Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.14 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

It does not react to single finger movement or tapping, nor to two finger scroll, nor to pressing down the clickpad left or right. The laptop has a detachable screen for use as a tablet. After detaching the screen and reattaching the screen the touchpad works again as expected. I've tried it now a few times and I can reliably reproduce the touchpad problem as follows: - close the lid, - wait for the led to indicated sleeping. - Open the lid. - Hit enter (otherwise the screen stays dark). - Enter password to unlock using the keyboard. - Try keyboard and touchpad to see whether they work. - It they don't work - Pull the screen off of the keyboard base with the integrated touchpad. - Reconnect - Try keyboard and touchpad again .... A few attempts below with approximate times. Should be visible in the syslog for Nov 18 NB: In one of these tests the keyboard didn't work after disconnect/reconnect. But that is not a persistent problem. I don't remember having seen that before, nor was I able to reproduce it a second time. -------------- close lid 10:14:55 open -> keyboard works -> touchpad doesnt work disconnect 10:25:09 reconnect -> keyboard doesnt work -> touchpad doesnt work disconnect reconnect -> keyboard works -> touchpad works -------------- close lid 10:39:20 open -> keyboard works -> touchpad doesn't work disconnect 10:41:11 reconnect -> keyboard works -> touchpad works -------------- close lid 10:47:50 open -> keyboard works -> touchpad doesnt work disconnect 10:48:37 reconnect -> keyboard works -> touchpad works ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: linux-image-4.13.0-16-generic 4.13.0-16.19 [modified: boot/vmlinuz-4.13.0-16-generic] ProcVersionSignature: Ubuntu 4.13.0-16.19-generic 4.13.4 Uname: Linux 4.13.0-16-generic x86_64 ApportVersion: 2.20.7-0ubuntu3.4 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: peter 1195 F.... pulseaudio CurrentDesktop: ubuntu:GNOME Date: Sat Nov 18 10:50:00 2017 HibernationDevice: RESUME=UUID=ccc9dd4a-8423-499f-8e57-022be496cfa6 InstallationDate: Installed on 2017-11-05 (12 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Release amd64 (20171018) MachineType: HP HP Pavilion x2 Detachable ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.13.0-16-generic.efi.signed root=UUID=c516cd88-8b77-434a-813a-799e0380a4eb ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-4.13.0-16-generic N/A linux-backports-modules-4.13.0-16-generic N/A linux-firmware 1.169 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 03/14/2016 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: F.13 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: 8181 dmi.board.vendor: HP dmi.board.version: 42.25 dmi.chassis.type: 10 dmi.chassis.vendor: HP dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrF.13:bd03/14/2016:svnHP:pnHPPavilionx2Detachable:pvr:rvnHP:rn8181:rvr42.25:cvnHP:ct10:cvrChassisVersion: dmi.product.family: 103C_5335KV G=N L=CON B=HP S=SPT dmi.product.name: HP Pavilion x2 Detachable dmi.sys.vendor: HP To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1733060/+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
