I added the following line to my /etc/default/grub GRUB_CMDLINE_LINUX="psmouse.elantech_smbus=0" then ran "sudo update-grub" in the usual way and track pad and buttons work now. This worked for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1803600 Title: Elantech - Touchpad not working after upgrading to 18.10 from 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1803600/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
