"Button order chaos" is perhaps a more apt description than you realize... Unfortunately, Bamboo tablets aren't really well-supported by the control panel in GNOME at this time. The button mapping issue is known, and stems from a fundamental difference in how the kernel presents buttons on a Bamboo tablet. To boil it down to the core, Bamboo devices end up "skipping" some button numbers, which is not a situation that libwacom and gnome-control-center can handle gracefully. I've tinkered in the past with trying to make xf86-input-wacom present a cleaned-up interface, but because of the variety of ways that a Bamboo tablet can number its buttons, I wasn't able to come up with any kind of a solution. That said, it is possible to work around the issue with some effort. I've attached a script that does most of the work. You can run it as `./wacom-gnome-compat.sh <id>` with the ID number of your pad device reported by xsetwacom. It will re-map the buttons to produce events that the script can listen for, at which point it will begin asking you to begin pressing each button or 'q' when finished. Once you've pressed all the buttons and then hit 'q', it will change the mapping a second time, this time to a condensed form that should allow GNOME to use all the buttons. It also prints out the commands that create this mapping, in case you want to save them e.g. to a startup script. As for why you can't set the buttons to produce left/middle/right mouse clicks through the control panel? Unfortunately, the GNOME developers don't feel that mouse buttons are worthwhile shortcuts and have resisted attempts to add them in. Worse, because GNOME's button-mapping magic works by intercepting mouse events sent from our driver, you can't use xsetwacom to force a specific button to make a click: the event will just be consumed by GNOME before anything can see it :( Jason --- Now instead of four in the eights place / you’ve got three, ‘Cause you added one / (That is to say, eight) to the two, / But you can’t take seven from three, / So you look at the sixty-fours....
