I have just connected Wacom Bamboo CTL-470K-RUPL to my Ubuntu 13.04 (up-to-date 10/26/2013). Everything works fine except an eraser. More precisely, nothing happens when I try to use it (even in GIMP with Preferences ? Input Devices ? Eraser configured). $ sudo dpkg reconfigure xserver-xorg-input-wacom doesn’t help either. How should I re-configure my Wacom tablet to enable eraser? Thanks in advance.
