            Bug ID: 98265
           Summary: Wacom tablet not found by Gnome 3.22
           Product: Wayland
           Version: 1.5.0
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: camalot at picnicpark.org

I upgraded to Gnome 3.22 on Archlinux yesterday and my Wacom Intuos PTH-451
tablet is no longer detected and configurable through the Gnome Settings Wacom
Tablet settings panel.  In addition, while the touchpad controls the regular
mouse pointer and seems to work fine, the pen controls a separate pointer that
seems to react to the windows on the screen, changing pointer shape based on
whether it is on the edge of a window to indicate the window can be resized,
etc. but clicking any of the buttons and touching the tip to the tablet
generally doesn't seem to work to click on GUI controls.  Though, on some (but
not all) windows, it does allow dragging the window.  It also works to
left-click on gnome-shell controls such as the Activities overview button on
the left side of the bar across the top of the screen.

I'm using libinput and xf86-input-libinput, currently without xf86-input-wacom,
though I tried using xf86-input-wacom and seem to get the same behavior.

I'm not sure where to start with debugging this.  It seems like the fact that
the tablet is not recognized and configurable in the Settings panel is a good
place to start and that seems likey to the be related to the way the input
system works, so I'm starting by filing a bug here.

Here are the libinput package versions I'm currently running:

[amidon at kea-tablet ~]$ pacman -Ss libinput
extra/libinput 1.5.0-1 [installed]
    Input device management and event handling library
extra/xf86-input-libinput 0.20.0-1 (xorg-drivers xorg) [installed]
    Generic input driver for the X.Org server based on libinput

I've attached an evmu-record of some events from the pen device, though I'm not
sure that will be helpful in this case.  I've also attached the output of
libinput-list-devices.

Suggestions on where to go from here would be greatly appreciated.
