I also have this problem, and I don't think it's a duplicate: * The entire external screen turns black intermittently * The background image is not affected * The laptop screen does not flicker Please reopen this bug. The issue was already fixed in 16.04 by updating to the 4.6/4.8 kernel, unfortunately it seems to pop up again after upgrading to 16.10. I updated to Kernel 4.8.4 and 4.8.0-997, which both don't solve 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/1634449 Title: Black flicker when leaving monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1634449/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
