Title: Acer Aspire E15 keyboard and trackpad non functional after update to vmlinuz-5.4.0-47-generic Status in linux package in Ubuntu: Confirmed Bug description: Have an Acer Aspire E15 running Kubuntu 20.04 Expect: Trackpad and keyboard to work after boot to WM login. What Happens: Trackpad/keyboard unresponsive after WM starts. Recently ( within last month) an update has caused the trackpad and keyboard to stop being detected after the WM starts and autologin is complete. Ive reinstalled which puts me at vmlinuz-5.4.0-26-generic, and the trackpad/keyboard worked normally. After updating to vmlinuz-5.4.0-47-generic and rebooting problem reoccurs. Booting to console: keyboard works normally. Booting via Ubuntu advanced options to 5.4.0-26: Keyboard/trackpad works normally. Some Fn buttons work after login, but only ones monitored by firmware (E.g. screen brightness works, volume control doesn't) neil@neil-Aspire-E5-511:~$ lsb_release -rd Description: Ubuntu 20.04.1 LTS Release: 20.04 ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-26-generic 5.4.0-26.30 ProcVersionSignature: Ubuntu 5.4.0-26.30-generic 5.4.30 Uname: Linux 5.4.0-26-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: neil 943 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: KDE Date: Fri Sep 11 19:20:04 2020 InstallationDate: Installed on 2020-09-10 (1 days ago) InstallationMedia: Kubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) MachineType: Acer Aspire E5-511 ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/@/boot/vmlinuz-5.4.0-26-generic root=UUID=7c62eb69-2b7c-4aea-a384-1460d6533ecd ro rootflags=subvol=@ quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-5.4.0-26-generic N/A linux-backports-modules-5.4.0-26-generic N/A linux-firmware 1.187.3 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 09/09/2015 dmi.bios.vendor: Acer dmi.bios.version: V1.10 dmi.board.name: Aspire E5-511 dmi.board.vendor: Acer dmi.board.version: V1.10 dmi.chassis.type: 10 dmi.chassis.vendor: Acer dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnAcer:bvrV1.10:bd09/09/2015:svnAcer:pnAspireE5-511:pvrV1.10:rvnAcer:rnAspireE5-511:rvrV1.10:cvnAcer:ct10:cvrChassisVersion: dmi.product.family: Bay Trail-M System dmi.product.name: Aspire E5-511 dmi.product.sku: Aspire E5-511_0905_V1.10 dmi.product.version: V1.10 dmi.sys.vendor: Acer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1895342/+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
