I am not able to reproduce this consistently but it does occur frequently. What happens is my second monitor will go black for a few seconds and then return to normal. This will happen a few times an hour. The monitor on my laptop will be fine.
One more detail I am connecting to the second monitor through a Lenovo docking station. ** Summary changed: - Screen flickering + Screen flickering on second monitor ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1572667 Title: Screen flickering on second monitor Status in xserver-xorg-video-intel package in Ubuntu: Confirmed Bug description: Ubuntu Gnome 16.04 RC.
