The bug appears when switching from kernel version 4.9.0-3-amd64 to 4.9.0-4-amd64, and is still present when I try 4.9.0-5-amd64.
Downgrading to 4.9.0-3-amd64 worked around the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1574617 Title: External monitor keeps going blank To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1574617/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
