Etienne Papegnies, as per http://www.dell.com/support/home/us/en/19 /product-support/product/optiplex-7440-aio/drivers?os=biosa an update to your computer's buggy, insecure, and outdated BIOS is available (1.7.6). When you update to this following https://help.ubuntu.com/community/BIOSUpdate how does this improve the situation?
For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on how this improves the situation. 3) Please mark this report Status New. If it's not reproducible, please mark this as Invalid. Thank you for your help. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1619556 Title: Video Stacking/Scaling issue on DELL OptiPlex 7440 AIO ( Intel Core i5-6500 Skylake ) Status in xserver-xorg-video-intel package in Ubuntu: Incomplete Bug description: [Description] During video playback a very disturbing bug occurs: the video area is always on top every other window. The video also won't scale when changing the size of the player window. This is not player-specific as both SMPlayer and VLC are affected. The bug doesn't register on screenshots so I had to take a photo of the screen to illustrate: https://ubuntu- mate.community/uploads/default/original/2X/c/ceba93ba6a7025cba79779bd92288cab92e09f3c.jpg Definitively related bug reports: https://bugs.freedesktop.org/show_bug.cgi?id=94559 https://bugzilla.redhat.com/show_bug.cgi?id=1305369 WORKAROUND: - Open SMPlayer, go to Options -> Preferences - Go to "Advanced", then to the "Options for MPlayer/mpv" tab - add -vo gl to the (empty) option list --- ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 BootLog: /dev/sda1: clean, 379773/2445984 files, 2321044/9764864 blocks CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: MATE DistUpgraded: Fresh install DistroCodename: xenial DistroRelease: Ubuntu 16.04 DistroVariant: ubuntu EcryptfsInUse: Yes ExtraDebuggingInterest: Yes, if not too technical GraphicsCard: Intel Corporation Sky Lake Integrated Graphics [8086:1912] (rev 06) (prog-if 00 [VGA controller]) Subsystem: Dell Skylake Integrated Graphics [1028:06c5] InstallationDate: Installed on 2016-07-07 (59 days ago) InstallationMedia: Ubuntu-MATE 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 413c:2113 Dell Computer Corp.
