The input-wacom driver is a set of loadable kernel modules which allows new tablets to be used with systems using kernels as old as Linux 2.6.30. While this gets many of the updates that are pushed to the upstream Linux kernel driver, some differences may exist. This will be particularly apparent for users of older kernels. Because of this, we recommend upgrading your kernel if possible and only installing this driver when absolutely necessary.

This driver builds two seperate kernel modules: wacom.ko and wacom_w8001.ko. The former is used with tablets that interface over the USB bus, which accounts for the vast majority of tablets. The latter is used for older tablet PCs whose digitizers are connected via a serial interface. The hid-wacom.ko and wacom_i2c.ko modules (for Bluetooth and I2C tablets, respectively) are not included with this driver -- updates to these are only available through kernel updates.




Before building, you'll need to ensure the necessary dependencies have been installed on your system:

sudo apt-get install linux-headers-$(uname -r)  # on Debian, Ubuntu, Mint
sudo yum install gcc kernel-devel               # on RHEL, CentOS, Fedora


Please download the latest release from the sourceforge download section and unpack it with:

tar xjvf input-wacom-<version number>.tar.bz2
cd input-wacom-<version number>

Build / Install

From within the extracted input-wacom directory, run the following commands to build the driver and install it where your system can find it. The output from the configure step will provide the exact path for you to use for copying.

sudo cp ./<kernel version>/wacom.ko /lib/modules/`uname -r`/kernel/drivers/input/tablet
sudo cp ./<kernel version>/wacom_w8001.ko /lib/modules/`uname -r`/kernel/drivers/input/touchscreen
sudo depmod -a

Module Loading

Finally, you'll need to have the module loaded by the kernel so that it can be used by the rest of the system. The easiest way to do this is to simply reboot; the kernel will automatically load the newly-installed module when necessary. Alternatively, you can use the commands below to force the running kernel to reload the module without rebooting:

sudo modprobe -r wacom
sudo modprobe -r w8001
sudo insmod /lib/modules/`uname -r`/kernel/drivers/input/tablet/wacom.ko
sudo insmod /lib/modules/`uname -r`/kernel/drivers/input/touchscreen/wacom_w8001.ko


If you are developing support for new devices, please develop against upstream kernels first. Patches in input-wacom may not find their way into upstream kernels. Once a device is supported upstream, feel free to submit patches for backported support to the linux-input mailing list.

The input-wacom driver is available through git for developers to hack on. Before using it, you should install your distribution's git, autoconf, and automake tools. Afterwards, you may clone the repository as follows:

git clone git://git.code.sf.net/p/linuxwacom/input-wacom linuxwacom-input-wacom
cd linuxwacom-input-wacom

Note that the configure script will not exist when building from git. We provide a helper autogen.sh script that wraps executing the autotools steps as well as executing the configure step. After running it, you can either install the modules as normal, or use insmod with the files directly in the build directory.

X driver

Upgrading both the kernel driver and the X driver to the same version is recommended. Please see xf86-input-wacom for the X driver required for X servers 1.7 and later.
