I am using my Mint desktop with a USB mouse. Nothing unusual about the mouse. It is a Logitech wired USB two-button, wheel mouse that I picked up from a local office supply store. The pointer moves way too fast for my taste. Even my daughter said it was way too fast.
The solution usually is to adjust the speed sliders in the Mouse section of System Settings. I already set them to their slowest settings, so something needed to change under the hood. This web page had the answer:
http://patrickmylund.com/blog/lowering-gaming-mouse-sensitivity-in-ubuntu-9-10/
In Mint I found that the first command to run in terminal is “xinput -list” which will give some information about your pointing device. Mine says my mouse is “ImExPS/2 Logitech Explorer Mouse”. Then this command is all it took to slow down the mouse:
xinput -set-prop “ImExPS/2 Logitech Explorer Mouse” “Device Accel Constant Deceleration” 3
With some experimentation I determined that the higher the number at the end of that command, the slower the mouse will move. For me, “3” worked out nicely.

Thanks!!! I’ve been looking for how to do this for like ever!! How did you figure it out?

Worked fine for me. Thanks very much for the tip!

Just what I was looking for after seeing the System Settings had my mouse speed at the lowest!

Thanks! I also found this article (https://wiki.archlinux.org/index.php/Mouse_acceleration) and after doing “xset mouse 3 6” I got back the long-distance acceleration, giving best of both worlds.

Thanks! I was going to give up on Mint because of this. It’s crazy that it is still not a standard feature to change the mouse sensitivity.

In some distros, the Sensitivity slider algorithm is backwards. So first check to see if setting the sensitivity to High perhaps makes the mouse action really slow.

I just solved my Dell bluetooth mouse scrolling way toooo fast by turning it off and removing from Bluetooth Devices and re-adding it after it was turned on (of course) then totally normal.

Thanks! I set mine to 1.5 and it is perfect now 🙂

Thanks, That worked just fine for mee
i used xinput -set-prop “9” “Device Accel Constant Deceleration” 5
for there was confusions in mij list
xinput -list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech USB Receiver id=9 [slave pointer (2)]
⎜ ↳ Logitech USB Receiver id=10 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]

Great thanks!

Thank you! I’ve just switched to Mint Linux yesterday and was already getting pissed off by that super fast, Speedy-Gonzalez-like mouse. However, now I’m really enjoying my new system! 🙂

Thanks artstadlin! Works for me in LMDE2 Betsy.

Thank you for that tip. Works nicely

I’ve been looking for this for one whole week. Thanks a lot.

Thanks for this, I first tried using xset to change the speed from 2/1 to 1, which slowed my mouse down some, but fractions below 1 like 1/2 didn’t seem to slow it down any more. Using this instead with a setting of 5 worked for me.
January 22, 2016 at 8:24 PM
On second thought, a setting of 4 feels just perfect for me! Thanks again!

Thank you for this, very helpful!! It was annoying to use super fast mouse. Without your advice the fresh installed Linux Mint would be useless. I wonde, why is mouse speed slider still not fully functional in Linux Mint after several years?
