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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1572667 Title: Screen flickering on second monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1572667/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
