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?
