Public bug reported: Sometimes, when moving cursor from one monitor to the other, the external monitor turns black and gets back on again.
The hardware is Dell Latitude E5470 with Docking Station and monitor connected via DisplayPort (checked both ports and happens on both of them). Everything worked correctly on Ubuntu 16.04, but it happens on Ubuntu 16.10. Kernel 4.8.0-25-generic. The bug isn't related to cursor only, if focus changes by alt+tab it sometimes happens as well. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1553503 This is the same bug as this one, but closed. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
