Corsair M95 Gaming Mouse too sensitive / speed too fast. How to reduce speed?

  • 772

The mouse control panel window slider does nothing. The official thread does not seem to affect this particular mouse due to it's xinput props being different: Reduce the Mouse Sensitivity

Here's what I've tried:

xinput set-prop 9 "libinput Accel Speed Default" 2.88

X Error of failed request:  BadAccess (attempt to access private resource denied)
  Major opcode of failed request:  131 (XInputExtension)
  Minor opcode of failed request:  57 ()
  Serial number of failed request:  20
  Current serial number in output stream:  21

And:

xinput set-prop $MOUSE_ID "Device Accel Constant Deceleration" 2.88 

property 'Device Accel Constant Deceleration' doesn't exist, you need to specify its type and format

Here are the props:

  1. Best Answer

    I was super close:

    xinput set-prop $MOUSE_ID "libinput Accel Speed" -0.9

    Where 

    MOUSE_ID=`xinput list | grep -i Corsair | awk '{print $(NF-3)}' | cut -c4-5 | head -n 1

    Per: https://patrickmn.com/aside/lowering-gaming-mouse-sensitivity-in-ubuntu-9-10/

  2. For those who don't have Device Accel Constant Deceleration like me.

    The values for libinput Accel Speed can be negative, e.g.

    xinput --set-prop 'pointer:Logitech MX Master' 'libinput Accel Speed' -0.5

    To find your mouse name: xinput | grep pointer, don't forget to prefix it with pointer: as my mouse shows up as a keyboard too.
