John Morris, to clarify, you upgraded the OS whose hardware is the NUC5i5RYB (not some other computer with different parts) and this is reproducible?
To advise, it's much easier to deal with different hardware that has similar/same symptoms if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal: ubuntu-bug xorg Also, please feel free to subscribe me to it. For more on why this is helpful, please see https://wiki.ubuntu.com/ReportingBugs. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1535447 Title: Intel Graphics 4K Screen Tearing Status in xorg package in Ubuntu: Incomplete Bug description: On a fresh boot all works well, but after an indeterminate amount of time the screen starts tearing badly, most noticeably as a permanent vertical tear. Once this tearing starts, it affects everything (desktop, etc) but is mostly visible in videos. The only way to get rid of the tear is to reboot. I do not know where this tearing is occurring, compositor? graphics driver? Hardware, Intel NUC5i5RYK (integrated graphics), LG 31MU97 DCI 4K monitor (4096x2160). Using a Mini DisplayPort to HDMI cable between the NUC and monitor. 00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09) Software, Kubuntu 15.04 I also see the same problem in 15.10, but the computer I took the video of has 15.04 installed. The screen resolution is set to 4096x2160. In my syslog, I also see tons of these error messages (I dont know if they are related to the tearing). The error message repeats multiple times, and then stops. [ 668.879288] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)! I am hoping I can attach a video to this file which shows the tearing (5.7MB) --- ApportVersion: 2.17.2-0ubuntu1.8 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: KDE DistUpgraded: Fresh install DistroCodename: vivid DistroRelease: Ubuntu 15.04 DistroVariant: kubuntu DkmsStatus: virtualbox, 4.3.34, 3.19.0-43-generic, x86_64: installed virtualbox, 4.3.34, 3.19.0-47-generic, x86_64: installed ExtraDebuggingInterest: No GraphicsCard: Intel Corporation Broadwell-U Integrated Graphics [8086:1626] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Intel Corporation Device [8086:2057] InstallationDate: Installed on 2016-01-12 (13 days ago) InstallationMedia: Kubuntu 15.04 "Vivid Vervet" - Release amd64 (20150422) Package: xorg 1:7.7+7ubuntu4 PackageArchitecture: amd64 ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.19.0-47-generic.efi.signed root=UUID=cfabd4b7-56e6-40a7-a43a-315a7389748e ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.19.0-47.53-generic 3.19.8-ckt10 Tags: third-party-packages vivid kubuntu UdevLog: Error: [Errno 2] No such file or directory: '/var/log/udev' Uname: Linux 3.19.0-47-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 12/22/2015 dmi.bios.vendor: Intel Corporation dmi.bios.version: RYBDWi35.86A.0353.2015.1222.0947 dmi.board.name: NUC5i5RYB dmi.board.vendor: Intel Corporation dmi.board.version: H40999-502 dmi.chassis.type: 3 dmi.modalias: dmi:bvnIntelCorporation:bvrRYBDWi35.86A.0353.2015.1222.0947:bd12/22/2015:svn:pn:pvr:rvnIntelCorporation:rnNUC5i5RYB:rvrH40999-502:cvn:ct3:cvr: version.compiz: compiz N/A version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.60-2 version.libgl1-mesa-dri: libgl1-mesa-dri 10.6.0-~0intel1 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 10.6.0-~0intel1 version.xserver-xorg-core: xserver-xorg-core 2:1.17.1-0ubuntu3.1 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.9.0-1ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.5.0-1ubuntu2 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917-1~exp1ubuntu2.3 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.11-1ubuntu2build1 xserver.bootTime: Tue Jan 26 08:36:27 2016 xserver.configfile: default xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.outputs: product id 38 vendor AJA xserver.version: 2:1.17.1-0ubuntu3.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1535447/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
