Public bug reported:
I'm using Ubuntu 16.04, (stock install 16.04.3, not HWE LTS) with a newly
bought mouse, Logitech M705 (which are using Logitech Unifying Receiver). When
I connected the mouse everything was working as expected, except that the
middle clicking wasn't working. The mouse has the following map:
1 Left
2 Middle (push roller down)
3 Right
4 Roller Forward
5 Roller Back
6 Roller tilt left
7 Roller tilt right
8 Side button, forward
9 Side Button, rearward
10 Extra button (app switching)
When I tried the mouse with 'xev | grep button', the button Left was nr
1, Right nr 3, Roller Forward nr 4, Roller Back nr 5, Roller tilt left
nr 6, Roller tilt right nr 7, Side button, forward nr 8, Side Button,
rearward nr 9 and Extra button was nr 10. But Middle button was the same
as Roller tilt left namely nr 6. It should have been number 2 not 6.
Thus the middle click button wasn't properly detected and not working as
expected. I can remap the mouse button nr 6 to nr 2 with xinput and get
middle clicking but then the left tilt functionality disappear, this
button (nr 6) also become a middle click button, nr 2. What is it that
makes that two different buttons get the same number?
xinput list shows:
