if you just run libinput-debug-events does the output look sane?

Still seeing the same behavior in that having the tablet plugged in seems to
affect mouse scrolling behavior in gimp and inkscape both. Otherwise working
fine (and the buttons now work on libinput where they didn't before).

I've done the reboot, it's still there as checked by udevadm info /sys..., but
evemu-record only ever shows BTN_TOOL_PEN once =(

once it's picked up correctly, you need to restart X or the compositor. Or
reboot, that's easiest. Then check it's still there with udevadm info /sys/...
and it should work now.

the different ids are expected, one is kernel event node number, the other one
is X device ID, they're two different things.

Ah, because... I'm stupid I guess.

Anyway I'm now using that, udevadm test shows the property was picked up, but
behaviour seems unchanged in that my evemu-record only shows BTN_TOOL_PEN once.
Would the evemu-record help or is there some other info which is needed?

Something which may or may not be interesting, under evemu-record the id for
the Pentablet Pen is 17

this should be just 1, not "reserved", otherwise it won't get picked up. a sudo
udevadm test /sys/class/input/eventX should tell you whether the property is
picked up correctly by udev. and for the above to work, you need to uppercase
the hex, so it's b003v256Cp006E*. Those are the ones I can immediately spot,
but why didn't you just use the example that's already in there (and matches by
name)?

Okay gave that a try. Not sure if my hwdb is a) correct and b) taking effect,
but no difference in behavior that I can see. This is what I put in
/etc/udev/hwdb.d/70-HuionDWH69.hwdb

give this one a try please:
https://github.com/whot/libinput/tree/wip/huion-dwh69-fdo97771

Note that you need to set the hwdb entry (see the last commit) so that the udev
property shows up on your device, otherwise it won't apply.

evemu-record output for Pen device - immediately after boot

Looks like you're right. It shows BTN_TOOL_PEN in this situation.

Muslim: Weston doesn't have tablet support yet, so that's expected. GNOME
should have it in the latest version, but unless you're on F25, don't expect it
to work. IIRC the Huion tablets re-use product ids, so let's file a separate
bug for yours because this bug is about one that doesn't work in libinput at
all. But if you say it works under X then it's highly likely that it works fine
anyway (unless you have the wacom driver hooked up to it). But either way,
separate bug please, thanks.

@ Peter Hutterer

Thanks for the informations.

Should I open a new bug report ? Since it works for me under Xorg, but not
under Wayland/Xwayland.

Finally, I am able to "see" the tablet through libinput-list-devices and
libinput-debug-events, but unable to use it under Gnome3/Wayland nor
Weston/Wayland.

no worries, sorry about not being clear

> Should I be using the patch from commit 19 for this test?

yes please, given that it's needed anyway

> Should I be rebooting with the device plugged in or plug it in after boot?

shouldn't matter, but safer to plug it in after boot (less chance of accidental
events)

> If the latter, I guess I should start evemu-record before plugging it in?

that won't work because evemu-record needs the device node which won't exist
until it's plugged in.

xinput on Wayland runs through Xwayland. And Xwayland doesn't see all input
devices because it only sees what's on the wayland protocol and that works
differently. So running xinput under wayland is almost always pointless.

ngoonee, please do the following: reboot the machine without touching the
tablet. then start evemu-record. *now* use the tablet for a single sequence and
attach the output. I'm wondering whether the BTN_TOOL_PEN is never sent or just
sent once on the very first event. That's why it's important that the tablet
does not generate any events until you have evemu running

Hi,

Same problem on Debian.

Under X sessions, the Huion tablet, identified like "256c:006e", works very
well (not yet tried "shortcuts").

'xinput list' command returns this:

⎡ Virtual core pointer  id=2[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointerid=4[slave  pointer  (2)]
⎜   ↳ USB Optical Mouse id=11   [slave  pointer  (2)]
⎜   ↳ PenTablet  Penid=12   [slave  pointer  (2)]
⎣ Virtual core keyboard id=3[master keyboard (2)]
↳ Virtual core XTEST keyboard   id=5[slave  keyboard (3)]
↳ Power Button  id=6[slave  keyboard (3)]
↳ Video Bus id=7[slave  keyboard (3)]
↳ Power Button  id=8[slave  keyboard (3)]
↳ Logitech Logitech USB Keyboardid=9[slave  keyboard (3)]
↳ Logitech Logitech USB Keyboardid=10   [slave  keyboard (3)]

While under Wayland, xinput returns this:

⎡ Virtual core pointer  id=2[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointerid=4[slave  pointer  (2)]
⎜   ↳ xwayland-pointer:13   id=6[slave  pointer  (2)]
⎜   ↳ xwayland-relative-pointer:13  id=7[slave  pointer  (2)]
⎣ Virtual core keyboard id=3[master keyboard (2)]
↳ Virtual core XTEST keyboard   id=5[slave  keyboard (3)]
↳ xwayland-keyboard:13  id=8[slave  keyboard (3)]

Is it normal that, even the Mouse and the Keybord are not identified correctly?

Thanks
