I also have this issue. It's a bit annoying, as my pen worked on 9.10,
and suddenly, it's stopped. Unfortunately, my eraser doesn't work any
more, so I can't test if it's exactly the same issue as above; but it
seems to me that it probably is. Only sees eraser. Running up Gimp
recognises the pen
Incidentally: I did have it 'working' once since being on 10.04. It
didn't work properly - the pen would only register location when
pressing down. Anyway, next time I booted (after some messing about to
try and make it work properly) and it didn't work again.
