Bruno, I am not sure whether what I observe is a bug in Ubuntu or GIMP so, I will state my observations and look for advice. Just to confirm, I am using Ubuntu 10.04 RC, Wacom Bamboo tablet and GIMP 2.6.8.
Firstly, the cursor pointer and the circle indicating the size of a brush do not coincide. Further, the movement of the circle does not follow the movement of the pointer. Secondly, the script which sets up the buttons and which worked in Ubuntu 9.04 and 9.10 does not work in 10.04. The script is attached. There is a further problem which is not connected with the Wacom but I include the reference to the bug report because it may be useful. https://bugzilla.gnome.org/show_bug.cgi?id=612956 Norman
