You didn't answer my question about why you need to run that command. Are you having a problem with the mouse action? You can
run this command to get your present mouse acceleration values:
xset q | grep -A 1 Pointer
You will probably get the result: acceleration: 1/1 threshold: 1
which are the values in your command.
If you're trying to decrease mouse acceleration then decrease the first number, such as: xset m 1/4 1
If you're trying to increase acceleration then increase the first number, such as: xset m 2 1
To run the command automatically go to Menu > Preferences > Startup Applications. Click on "Add". In the new window under "Name"
you can put any name. In the "Command" window put : xset m 1 1
