And on goes the love/hate relationship with Linux. Setting up my Cintiq is one of the things that makes me really loathe it and want to go jumping back onto my iMac and ignore the possibility of art on Linux forever. My first attempt was an abysmal fail (I blew up Unity and had to spend a bit of time fixing it and it never completely recovered, and due to the nature of the child who owned that particular machine it ended up with Win7 on it). If I didn't need a Linux server for web dev (which is why I got the laptop) I would have just bought a MacBook.
Don't care about the rambling documentation? No worries, just copy/paste the script. You may need to change some button assignments for your setup.
This is probably not necessary but first I grabbed latest Nvidia drivers.
sudo add-apt-repository ppa:xorg-edgers/ppa -y
sudo apt-get update
sudo apt-get install nvidia-340
