Chapter 20. Tablets
To manage Wacom tablets connected to your system, use the following tools:
Wacom Tabletsettings panel in the GNOME environment
The Wacom Tablet settings panel for a tablet
The Wacom Tablet settings panel for a grip pen
Both these tools, as well as the
libinput stack, use the
libwacom tablet client library, which stores the data about Wacom tablets.
If you want to add support for a new tablet into the
libwacom library, you must ensure that a definition file for this new tablet exists.
20.1. Preparing a tablet definition file
libwacom tablet client library needs a definition file for the tablet that you want to add.
To ensure that the tablet definition file exists, follow this procedure.
List all local devices recognized by
Make sure that your device is recognized in the output.
If your device is not listed, the device is missing from the
libwacomdatabase. However, the device might still be visible as an event device in the kernel under
/proc/bus/input/devices, and if you use the X.Org display server, in the X11 session on the
Install the package that provides tablet definition files:
# yum install libwacom-data
The package installs tablet definitions in the
Check whether the definition file is available in the
To use the screen mapping correctly, support for your tablet must be included in the
libwacomdatabase and in the
A common indicator that a device is not supported by
libwacomis that it works normally in a GNOME session, but the device is not correctly mapped to the screen.
If the definition file for your device is not available in
/usr/share/libwacom/, you have these options:
- The required definition file may already be available in the linuxwacom/libwacom upstream repository. You can try to find the definition file there. If you find your tablet model in the list, copy the file to the local machine.
You can create a new tablet definition file. Use the
data/wacom.examplefile below, and edit particular lines based on the characteristics of your device.
Example 20.1. Example model file description for a tablet
[Device] # The product is the product name announced by the kernel Product=Intuos 4 WL 6x9 # Vendor name of this tablet Vendor=Wacom # DeviceMatch includes the bus (usb, serial), the vendor ID and the actual # product ID DeviceMatch=usb:056a:00bc # Class of the tablet. Valid classes include Intuos3, Intuos4, Graphire, Bamboo, Cintiq Class=Intuos4 # Exact model of the tablet, not including the size. Model=Intuos 4 Wireless # Width in inches, as advertised by the manufacturer Width=9 # Height in inches, as advertised by the manufacturer Height=6 # Optional features that this tablet supports # Some features are dependent on the actual tool used, e.g. not all styli # have an eraser and some styli have additional custom axes (e.g. the # airbrush pen). These features describe those available on the tablet. # # Features not set in a file default to false/0 [Features] # This tablet supports styli (and erasers, if present on the actual stylus) Stylus=true # This tablet supports touch. Touch=false # This tablet has a touch ring (Intuos4 and Cintiq 24HD) Ring=true # This tablet has a second touch ring (Cintiq 24HD) Ring2=false # This tablet has a vertical/horizontal scroll strip VStrip=false HStrip=false # Number of buttons on the tablet Buttons=9 # This tablet is built-in (most serial tablets, Cintiqs) BuiltIn=false
20.2. Adding support for a new tablet
To add support for a new tablet into the
libwacom tablet information client library, follow this procedure.
The definition file for the tablet that you want to add exists.
For more information on ensuring that the definition file exists, see Section 20.1, “Preparing a tablet definition file”.
Add and install the definition file with the
# cp the-new-file.tablet /usr/share/libwacom/
Once installed, the tablet is part of the
libwacomdatabase. The tablet is then available through
Create a new
/etc/udev/rules/99-libwacom-override.rulesfile with the following content so that your settings are not overwritten:
ACTION!="add|change", GOTO="libwacom_end" KERNEL!="event[0-9]*", GOTO="libwacom_end" [new tablet match entries go here] LABEL="libwacom_end"
- Reboot your system.
20.3. Where is the Wacom tablet configuration stored
Configuration for your Wacom tablet is stored in GSettings in the
/org/gnome/settings-daemon/peripherals/wacom/machine-id-device-id key, where
machine-id is a D-Bus machine ID, and
device-id is a tablet device ID.
The configuration schema for the tablet is
Stylus configuration is stored in the
/org/gnome/settings-daemon/peripherals/wacom/device-id/tool-id key, where
tool-id is the identifier for the stylus used for professional ranges. For the consumer ranges with no support for
tool-id, a generic identifier is used instead.
The configuration schema for the stylus is
org.gnome.settings-daemon.peripherals.wacom.stylus. The configuration schema for the eraser is
20.4. Listing available Wacom tablet configuration paths
To get the full list of tablet configuration paths used on a particular machine, use the
gsd-list-wacom tool, which is provided by the
Make sure that the
gnome-settings-daemonpackage is installed on your system.
# yum install gnome-settings-daemon
To get the full list of tablet configuration paths used on your machine, run the following command:
tool-id in configuration paths allows for shared home directories with independent tablet configuration per machine. However, when sharing home directories between Machines, the Wacom settings apply only to one machine.
This is because the
machine-id for your Wacom tablet is included in the configuration path of the
/org/gnome/settings-daemon/peripherals/wacom/machine-id-device-id GSettings key, which stores your tablet settings.
