Through troubleshooting a different bug, I've found a quantal kernel that recognises the tablet (see this bug https://bugs.launchpad.net/ubuntu/+source/xf86-input-wacom/+bug/1033783 )
The libwacom in quantal still does not let you calibrate the tablet using the settings panel -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libwacom in Ubuntu. https://bugs.launchpad.net/bugs/985975 Title: [wacom]: won't calibrate X220t To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/985975/+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
