Hello, 4.4.0-38 worked perfectly to me.
Steps (for those as noob as me): - Enable "Pre-released updates" at "Software & Updates" from "System Settings". - Open a terminal window and execute: "sudo apt update" and then "sudo apt install linux-generic" Restart. That should do the trick. Thank you Timo Aaltonen for you time and attention. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1553503 Title: multi monitors - black flashes or black screen when the mouse cursor leaves a monitor To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1553503/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
