So : I updated this morning my professional HP 450 G3 with SynPS/2 Synaptics touchpad and I experience exactly the same bug. Especially annoying (running both Dell & HP) when scrolling a PDF (two fingers) in Evince.
It's maybe not hardware-related ? ** Summary changed: - [Bionic] 1.9.4-2ubuntu1 makes touchpad jumpy on Dell Precision 7510 + [Bionic] 1.9.4-2ubuntu1 makes touchpad jumpy on Dell Precision 7510 and HP 450 G3 -- 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 on Dell Precision 7510 and HP 450 G3 To manage notifications about this bug go to: https://bugs.launchpad.net/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
