My Wacom Intous art "Creative Pen & Touch" CTH-490, which I bought today, does not work with ubuntu 15.04. When I go to settings -> Wacom tablet, I see that there is no tablet detected, even if the tablet itself seems connected (the blue light is turned on) I tried to Google the problem and download some drivers but nothing worked.
May you help me to solve the problem? I do not have any windows computer, and using that tablet is an important thing for me.. Thanks! :)
