Ubuntu 12.04 Upgrade Busted My Mouse

OK.  I’ve upgraded my VM to the latest and greatest Ubuntu 12.04. It’s pretty snappy and I’m still using XFCE since I still can’t bring myself to like Gnome. One problem that has plagued me this week has been my mouse. My mouse behaves strangely every time I right click. The menu option that appears immediately below the position of the cursor is selected. This drove me insane while working in Eclipse. Imagine that a right click could randomly select “Delete” or “Rename”. Not too good while your coding. I’ve seen countless complaints about this in many versions of Ubuntu, but no solutions:


After messing about, I noticed that I have two devices registered:

[acalbaza@ubuntu ~]$ xinput
? Virtual core pointer                    	id=2	[master pointer  (3)]
?   ? Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
?   ? ImPS/2 Generic Wheel Mouse              	id=8	[slave  pointer  (2)]
?   ? ImPS/2 Generic Wheel Mouse              	id=9	[slave  pointer  (2)]
? Virtual core keyboard                   	id=3	[master keyboard (2)]
    ? Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ? Power Button                            	id=6	[slave  keyboard (3)]
    ? AT Translated Set 2 keyboard            	id=7	[slave  keyboard (3)]

If I disabled #9, things work as expected. How irritating, but I hope it helps someone else!
