I can reproduce this both with synaptics and libinput and I've learned now that the evtest results are kernel events, so libinput isn't involved at that point at all. Hence, I have moved this to the kernel[1] and will close this bug here. [1] https://bugzilla.kernel.org/show_bug.cgi?id=106601 |

Created attachment 119162 [details] evtest The synaptics touchpad on my X1 Carbon (3rd gen) is occasionally jumpy when moving the pointer with one finger, but it only seems to happen when moving really slow (like when adjusting a volume slider). I'll attach an evtest log and looking at it, it seems that when the jump happens, only pressure events are reported for a while and no motion events (see line 1658ff.). I'm not familiar with libinput in any way, that's all I can see. It may not even be a libinput issue, but any input on how to proceed or where to take this would be appreciated. P.S.: This is somewhat related to #91615, but the log file there doesn't seem to show the same pattern, so it may not be the same -- plus it's supposed to be fixed.
