Hi I've had a problem with the "Bamboo Touch and Pen" on my laptop : the pointer sticks to right edge of the screen and never responds to changes in horizontal direction. The X log shows absurd negative X dimensions in messages that state about "top X=.... top Y=... bottom X=... bottom Y=... resol X=... resol Y=...".
It appears that the driver faces a division by zero when trying to deal with the "KeepShape" option on that computer. The fields "priv->maxWidth" and "priv->maxHeight" are both set to 0 - don't ask me why - making it impossible to assess the screen ratio. I've patched (attached) to detect and disable KeepShape in the situation. This does not solve the problem, which is somewhere else, but makes however the driver more robust, removing an option when it cannot possibly deal with. Bruno NB Augmenting the debuging level in X configuration (50-wacom.conf: Option "DebugLevel" "100"), without any modification to the source, shows something like : screenRatio = -nan, tabletRatio = 1.6
