DESCRIPTION
Hi! Very new to bug reporting so please have mercy. I was troubleshooting with
Claude about why the drawing tablet settings were wrongly reporting that my
Intuos Pro Medium (PTK670) was being recognized as being managed by a third
party driver despite the fact that it should be handled natively. Here is
Claude's account:
System Settings' Tablet page shows the message "This device is managed by a
user-space driver that you installed. Use that driver to configure the
tablet instead of using the settings here, unless specifically instructed
otherwise" for a Wacom Intuos Pro M (2025, "ProM2") connected via Bluetooth,
even though no user-space tablet driver (e.g. OpenTabletDriver) is installed
on the system.
The device is fully recognized at every layer below Plasma:
- The kernel/libinput correctly enumerate both the Pen and Pad nodes with
full tablet and tablet-pad capabilities (correct size, 10 buttons, 2
dials, 2 mode groups).
- `libwacom-list-local-devices` returns a complete, detailed entry for the
device (bus: bluetooth, vid: 0x056a, pid: 0x03f8, name: "Wacom Intuos Pro
M"), including full pen/pad node mapping and its full stylus database
(Pro Pen 3, Pro Pen 3E, Art Pen 2, plus legacy pen IDs).
Despite libwacom having a complete, non-generic profile for this exact
device, the Plasma Tablet KCM does not recognize it and instead shows the
user-space-driver message, leaving the tablet's buttons, dials, and pen
settings unconfigurable through System Settings.
Note: the same physical tablet's wired USB connection uses a different
product ID (056a:03f7) than the Bluetooth connection (056a:03f8). It's
possible the KCM's device-matching logic does not correctly handle this
Bluetooth-specific PID even though libwacom's database does.
STEPS TO REPRODUCE
1. Connect a Wacom Intuos Pro M (2025 revision) to the system over
Bluetooth (not USB).
2. Confirm no user-space tablet driver (OpenTabletDriver, DIGImend, etc.)
is installed.
3. Open System Settings → Input Devices → Tablet.
OBSERVED RESULT
The Tablet page displays: "This device is managed by a user-space driver
that you installed. Use that driver to configure the tablet instead of
using the settings here, unless specifically instructed otherwise." No
pen, pad, button, or dial settings are available to configure, even though
`libinput list-devices` and `libwacom-list-local-devices` both show the
tablet is fully and correctly recognized with a complete libwacom device
profile.
EXPECTED RESULT
EXPECTED RESULT
System Settings should recognize the Bluetooth-connected Wacom Intuos Pro M
as a standard kernel/libwacom-managed tablet (as it already does for the
same tablet over USB) and expose the normal Tablet configuration page —
pen mapping, pad button/dial assignment, screen area, etc. — instead of
showing the user-space-driver message.
