Please try VT switching to VT4 (Ctrl+Alt+F4), log in and retest with 'evtest'. If you continue to get no results then that's a kernel bug. Because Wayland and libinput are not part of the equation when you're testing the kernel directly.
P.S. Also check if your laptop keyboard has a function key for disabling/enabling the touchpad. It might simply be disabled in hardware (for reasons unknown). ** Package changed: libinput (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Status: Fix Released => Incomplete -- 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/1726934 Title: Elantech touchpad unresponsive in Ubuntu 17.10 Status in linux package in Ubuntu: Incomplete Bug description: I have upgraded to Ubuntu 17.10 on my Asus Vivobook X505BA laptop and with the upgrade to Wayland full-time, all of the elantech issues from a few years back are coming back with a vengeance. Upon upgrade, my trackpad is no longer functional and I am forced to use an external mouse. I don't have an extra mouse that I can just drag around with the laptop, nor do I wish to purchase one to use when I have a trackpad on the laptop itself. Dmesg doesn't show anything about the driver failing to load and syslog shows nothing either. I know this is a common issue with this kind of trackpad but I hope to see a fix soon so I can go back to using Ubuntu normally To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1726934/+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
