If you have a USB tablet, I need to know your exact model of your wacom
tablet. In order to give you a proper set of "input devices" for your
xorg.conf

Cheers.


Thanks for your reply.
I have installed the wacom-tools and the xserver-xorg-input-wacom packages, and I have configured the input devices in xorg.conf the same way I had on Ubuntu (where my pen tablet used to work), but I still get no input (always after modprobing).
I can see the pen tablet is recognised on /dev/input/wacom and on /dev/input/event$ (where $ changes at every reboot), using wacdump, but there is no evident input, namely, when I move the pen, no digits appear.
I have also tried to follow this guide, which is a bit outdated, but I thought it was worth a try: http://www.i3s.unice.fr/~ol/success.html

It is a USB tablet and the model is Volito 2.

Thanks for your time.


I have read somewhere that the pen tablet should work out of the box, after modprobing it. So I did a clean re-installation (since in my previous one I did not install the Desktop Environment by default) including the Desktop Environment, just to be sure. I plugged my pen tablet in, and no joy. So I tried installing wacom-tools, and configuring the input devices in xorg.conf. Still, the pen tablet is not working. I really wonder where is the problem. Maybe it is just a little detail I am missing.

Should I open a new thread with the title: "Debain Etch: Wacom Volito2 not recongnised"?

Thanks for your time.
