I have an Apple Magic Mouse, and it's almost unusable since the sensitivity is too high. Yet in the Mouse/Touchpad settings, the pointer speed is set to the slowest possible setting. Is there a way to manually change this setting so that it's much slower than the slowest setting?

The easiest way of doing this is xset m. The general format is:

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.

For example:

xset m 1/2 4

To get the current values, use:

xset q | grep -A 1 Pointer

    @guettli depends on what you are doing, how you are connecting to the machine etc, but usually, just adding xset m 1/2 4 to your .bashrc will be enough. If not, or if you sometimes connect non-graphically, you might want to post a new question about that. – terdon Oct 27 '17 at 10:52
