Sorry for the delay. The input issues first crop up in 4.13-rc1. I also noticed that the latest 4.16-rc2 doesn't seem to be affected by the issue.

On first boot, the touchpad and keyboard will work sporadically with random keys occasionally being registered as being pressed. After some time, both the touchpad and keyboard completely stop functioning. We've replicated the issue on other 11e laptops to ensure it wasn't a hardware problem. Touchpad and keyboard both work perfectly on Ubuntu 16.04.3 dmesg is showing a bunch of the following: psmouse serio1: Touchpad at isa0060/serio1/input0 lost synchronization, throwing 4 bytes away. psmouse serio1: resync failed, issuing reconnect request psmouse serio1: synaptics: unable to initialize device What we expect to happen: Touchpad and Keyboard will allow user input What happened instead: Touchpad and Keyboard register random input or don't function at all. --- ApportVersion: 2.20.7-0ubuntu3.6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: tech 970 F.... pulseaudio CurrentDesktop: XFCE DistroRelease: Ubuntu 17.10 InstallationDate: Installed on 2017-12-12 (7 days ago) InstallationMedia: Xubuntu 17.10 "Artful Aardvark" - Release amd64 (20171017.1) MachineType: LENOVO 20GBS00S00 Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.13.0-19-generic root=UUID=8b4328ce-7dad-4e55-8229-df928776303b ro quiet splash acpi_osi=Linux acpi_lightback=vendor vt.handoff=7 ProcVersionSignature: Ubuntu 4.13.0-19.22-generic 4.13.13 RelatedPackageVersions: linux-restricted-modules-4.13.0-19-generic N/A linux-backports-modules-4.13.0-19-generic N/A linux-firmware 1.169.1 Tags: artful Uname: Linux 4.13.0-19-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm audio cdrom dialout dip fax floppy lpadmin plugdev sambashare scanner sudo tape video _MarkForUpload: True dmi.bios.date: 03/01/2017 dmi.bios.vendor: LENOVO dmi.bios.version: R0AET33W (1.16) dmi.board.asset.tag: Not Available dmi.board.name: Intel powered classmate PC dmi.board.vendor: LENOVO dmi.board.version: SDK0K13467 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrR0AET33W(1.16):bd03/01/2017:svnLENOVO:pn20GBS00S00:pvrThinkPad11e3rdGen:rvnLENOVO:rnIntelpoweredclassmatePC:rvrSDK0K13467WIN:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.family: ThinkPad 11e 3rd Gen dmi.product.name: 20GBS00S00 dmi.product.version: ThinkPad 11e 3rd Gen dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1739102/+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
