My Logitech wireless mouse has always been a bot over-sensitive, but
now, going into its 7th years of life, has become even more erratic. I
am not complaining about the speed, just the sensitivity. I have to be
very careful not moving the mouse too much in order not to close/open
windows, accidentally removing text, etc.
I have configured "mate-mouse-properties" to the lowest possible
sensitivity (changing the acceleration doesn't make much difference),
but it is still too sensitive.
This the output from xinput:

Any clue?
