Christopher M. Penalver,
- I tried to reproduce the problem after login with GNOME Flashback (Metacity) for 2 days. I tried many things, but without success, everything worked perfectly. - By awakening with Unity, the display comes back during one second, then every time becomes black again during another second, and then stays on with or without the blinking problem of parts of the screen. With Metacity, as a normal behavior, the screen does not become black again during one second, and the display is immediately good, as expected. The screen becoming black again is not normal and is a sign for a not mastered screen processing, pieces of code taking their liberty for undesirable results. - I have noticed that the problem has more chance to occur after opening and closing several windows, and switching between them. Again today. - It is possible that the problem appeared with the kernel release which began to manage Intel graphic cards. I remember, without warranty, having feared the worse at that moment, _before_. Since, perhaps with Unity a crazy process is remaining on awakening. Pierre Wilch Le 16/02/2018 à 01:20, Christopher M.

On awakening, for example by using the shift touch, parts of the screen are blinking according to 1 second rate and 3 seconds cycle. Coming back to normal behavior needs to close and re-open windows. To help to reproduce: - edit a message with thunderbird; - select ubuntu "parameters"; - select "Luminosité & verrouillage" ("Brightness & keyboard locking"?); - select "1 minute"; - wait 1 minute and going into sleep state; - when in sleep state press the "shift" key; and then I have a blinking "Christmas tree", too complicated to be described. I tested it again 3 times why writing this post (firefox had also an opened window, under thunderbird; with firefox alone, the screen blinks only one time -should also not-). WORKAROUND: When the seconds are not displayed in the upper bar there is no problem. --- .tmp.unity_support_test.0: ApportVersion: 2.20.1-0ubuntu2.15 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity DistUpgraded: Fresh install DistroCodename: xenial DistroRelease: Ubuntu 16.04 DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0156] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Toshiba America Info Systems 3rd Gen Core processor Graphics Controller [1179:fb31] InstallationDate: Installed on 2017-06-29 (223 days ago) InstallationMedia: Ubuntu 16.04.2 LTS "Xenial Xerus" - Release amd64 (20170215.2) MachineType: TOSHIBA SATELLITE PRO C850-1GR Package: xorg 1:7.7+13ubuntu3 PackageArchitecture: amd64 ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.13.0-32-generic.efi.signed root=UUID=7169ec32-1674-4c34-b45b-2001ed412887 ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 4.13.0-32.35~16.04.1-generic 4.13.13 Tags: xenial ubuntu compiz-0.9 Uname: Linux 4.13.0-32-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 10/01/2013 dmi.bios.vendor: Insyde Corp. dmi.bios.version: 6.80 dmi.board.asset.tag: Type2 - Board Asset Tag dmi.board.name: PLCSF8 dmi.board.vendor: Intel dmi.board.version: Type2 - Board Version dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: OEM Chassis Manufacturer dmi.chassis.version: OEM Chassis Version dmi.modalias: dmi:bvnInsydeCorp.:bvr6.80:bd10/01/2013:svnTOSHIBA:pnSATELLITEPROC850-1GR:pvrPSCBXE-01T01GFR:rvnIntel:rnPLCSF8:rvrType2-BoardVersion:cvnOEMChassisManufacturer:ct10:cvrOEMChassisVersion: dmi.product.family: Type1Family dmi.product.name: SATELLITE PRO C850-1GR dmi.product.version: PSCBXE-01T01GFR dmi.sys.vendor: TOSHIBA version.compiz: compiz 1:0.9.12.2+16.04.20160823-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.83-1~16.04.1 version.libgl1-mesa-dri: libgl1-mesa-dri 17.2.4-0ubuntu1~16.04.4 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 17.2.4-0ubuntu1~16.04.4 version.xserver-xorg-core: xserver-xorg-core N/A version.xserver-xorg-input-evdev: xserver-xorg-input-evdev N/A version.xserver-xorg-video-ati: xserver-xorg-video-ati N/A version.xserver-xorg-video-intel: xserver-xorg-video-intel N/A version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau N/A To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1739322/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
