I saw a new kernel in xenial with intel fixes so I decided to try it. This kernel has the bug: $ cat /proc/version_signature Ubuntu 4.4.0-9.24-generic 4.4.3
I'll try the bisected kernel 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
