Not 100% certain if this is the right bug for this, but I'm seeing similar behaviour for trackpoints and touchpads on the Thinkpad X230 and Thinkpad X131e for at least Ubuntu (standard) and Ubuntu MATE.
Laggy is a vague term, but for me specifically I'm seeing that the cursor moves in a constant motion until I stop. Then after a small moment, it "jumps" a short/random distance in the direction of motion before I stopped. This is very very pronounced when using the trackpoint. I see some similar reports on various corners on the internet that is similar to what I'm seeing: - https://www.reddit.com/r/Ubuntu/comments/8fiiik/touchpad_not_working_properly_on_ubuntu_1804/ - OP reports "The cursor moves slowly but suddenly very fast." - https://askubuntu.com/questions/1030847/ubuntu-18-04-lts-intel-graphics-issue - https://askubuntu.com/questions/1031447/why-is-my-ubuntu-18-04-lagging-and-there-is-also-difficulty-using-mouse-it-is -- 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
