Just downloaded libinput 1.8.4 from artful-updates, compiled the debian package via debuild and installed it on my bionic system. Rebooted the system and I'm _fairly certain_ the laggy cursor problem gone away.
At this point I might be able to bisect the problem with different versions of libinput, as well as try the new release. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
