Thank you for reporting this bug to Ubuntu. Ubuntu 16.04 (xenial) reached end-of-standard-support on April 29, 2021.
See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in. You've reported a Xorg issue on code that hasn't changed since Fri, 04 Mar 2016 16:53:04 +0200. I've marked this bug as incomplete. You can try support, but with 16.04 in ESM, support options are fewer. If you believe I'm in error, you can leave a comment outlining why & change the status back to 'New'. ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1982113 Title: My screen is horizontally divided into two parts.
