Linux Mint, Apple Magic Mouse middle scrolling stopped working

Im using linux mint 18.3. linux kernel 4.15.0-29-generic.

Seemingly randomly a while ago the middle mouse scrolling on my Apple Magic Mouse stopped working. It works on a Mac so I'm sure it's not the mouse

'John Doe’s Mouse' listed below is my mouse.

xinput --list
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad                id=13   [slave  pointer  (2)]
⎜   ↳ John Doe’s Mouse                  id=15   [slave  pointer  (2)]

Do you see anything wrong with the above which could cause this?

edit:

evtest /dev/input/event17 and then xinput --test

xinput test output https://pastebin.com/7VyWAmAd

Have you tried in another computer? – None – 2018-09-11T13:37:36.627

@GabrielaGarcia It works on a Mac so I'm sure it's not the mouse – Fred joe – 2018-09-11T13:39:26.150

Please [edit] and add that information. Otherwise everybody else will suspect hardware failure as I did. – None – 2018-09-11T13:41:19.860

The way to debug this is to first use evtest /dev/input/event17 (with the current number, may change between boots) and then xinput --test 15 (with the current number), and look if you get events for middle mouse scrolling, and if yes, which events. That will tell you where to look for a wrong configuration. – dirkt – 2018-09-11T13:45:13.497

@dirkt No command 'evest' found, – Fred joe – 2018-09-11T13:47:10.150

Sorry, evtest. – dirkt – 2018-09-11T13:48:16.647

@dirkt added output to the first post – Fred joe – 2018-09-11T13:53:20.040

You are getting normal mouse movement instead of scrolling (unless you did mouse movement during the test). Next thing to try is to use xinput set-prop ... to activate the various scrolling methods. Start with xinput set-prop 15 291 0 0 1, verify with --list-props, see if anything changed. Then 286 (natural scrolling), then disable 291 again. – dirkt – 2018-09-11T14:03:34.410

Oh, and the "seeming randomly a while ago" is probably correlated to when you upgraded your system and changed to libinput from whatever you used before. – dirkt – 2018-09-11T14:04:31.693

@dirkt output here https://pastebin.com/MssTNiHw it didn't seem to like 286

– Fred joe – 2018-09-11T14:19:54.403

xinput set-prop 15 286 1 of course - compare with the value in --list-props. – dirkt – 2018-09-11T14:22:00.160

And the idea is to test each of these, in all combinations. – dirkt – 2018-09-11T14:23:02.430

output for that https://pastebin.com/cg9wh2Ua

im not sure i want to mess too much with it since i dont understand what 0, 0, 1 etc means?

also is reboot needed to apply each change or not? – Fred joe – 2018-09-11T14:24:41.653
