I have this issue on a W530, Ubuntu 16.10, using either NVIDIA binary driver V367.57 (proprietary) and V370.28 (open source).
What works: Built-in display only. 2nd display only. Mirrored display. Nouveau driver with built-in AND 2nd display. ** Attachment added: "IMG_20161027_105742.jpg" https://bugs.launchpad.net/unity/+bug/1404147/+attachment/4768188/+files/IMG_20161027_105742.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1404147 Title: Screen is stretched when using dual monitors To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1404147/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
