Hi Christian, I've just checked and toggling "Natural Scrolling" does work on touchpads for other people such as myself. You might want to check if the "Natural Scrolling" option is listed under "Touchpad" or under "Mouse". Make sure you set the one under "Touchpad".
If that doesn't fix it then the issue is probably that Ubuntu is mistaking your touchpad for a mouse. So the relevant configuration options you need for "Touchpad" may be missing, or may be misinterpreted. Please start by providing a screenshot of your Mouse & Touchpad settings. And also you might want to try downgrading your Ubuntu kernel to 4.9 or earlier (so it's more like Debian 9): kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D If Ubuntu is mistaking your touchpad for a mouse then that might fix it. ** Changed in: libinput (Ubuntu) Status: Confirmed => Incomplete -- 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/1725416 Title: Elantech touch pad device not detected/working properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1725416/+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
