Bug ID: 98733
Summary: Touchpad gets a stuck button if used while TrackPoint
button is down
Product: Wayland
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: libinput
Assignee: [email protected]

I have a ThinkPad Yoga 14 with both a touchpad and physical buttons for the
TrackPoint, and I like to use them at the same time, but recently I’ve found
that this often causes a button to get temporarily stuck in the down state.
Here’s what this looks like in libinput-debug-events (event8 = physical
buttons, event9 = touchpad):
(I rest my finger on the touchpad)
event9 POINTER_MOTION +1.88s 0.25/ 0.00
event9 POINTER_MOTION +1.89s 0.12/ 0.00
(I depress a physical button)
event8 POINTER_BUTTON +2.00s BTN_LEFT (272) pressed, seat count: 1
event9 POINTER_BUTTON +2.00s BTN_LEFT (272) pressed, seat count: 2
(I pick up my finger from the touchpad; no output)
(I release the physical button)
event8 POINTER_BUTTON +2.87s BTN_LEFT (272) released, seat count: 1
(At this point my fingers are not touching anything.)
(I rest my finger on the touchpad, which now finally sends its button release.)
event9 POINTER_BUTTON +5.69s BTN_LEFT (272) released, seat count: 0
event9 POINTER_MOTION +5.76s 0.20/ -0.61
event9 POINTER_MOTION +5.77s 1.00/ -1.53
I’m using xserver-xorg-input-libinput 0.19.0-1 and libinput10 1.4.3-0ubuntu1 on
Ubuntu 17.04.
