Was configuring my mouse, stumbled at Mouse Too Wild?
6 years later, Mate mouse settings are still totally misleading and confusing.
- Is described in documentation as "Use the slider to specify the speed at which your mouse pointer moves on your screen when you move your mouse.", which is wrong on oh so many levels.
- Actual setting /org/mate/desktop/peripherals/mouse/motion-acceleration is described as "Acceleration multiplier for mouse motion. A value of -1 is the system default.", much better description, so just copy/paste it to docs.
- As soon as you touch "Acceleration" slider, there is absolutely no way to reset it back to default -1 value, it goes on 1 to 10 scale. Which in turn gets translated to libinput "Accel Speed" ranging from -1 to +1.
- Is described in documentation as "Use the slider to specify how sensitive your mouse pointer is to movements of your mouse.". Uh, what?
- Actual setting /org/mate/desktop/peripherals/mouse/motion-threshold is described as "Distance in pixels the pointer must move before accelerated mouse motion is activated. A value of -1 is the system default.", again much more sensible, just is it in help.
- Same problem with slider, no way to reset to default -1 value.
And big the elephant in room: in order to change actual pointer speed in modern Linux stack, you have to mess with MOUSE_DPI libinput setting.
Mate gives you zero control over actual speed, acceleration controls are nothing but band-aid.
