This tutorial will show you how to install wacom tablet drivers on Ubuntu 12.04, 11.10 and 11.04 to make your wacom work properly.
Open terminal from the dash home or press Ctrl+Alt+T, add ppa:lekensteyn/wacom-tablet to your system’s repository:
sudo apt-add-repository ppa:lekensteyn/wacom-tablet
Update and install wacom driver:
sudo apt-get install input-wacom wacom-dkms
The wacom-dkms package installs an updated kernel module, “wacom”, using DKMS. DKMS takes care of updating the kernel module each time your kernel is upgraded, so you only have to install this package once.
After installation, unload the old kernel driver and reload the new one with:
sudo modprobe -v -r wacom; sudo modprobe -v wacom
After doing so, your device should immediately be recognized
