apport information ** Tags added: apport-collected has-workaround hirsute reproducible single-occurrence ubuntu
** Description changed: The keys marked for brightness control on the keyboard are supposed to be Fn+F5 (down) and Fn+F6 (up). But pressing them does not have any effects. Volume control keys Fn+F1 (off), Fn+F2 (down), Fn+F3 (up) all do work, and KDE shows appropriate indicators when they are pressed. I know this is a popular problem with Lenovo laptops. I use Ubuntu 21.04 Hirsute on built-in NVMe, but Ubuntu 20.04 booted from USB flash drive also does not allow me to control screen brightness. Hardware and OS information will be collected on Apport request and attached here. + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu55 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: mwg 1006 F.... pulseaudio + mwg 1010 F.... pipewire-media- + /dev/snd/seq: mwg 1005 F.... pipewire + BootLog: + + CasperMD5CheckResult: skip + CompositorRunning: None + CurrentDesktop: KDE + DistUpgraded: Fresh install + DistroCodename: hirsute + DistroRelease: Ubuntu 21.04 + DistroVariant: ubuntu + ExtraDebuggingInterest: I just need to know a workaround + GraphicsCard: + Intel Corporation Iris Plus Graphics G1 (Ice Lake) [8086:8a56] (rev 07) (prog-if 00 [VGA controller]) + Subsystem: Lenovo Iris Plus Graphics G1 (Ice Lake) [17aa:3fd9] + HibernationDevice: + #RESUME=UUID=6932e499-f0ad-4456-b93c-2b7f9bf763dc + RESUME=UUID=ce49bc01-a59b-4abf-9110-87bc71689769 + InstallationDate: Installed on 2009-11-01 (4055 days ago) + InstallationMedia: Kubuntu 9.10 "Karmic Koala" - Release amd64 (20091027) + MachineType: LENOVO 81YK + NonfreeKernelModules: wl + Package: xorg 1:7.7+19ubuntu15 + PackageArchitecture: amd64 + ProcFB: 0 i915drmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.8.0-31-generic root=/dev/mapper/vg_c540scadaw-root64 ro rootflags=commit=3600 transparent_hugepage=always init=/lib/systemd/systemd + ProcVersionSignature: Ubuntu 5.8.0-31.33-generic 5.8.17 + RelatedPackageVersions: + linux-restricted-modules-5.8.0-31-generic N/A + linux-backports-modules-5.8.0-31-generic N/A + linux-firmware 1.192 + Tags: hirsute ubuntu single-occurrence reproducible has-workaround + Uname: Linux 5.8.0-31-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm admin cdrom dialout dip disk kvm libvirt lpadmin netdev plugdev sambashare src + _MarkForUpload: True + dmi.bios.date: 07/06/2020 + dmi.bios.release: 1.45 + dmi.bios.vendor: LENOVO + dmi.bios.version: DPCN45WW + dmi.board.asset.tag: NO Asset Tag + dmi.board.name: LNVNB161216 + dmi.board.vendor: LENOVO + dmi.board.version: NO DPK + dmi.chassis.asset.tag: NO Asset Tag + dmi.chassis.type: 10 + dmi.chassis.vendor: LENOVO + dmi.chassis.version: IdeaPad 5 15IIL05 + dmi.ec.firmware.release: 1.45 + dmi.modalias: dmi:bvnLENOVO:bvrDPCN45WW:bd07/06/2020:br1.45:efr1.45:svnLENOVO:pn81YK:pvrIdeaPad515IIL05:rvnLENOVO:rnLNVNB161216:rvrNODPK:cvnLENOVO:ct10:cvrIdeaPad515IIL05: + dmi.product.family: IdeaPad 5 15IIL05 + dmi.product.name: 81YK + dmi.product.sku: LENOVO_MT_81YK_BU_idea_FM_IdeaPad 5 15IIL05 + dmi.product.version: IdeaPad 5 15IIL05 + dmi.sys.vendor: LENOVO + version.compiz: compiz N/A + version.libdrm2: libdrm2 2.4.103-2 + version.libgl1-mesa-dri: libgl1-mesa-dri 20.2.4-1 + version.libgl1-mesa-glx: libgl1-mesa-glx N/A + version.xserver-xorg-core: xserver-xorg-core 2:1.20.9-2ubuntu1.1 + version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.10.6-2 + 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 ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1907308/+attachment/5442088/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1907308 Title: screen brightness up/down keys not working in LENOVO IdeaPad 5 15IIL05 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1907308/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
