Similar or same problem here (ThinkPad X61 tablet) I use the tablet as multi-user.
On "first" user [ctrl+alt+f7] the pen does not work On "second" user [ctrl+alt+f8] the pen works. So, it's not a hardware issue. I don't know if it helps: /var/log/Xorg.2.log:[ 15853.585] (EE) PreInit returned 8 for "Serial Wacom Tablet stylus" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/234466 Title: [hardy] Pen crazy in tablet PC To manage notifications about this bug go to: https://bugs.launchpad.net/linuxwacom/+bug/234466/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
