I have a Genuis Easypen M610X Tablet connected to my Kunbutu desktop computer. It can respond and move the curser and click as well. But when I used it for Krita or Gimp it won't draw anything. I found that Kunbutu alone has yet to make it compatible yet for my version of the tablet.
I'm having trouble getting a setting to stick. Under System Settings>Graphic Tablet>Tablet>Tablet Mapping>Map Tablet Area to Screen>Screen, there is a setting which maps the graphic tablet area to the available monitors. I need the wacom to only map to the wacom, not all three screens. There's a button, "Toggle Screen," which does this, and everything works great.
