Ok success booting now

Installed LXDE to test (as it was the smallest download). So I get the gdm login and onto the desktop, but...

What packages do I need to install to have the tablet hardware work?

The cursor does trail the stylus, but, up/down movements are reversed and i can't seem to select/click anything accurately on the desktop, even when carefully positioning the cursor.

UPDATE: I'm guessing this is an Xorg.conf issue, so compared it with the Mer version and seems to have all the same options set.
