Description Jacek 2017-11-19 19:25:57 UTC

I am currently running Fedora 27 with fresh packages (Gnome 3.26.2, libinput 1.9.0), but I have noticed the problem a few months ago on Arch (Gnome 3.24, libinput 1.7 and 1.8). I have a 1st gen Lenovo Thinkpad X1 Yoga (touchscreen + wacom pen).

The problem is with the touchscreen. I can use touch screen just fine for scrolling and clicking. The problem starts when I try a long press for a right click. The right click works, but the touch screen starts behaving as the finger stays in that place. As a result the touchscreen is no longer usable until I logout and login again. 

I will be happy to generate and provide logs (I would need instructions how to do it though).

Thanks!

I forgot to add I use Wayland. The issue does not occur on Xorg.

unlikely to be a libinput bug then because libinput doesn't know what display server is running and always provides the same events. To verify run sudo libinput debug-events and reproduce the issue. If the event log on the libinput side looks sane (i.e. you see release events as expected) then it's not a libinput bug.
