for the record, i had:

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Mouseemu virtual mouse id=11 [slave pointer (2)]
⎜ ↳ Apple Wireless Mouse id=13 [slave pointer (2)]

and what does the job is the mouseemu virtual mouse. i wonder why, but it works. thanks again!

Not as far as I know. I’ve been setting my Constant Deceleration to 60 and 70 at times — in 10.10, too.

Try keeping Velocity Scaling at 1, but set Constant Deceleration to something like 50. If you still don’t feel any difference, I wager that the device ID/name you’re changing isn’t the right one. Sometimes your device will show up in xinput --list multiple times with a bunch of similar names, but only one of the entries will actually affect your pointer.

Hope that helps.

i’m under 10.10 and recieved for christmas an apple magic mouse that is waaay too fast. i followed your guide but it seems to me that changing those values don’t actually affect my mouse’s speed, or if they do, it’s very little. do those value have limits?

thanks
