I've just bought a Wacom Pen Partner and it works fine under X. You need to read the XF86Config man page and the XInput sections. Try looking at http://www.dorsai.org/~stasic/wacomx.htm The protcols that pads use are not mouse protocols. Wacom publish theirs in the developers section on the German site, but not on the US site. X supports Suma, Wacom and some one else's I think. The cheap no name brands may be Wacom protocols (5 bytes is about right) as Wacom sell the ICs to OEMs. > You may want to look at contrib/xmindpath, which sniffs serial > input and raise X11 event.

I'm currently hacking the X code to become a user land dameon which will generate some, but not all, X11 events (or others, it could go in moused). The only real way of using the pad as the mouse is with the X input extension. You can get the tablet to be the mouse for general use, in applications they can get extra information such as pressure. Apparenetly GIMP can use this and the above URL has a little pressure sensitive drawing program. Duncan PS. Using absolute mode to move around the display is very strange but you get used to it!
