I upgraded my Toshiba Protege M400 to Gusty and to my surprise the wacom input stopped working. After searching the internet without much success, I notice that there were two wacom devices,
/dev/input/wacom. Both were symlinks to
/dev/ttyS0, which makes sense as the tablet is basically a serial device attached to the notebook. In my
/etc/X11/xorg.conf I had the lines
Option "Device" "/dev/wacom"
under the wacom cursor, stylus, and eraser input devices. After changing the lines to
Option "Device" "/dev/input/wacom"
and restarting X, the input started working again. Why? I don’t know, as they both point to
Hopefully this is helpful to someone out there.
