Comment 7 for bug 234466

A few data points:

1) I had this problem under gutsy. I found that suspending and resuming my thinkpad x41t would fix it nearly every time.

2) I reinstalled with Hardy recently on the same machine and found that I was having suspend/resume issues. In previous versions of Ubuntu, I've had to add a setserial command to my resume scripts to get stylus back after suspend, but that didn't help in this case.

3) To furthure what Luca said: Grabbing the intrepid packages for the wacom driver (more recent version) seems to give me a completely problem free wacom stylus after 24 hour or so of testing. I have no erratic cursor movement and no suspend/resume problems. I still have the setserial command (/bin/setserial /dev/ttyS0 port 0x0200 irq 5 autoconfig) in a /etc/acpi/resume.d script. Since these packages can be installed under hardy with no dependency issues, I would recommend that anyone having trouble try that route.
