Hallo
I do not have a Wacom tablet and am not an creative graphics person. That being said, I hope the information below might help someone. The very last post shows that you might have an easier experience using another GNU/Linux distro, however, I would remind you that this does not mean you have to leave Ubuntu-Mate behind - you could dual-boot or run a second distro in a virtual machine...
If you go to the Wacom website and enter "Linux" in the sites own search field it returns only on result, for the Model DTH-1152.
When you read the information presented for this model there is a link to the site:
http://linuxwacom.sourceforge.net/wiki/index.php/Device_IDs
here you'll find a message that the site has moved to:

Hopefully you will be able to get your tablet working with GNU/Linux.
