** Description changed: I experience the following bug after updating Ubuntu 14.04. on a Dell Latitude Laptop for Hardware Enablement Stack some days ago: Dual Monitor Screen: When the mouse cursor leaves one of the screens, there is either : - no problem - the screen becomes black just below the position of the cursor and instantly comes back to normal. - the screen becomes entirely black with some random colored pixels flickering on the far left of the screen. I have to move the cursor to the black screen, otherwise it stays black. After the update my kernel version is 4.4.0-36-generic, and my Ubuntu is Ubuntu 14.04.5 LTS Thank you, Janek Greskowiak ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-4.4.0-36-generic 4.4.0-36.55~14.04.1 ProcVersionSignature: Ubuntu 4.4.0-36.55~14.04.1-generic 4.4.16 Uname: Linux 4.4.0-36-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.21 Architecture: amd64 CurrentDesktop: Unity Date: Sat Sep 3 19:03:09 2016 InstallationDate: Installed on 2016-02-27 (189 days ago) InstallationMedia: Ubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805) SourcePackage: linux-lts-xenial UpgradeStatus: No upgrade log present (probably fresh install) + --- + ApportVersion: 2.14.1-0ubuntu3.21 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: janek 2059 F.... pulseaudio + CurrentDesktop: Unity + DistroRelease: Ubuntu 14.04 + HibernationDevice: RESUME=UUID=53d29794-1a88-491c-a81d-a8ad51c9e77c + InstallationDate: Installed on 2016-02-27 (189 days ago) + InstallationMedia: Ubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805) + Lsusb: + Bus 002 Device 003: ID 0a5c:5800 Broadcom Corp.
