I couldn't sleep last night so I got up, got some crackers, sat in my chair and what did I see? A Bamboo Fun sitting really, really close to my desk. Knowing that curiosity blooms into some of the greatest discoveries, I picked it up and plugged it in.
My first discovery was that it worked immediately in Fedora 15. I didn't have to add the drivers, as they are all ready installed. I could take the pen and migrate from screen to screen without lifting the pen.
My next discovery was it works with all the KDE paint applications as well as GIMP, Inkscape, and Scribus. GIMP has the most control of the pen and then Inkscape is the runner-up.
O.K. Here is the kicker. I could not get the Fun Tablet to work in F14 or F13. The only difference that I can see in F15 is that I do not have the Nvidia drivers installed. So, if you are having trouble with Bamboo on F15, I would check to see if your video drivers are overlapping. There can be just one. So, if you have two, they will negate each other and will produce zero work and frustrations will mount.
Sleep was overwhelming me so I put the pen down and went back to bed. Amazing things can be discovered during an insomniactic moment. The Wacom Bamboo Fun is just waiting for me over there.
