I installed Linux Mint 15 (cinnamon) and am really loving it
With the help of the internet I finally figured out how to access the Wacom control panel GUI!
Basically, you need to install "gnome-control-center" (type it in the terminal and it'll help you)
Next, for easy access, I copied "Wacom Tablet" to the desktop (found in "/usr/share/applications")
edit: this doesn't work in Linux Mint 16 cinnamon
