I have upgraded to Bionic recently and my touchpad immediately became close to unusable. The sensitivity was WAY too high so the cursor could only be moved with extremely low pressure. Anything beyond seemed to be considered a palm pressure or something. In addition, the touchpad buttons had become unusable wrt. click/hold+swipe to drag stuff around. The problems occurred both in Wayland and XOrg.
I did a clean Bionic reinstall which did not help. Then I reinstalled Artful and the problems where resolved. After a subsequent upgrade to Bionic the problem reappeared. -- 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/1746740 Title: XPS13 L322X Bionic (daily dev) touchpad laggy To manage notifications about this bug go to: https://bugs.launchpad.net/libinput/+bug/1746740/+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
