In fact, I have not been able to use my Wacom Tablet with fancy KDE-settings (systemsettings) under an untouched Mint (tryed with Ubuntu based and Debian based), yet you can tweak it a bit and make it work and access happily to most of config in KDE-config and let it work.
To achive this I made a fresh Linux Mint 17 LTS Xfce install and installed not only systemsettings but also kwin (sudo apt-get install kde-window-manager) which is the composite window manager used by KDE. Might seem strange but you will get your original desktop (Xfce in my case, but might be MATE, Cinnamon, Unity, Gnome or whatever) with another window manager (that you'll see in window decorations, fancy bouncy icon of loading application beside the cursor and that kind of fancy KDE stuff, and also window capabilities provided by kwint, such as invert colors, transparency on the fly and others.
To switch to kwin you should execute:
kwin --replace
Wich can be done at startup. And to return to previous mode:
<your-previous-window-manager> --replace
In the case of Xfce:
xfwm4 --replace
But in any case expect some fails, reboots, requirement of KDE services ...
Update: Managed to have the fancy KDE wacom system settings.
After some research, I wonder if the kde tablet service was actually running or not, so, tried modifying some config after reading this https://forum.kde.org/viewtopic.php?f=22&t=37365
In a terminal:
cd /usr/share/kde4/services/kded #where your kde dir might be
sudo cp wacomtablet.desktop wacomtablet.desktop.old #just in case I broke something
sudo gedit wacomtablet.desktop #can use nano, vi, or your favorite editor
changed this line in the file wacomtablet.desktop:
X-KDE-Kded-phase=0 #was before 1 in my case.
Restart KDE services:
kded4
Done!
Tell us if it works for you!
