Chrome OS: Entirely disable mouse accelaration

 

Chrome OS is light weighted. That means users have few options to customize it into forms suitable for themselves.

One of the missing features is disabling mouse accelaration. Under current design, user can only adjust “mouse pointer speed” in the Settings page. No accelaration adjustment. Accelaration is meaningful for touchpads. But for external mice, it’s awkward. At least true to me.

In older versions of Chrome OS, one can find a way to disable accelaration by typing xset m 0 in the terminal console. In later updates, xset is deprecated with no successor at all.

With the latest beta channel update, it’s possible to achieve that again. But the command becomes much more complicated.

That’s the way Google makes simple life not simple.

inputcontrol –mouse_custom_point_accel=\
inf,0,4,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0,\
inf,0,1,0
inputcontrol –use_mouse_custom_point_accel=1

Note: the “4” in the second line is the linear speed that you may want to change. With the last line of command, Chrome OS will pick up user definition of mouse accelaration, ignoring the “mouse speed” option in the Settings page.
