This bug also occurs for me on Ubuntu 14.04, on a MacBook Pro ( http://www.penlug.org/foswiki/bin/view/Main/HardwareInfoAppleMacBookProA1297 ) and since the touchpad is managed using Synaptics (synclient) there appears to be no need for the "mouseemu" program to be running or even installed on this machine.
I de-installed mouseemu as follows, and rebooted the machine, and now the Wacom Intuos4 works normally again: sudo apt-get remove mouseemu To avoid needing to reboot, I also tried the steps mentioned above, and that also got the Intuos4 working properly. sudo killall mouseemu sudo apt-get remove mouseemu sudo rmmod wacom; sleep 1; sudo modprobe wacom To get the pen pressure to be recognized by inkscape, the following workaround is still needed: export LIBOVERLAY_SCROLLBAR=0 inkscape -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xf86-input-wacom in Ubuntu. https://bugs.launchpad.net/bugs/1259048 Title: Intuos4 detected but non-functional To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xf86-input-wacom/+bug/1259048/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
