I had the same problem (keyboard not working, touchpad working) for a 6.x kernel. The workaround from Johannes and Bernd worked for me, though I only used "quiet splash i8042.nomux=1" and did not test the additional "i8042.reset".
System: Fujitsu Lifebook 7U15A1, Ubuntu 22.04.3 LTS, Kernel 6.2.0-36-generic x86_64 Btw: "cat /sys/class/dmi/id/chassis_type" still shows "10" and the Fujitsu 7U15A1 is not a tablet nor a convertible. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2033271 Title: Fujitsu keyboard not working after updates Status in linux package in Ubuntu: Confirmed Bug description: Ubuntu 22.04.3 LTS Fujitsu Lifebook E5410 Expected to happen is that the keyboard is working as previous before the updates. What instead happens is, that the keyboard is dead and does not work. Attaching an external USB-keyboard works. The keyboard works before boot in the BIOS context, so it is not hardware related. -- There is another user reporting the same issue for a E5510 on ask Ubuntu. https://askubuntu.com/questions/1483381/ubuntu-22-04-fujitsu- lifebook-e5510-keyboard-not-working-after-update-kernel ProblemType: Bug DistroRelease: Ubuntu 22.04 Package: linux-image-6.2.0-26-generic 6.2.0-26.26~22.04.1 ProcVersionSignature: Ubuntu 6.2.0-26.26~22.04.1-generic 6.2.13 Uname: Linux 6.2.0-26-generic x86_64 ApportVersion: 2.20.11-0ubuntu82.5 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Mon Aug 28 12:01:29 2023 InstallationDate: Installed on 2022-04-21 (493 days ago) InstallationMedia: Ubuntu 22.04 LTS "Jammy Jellyfish" - Release amd64 (20220419) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=de_DE.UTF-8 SHELL=/bin/bash SourcePackage: linux-signed-hwe-6.2 UpgradeStatus: No upgrade log present (probably fresh install) --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu82.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: cysec 1698 F.... pulseaudio CRDA: N/A CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 22.04 InstallationDate: Installed on 2022-04-21 (497 days ago) InstallationMedia: Ubuntu 22.04 LTS "Jammy Jellyfish" - Release amd64 (20220419) MachineType: FUJITSU CLIENT COMPUTING LIMITED LIFEBOOK E5410 Package: linux (not installed) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=de_DE.UTF-8 SHELL=/bin/bash ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-6.2.0-31-generic root=/dev/mapper/vgubuntu-root ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 6.2.0-31.31~22.04.1-generic 6.2.15 RelatedPackageVersions: linux-restricted-modules-6.2.0-31-generic N/A linux-backports-modules-6.2.0-31-generic N/A linux-firmware 20220329.git681281e4-0ubuntu3.18 Tags: wayland-session jammy Uname: Linux 6.2.0-31-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin lxd plugdev sambashare sudo wireshark _MarkForUpload: True dmi.bios.date: 06/30/2023 dmi.bios.release: 2.30 dmi.bios.vendor: FUJITSU CLIENT COMPUTING LIMITED dmi.bios.version: Version 2.30 dmi.board.name: FJNB2D6 dmi.board.vendor: FUJITSU CLIENT COMPUTING LIMITED dmi.board.version: A2 dmi.chassis.type: 10 dmi.chassis.vendor: FUJITSU CLIENT COMPUTING LIMITED dmi.chassis.version: LIFEBOOK E5410 dmi.modalias: dmi:bvnFUJITSUCLIENTCOMPUTINGLIMITED:bvrVersion2.30:bd06/30/2023:br2.30:svnFUJITSUCLIENTCOMPUTINGLIMITED:pnLIFEBOOKE5410:pvr10601736746:rvnFUJITSUCLIENTCOMPUTINGLIMITED:rnFJNB2D6:rvrA2:cvnFUJITSUCLIENTCOMPUTINGLIMITED:ct10:cvrLIFEBOOKE5410:skuSK01: dmi.product.family: LIFEBOOK-FTS dmi.product.name: LIFEBOOK E5410 dmi.product.sku: SK01 dmi.product.version: 10601736746 dmi.sys.vendor: FUJITSU CLIENT COMPUTING LIMITED To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2033271/+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
