt install linux-image-extra-4.6.0-6-generic linux-headers-4.6.0-6-generic linux-tools-4.6.0-6-generic

after having created the directory /etc/preferences.d manually, and so
upgrading to the yakkety kernel, fixed the issue.

Can anyone please post the instruction to revert this and go back to
normal Xenial kernel release when the bug is fixed there? Thanks!
