All right, I took your advice and tested several older kernels: linux-headers-4.10.0-19_4.10.0-19.21_all.deb linux-headers-4.10.0-19-generic_4.10.0-19.21_amd64.deb linux-headers-4.10.0-26_4.10.0-26.30_all.deb linux-headers-4.10.0-26-generic_4.10.0-26.30_amd64.deb linux-headers-4.11.0-13_4.11.0-13.19_all.deb linux-headers-4.11.0-13-generic_4.11.0-13.19_amd64.deb linux-headers-4.12.0-13_4.12.0-13.14_all.deb linux-headers-4.12.0-13-generic_4.12.0-13.14_amd64.deb linux-image-4.10.0-19-generic_4.10.0-19.21_amd64.deb linux-image-4.10.0-26-generic_4.10.0-26.30_amd64.deb linux-image-4.11.0-13-generic_4.11.0-13.19_amd64.deb linux-image-4.12.0-13-generic_4.12.0-13.14_amd64.deb
I installed all these deb files, and booted with them, and the bug is STILL present. It seems like I can't reproduce the working kernel of the artful livecd. Any idea about how should I proceed? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libinput in Ubuntu. https://bugs.launchpad.net/bugs/1816947 Title: [Dell XPS L321X] Touchpad not working after last apt-get upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1816947/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
