Same issue here on a Dell Latitude E5470. OS: Ubuntu 16.10 Kernel: 4.8.0-22-generic CPU: Intel(R) Core(TM) i7-6600U CPU @ 2.60GHz GPU: Intel Corporation HD Graphics 520 (rev 07) Xorg (package version): 1:7.7+13ubuntu4

To get rid of it, I had to full screen something. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
