Aleksei, as per http://support.lenovo.com/us/en/products/Laptops-and- netbooks/ThinkPad-T-Series-laptops/ThinkPad- T420s?tabName=Downloads&linkTrack=Mast:SubNav:Support:Drivers%20and%20Software|Drivers%20and%20Software&beta=false an update to your computer's buggy, insecure, and outdated BIOS is available (1.41). 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. ** Tags added: bios-outdated-1.41 regression-release ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** 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 2 cases here: 1. when plug at a dockstation(lenovo t420s) brighness is not chaged(remains too dark) 2. when plug in adapter - the same 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
