Still a problem in Xenial 16.04. I'm using Intel gfx driver so based on others using different video drivers (ati, nouveau and now intel) may indicate the problem lies at least not with the video drivers.
Perhaps it's a problem with Unity's lockscreen? ** Changed in: unity (Ubuntu) Status: Expired => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1301125 Title: Lock screen after idle time freezes unity To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1301125/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
