I've also got an L322X - and am experiencing this same issue, touchpad seems to lock up after some time, and is also impossible to click and drag with.
I've just installed a fresh Bionic system onto my machine, and have the latest updates. That did not seem to help. I installed "xserver-xorg-input-synaptics" and now the touchpad seems to work fine when I use the Xorg session. I haven't tried the Wayland session. -- 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 firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
