[Technology] Trackpad only scrolling

So I've run into a problem on my Lenovo Thinkpad Twist occasionally where my trackpad starts only scrolling, as though for every touch it senses two fingers (if I disable two finger scroll then the trackpad stops responding all together).  Googling had advice such as "modprobe -r psmouse; modprobe psmouse" which doesn't work on my Fedora install since psmouse is built-in.  Some people suggest using the hardware key for disabling and re-enabling your trackpad.  My Thinkpad Twist does not have such a key.  So, I ended up using xinput.



# find out the ID of my trackpad

$ xinput list    

# Ah, it's 12!  Then disable and re-enable it

$ xinput disable 12

$ xinput enable 12



Hooray, my trackpad works again.  Well, works as well as it ever did.  It's kind of hysterical on the Lenovo Thinkpad Twist.  If only I had the leisure to debug the actual problem. :)
