Hi Francois, The patch in 1.9.4-2ubuntu1 is the same as what's coming soon in libinput release 1.10. So a fix for your specific touchpad should be done upstream. Simply reverting the patch won't help you after we update to libinput 1.10, and besides most laptops seem to need that patch.
Please report the issue to the libinput developers here: https://bugs.freedesktop.org/enter_bug.cgi?product=wayland&component=libinput And when done let us know the ID of your newly created bug. ** Changed in: libinput (Ubuntu) Status: New => 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/1745816 Title: [Bionic] 1.9.4-2ubuntu1 makes touchpad jumpy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1745816/+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
