There are several ways of setting mouse acceleration:
- by editing xorg configuration files
- the Template:Package Official package provides two programs that can be used to change those settings from a shell or a script:
- many Desktop Environments provide a configuration GUI for mouse settings. They should be easy to find and use.
Setting mouse acceleration
In xorg configuration
man xorg.conf for details.
You can also assign settings to specific hardware by using "MatchProduct", "MatchVendor" and other matches inside class sections.
To get the current values, use:
xset q | grep -A 1 Pointer
To set new values, type:
xset m ACCELERATION THRESHOLD
where ACCELERATION defines how many times faster the cursor will move than the default speed, when the cursor moves more than THRESHOLD pixels in a short time. ACCELERATION can be a fraction, so if you want to slow down the mouse you can use 1/2, and if 3 is slightly too fast, but 2 is too slow, you can use 5/2, etc.
To get the default settings back:
xset m default

First, get a list of devices plugged in (ignore any virtual pointers):
Take not of the ID. You may also use the full name in commands if the ID is prone to changing.
Get a list of available properties and their current values available for modification with
xinput list-props 9
9 is the ID of the device you wish to use. Or
xinput list-props 'Bobs mouse brand'
Bobs mouse brand is the name of your mouse given by
Example, changing the property of
Constant Deceleration to 2:
$ xinput list-props 9 Device 'Bobs mouse brand': Device Enabled (121): 1 Device Accel Profile (240): 0 Device Accel Constant Deceleration (241): 1.000000 Device Accel Adaptive Deceleration (243): 1.000000 Device Accel Velocity Scaling (244): 10.000000 $ xinput --set-prop 'Bobs mouse brand' 'Device Accel Constant Deceleration' 2
Disabling mouse acceleration
Mouse acceleration has changed dramatically in recent X server versions, using
xset to disable acceleration doesn't work as it used to and is not recommended anymore.
Recent changes on
PointerAcceleration can be read here.
To completely disable any sort of acceleration/deceleration, create the following file: Template:File
