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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1907308/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
