Description ell1e 2016-08-01 14:21:39 UTC

Description of problem:
With wayland, the pen of Thinkpad Yoga 260 doesn't work. It's simply as if it isn't recognized at all, no clicks or any sort of events seem to result in anything happening ever. Under X11, it works fine.

Version-Release number of selected component (if applicable):
Wayland compositor used is GNOME Shell 3.20.3

How reproducible:
100%

Steps to Reproduce:
1. Start GNOME Wayland session instead of X11
2. Try to use pen to click things or in applicaitons like GIMP or xournal

Actual results:
doesn't work

Expected results:
works

I have the same issue on my 260. The pen didn't work for me in Xournal, but it did work in general (for moving windows around for example). Maybe this is a problem with Xournal?

Comment 2 Denis Auroux 2016-11-30 16:06:15 UTC

Wacom pen support seems to be broken on wayland, and in general the X input device emulation on wayland is not good, for GTK2 applications at least. As noted by the original poster, GIMP is affected as well -- it's not specifically a xournal or gimp issue.  

There is no current solution to this problem as far as I know, apart from asking for wacom support and more generally X input device emulation support on wayland in a way that doesn't break GTK2 applications. 

In principle the libinput component of wayland is supposed to know how to handle wacom tablets, but in practice that knowledge does not seem to reach X-based applications. It could be that GTK3 over Wayland backend can get tablet input better than GTK over X11 backend with X11-over-Wayland, but since xournal uses GTK2 that doesn't help us.

Under Fedora 25 with default GNOME Wayland, it has gotten slightly better:

The following works:
- Moving windows around with the titlebars
- Everything in gedit (clicking buttons and selecting stuff)

The following doesn't work at all:
- Clicking or interacting in any way inside firefox
- Same for gajim
- Same for xournal
- Same for GIMP 2.8

... sadly this means the pen doesn't work for more than half the regular applications I need, and specifically those where you would really WANT to use it (xournal, GIMP) don't work.

Given Wayland is the default now, maybe some time should be spent to fixing this?

I just filed an upstream bug report here: https://bugs.freedesktop.org/show_bug.cgi?id=99411
