My tablet works fine except for the fact that I don't have any pressure sensitivity.
Any idea on how to fix this?
Edit: I have the same problem, but I can add that pressure sensitivity used to work under 11.04.
Which programs are you trying? There are problems in 11.10, gnome completely broke their wacom support and inkscape and gimp both can't use pressure sensitivity any more.
This is a known problem, which we hope will be fixed in the next release.
