FYI, I needed overlayfs and so had to interrupt my 4.3.0-040300-generic (#201603101009) testing and booted into 4.4.0-12.28. 4.4.0-12.28 has the bug.
I am back in 4.3.0-040300-generic (#201603101009) now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1547619 Title: Intermittent screen blinking with 4k external mini display port with 4.4 kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1547619/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
