I don't know if these issues are caused by the above errors or > are a separate issue. Just to confirm: I noticed "jumpiness during fine pointing motions" as well since switching to 4.11-rc. @benjamin: Just wondering: Could that have something to do with the ps2->rmi handover? I noticed that patches to improve things in this area are still circulating, which lead me to wonder if that might have anything to do with this. But it's just a wild guess. > The affected machine is an XPS 13 9343 running Fedora 25 with 4.11-rc1 > and libinput 1.6.3-3.fc25 (latest in F25). Same setup here. In case it matters: I'm running Gnome-Shell in Wayland mode. Ciao, Thorsten P.S.: I fixed the model number in above quotes from Cameron to avoid confusion (he has a 9343, and not a 9443, as initially stated; see a different mail in this thread for details)
