Description Timm Bäder 2015-11-29 12:52:53 UTC

I have a Thinkpad T410s, which has a touchscreen and a touchpad.
Whenever I press the touchscreen, I get journal messages like:
libinput error: libinput bug: Event for missing capability CAP_POINTER on device "N-Trig MultiTouch"

This is reproducible and happens with every touch on the touchscreen. I get other messages, however, and I'm not sure how to reliable trigger them, like:

  (1) libinput error: libinput bug: Unable to find topmost touch
  (2) libinput error: libinput bug: invalid tap event when fingers are up

(2) seems to *sometimes* happen when I press the touchpad with 2 fingers at once, then lift one of the fingers, and (1) happens after that when I use only one finger (but also just sometimes, I'm not sure if that's the exact way to reproduce it).

libinput-list-devices prints:

(I removed a few things I think are unimportant like the power button or the integrated camera, just to make the report shorter).

I have libinput 1.1 installed and wayland 1.9 (which I can't select in bz for some reason)

This is all using gnome-shell 3.18.3 which I also have in jhbuild, so if you need more information or if I should test a patch, that's fine.

Comment 1 Peter Hutterer 2015-12-01 07:11:49 UTC

try to record a sequence with evemu-record, that way I can replay it here and figure out what's going on. Should be easy to identify then.

Here's the log from the missing CAP_POINTER output (selected device was the N-Trig Multitouch one):
