Uhhuh.

Let me give you an example.

If you have a mouse with a high DPI behavior, Ubuntu
refuses to scale the DPI down and give the mouse normal
behavior.

We're told to "unplug the mouse and plug it in again".
Upon rediscover, for some reason, the scaling then
works properly.

And this "workaround" has been the answer "forever" :-/

Wunderbar. Ausgezeichnet.

I have two mice on the Test Machine. A Logitech mouse
(with conventional DPI) and a newer MS Mouse (with high DPI).
I got the MS Mouse, because that's all they had at Staples.

And I'm expected to unplug and plug that MS mouse in
over and over and over and over and... You get the idea.
The connector would have fallen off by now, if I had
followed that advice scrupulously.

Because "we're not fixing it". For some value of
"we're not fixing it".
