Ok, first of all...Welcome!
Second, since you upgraded from Hardy to Intrepid you most likely have a big mess of dependencies and libraries mixed together...
First thing to check here is:
Are you using the gksudo before wminput commands?
Second thing to check would be:
Do you have libbluetooth2 and libbluetooth3 installed? If you have both (most probably you do since you upgraded) get rid of both by Completely Removing them with Synaptic and then installing libbluetooth3 only.
Most upgrades from Hardy to Intrepid end up in disaster and duplicated libraries...
Try these to steps first...and if it doesn't work, report back and let me know what happened.
As a side note: if these steps don't work, get your important data backed up since there's a 99% chance that a fresh install is in need to be done...most problems that emerge from faulty upgrades are extremely hard to fix...the only "easy" way is to backup, delete, format and install anew...sad but true.
