Aleksei, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following: 1) The one to test is at the very top line at the top of the page (not the daily folder). 2) The release names are irrelevant. 3) The folder time stamps aren't indicative of when the kernel actually was released upstream. 4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .
If testing on your main install would be inconvenient, one may: 1) Install Ubuntu to a different partition and then test this there. 2) Backup, or clone the primary install. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Also, you don't need to apport-collect further unless specifically requested to do so. It is most helpful that after testing of the latest upstream kernel is complete, you mark this report Status Confirmed. Lastly, to keep this issue relevant to upstream, please continue to test the latest mainline kernel as it becomes available. Thank you for your help. ** Tags removed: bios-outdated-1.41 ** Tags added: latest-bios-1.41 ** Changed in: xorg (Ubuntu) Importance: Low => Medium ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- 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/1619668 Title: Brightness is not changed after pluging or restore after sleep Status in xorg package in Ubuntu: Incomplete Bug description: All these happens after 14-->16 upgrade Scenario: 1. let my laptop go to asleep mode after some idle(say 5 minutes) 2. let switch on it by 'power' button 3. monitor's brightness is dark - expected to be normal brightness not that dark 4. if do unplug AC adapter(or unplug from docking station) - monitor's become bright so one can read text ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: xorg 1:7.7+13ubuntu3 ProcVersionSignature: Ubuntu 4.4.0-36.55-generic 4.4.16 Uname: Linux 4.4.0-36-generic x86_64 .tmp.unity_support_test.0: ApportVersion: 2.20.1-0ubuntu2.1 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 Date: Fri Sep 2 16:22:49 2016 DistUpgraded: 2016-08-17 13:31:37,867 DEBUG icon theme changed, re-reading DistroCodename: xenial DistroVariant: ubuntu DkmsStatus: virtualbox, 5.0.24, 3.19.0-66-generic, x86_64: installed virtualbox, 5.0.24, 4.4.0-34-generic, x86_64: installed virtualbox, 5.0.24, 4.4.0-36-generic, x86_64: installed DpkgLog: ExtraDebuggingInterest: No GraphicsCard: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Lenovo 2nd Generation Core Processor Family Integrated Graphics Controller [17aa:21d2] InstallationDate: Installed on 2015-12-17 (259 days ago) InstallationMedia: Ubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805) MachineType: LENOVO 41716PG ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-36-generic root=UUID=14d23f0e-cfcc-40fd-87e2-7ca166c9b29f ro quiet splash vt.handoff=7 SourcePackage: xorg Symptom: display UpgradeStatus: Upgraded to xenial on 2016-08-17 (16 days ago) dmi.bios.date: 04/29/2015 dmi.bios.vendor: LENOVO dmi.bios.version: 8CET59WW (1.39 ) dmi.board.asset.tag: Not Available dmi.board.name: 41716PG dmi.board.vendor: LENOVO dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvr8CET59WW(1.39):bd04/29/2015:svnLENOVO:pn41716PG:pvrThinkPadT420s:rvnLENOVO:rn41716PG:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 41716PG dmi.product.version: ThinkPad T420s dmi.sys.vendor: LENOVO version.compiz: compiz 1:0.9.12.2+16.04.20160801.3-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.67-1ubuntu0.16.04.2 version.libgl1-mesa-dri: libgl1-mesa-dri 11.2.0-1ubuntu2.1 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 11.2.0-1ubuntu2.1 version.xserver-xorg-core: xserver-xorg-core 2:1.18.3-1ubuntu2.3 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.10.1-1ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.7.0-1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20160325-1ubuntu1.1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.12-1build2 xserver.bootTime: Wed Aug 31 22:23:57 2016 xserver.configfile: default xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.outputs: product id 12876 vendor SEC xserver.version: 2:1.18.3-1ubuntu2.3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1619668/+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
