Being a laptop, my laptop also has a touchpad. So there are two input devices. I suspect that is the source of the problem. Is there any tweak that will make the Control Center Mouse control suitable for laptops with an external mouse?
The Logitech mouse is a bit too sensitive, and I would like to turn it down. The Control Center does not support this. If I go to the Control Center, there is a Mouse icon. If I click it, there are two tabs: General and Touchpad. The latter tab only has controls to say how the touchpad emulates a mouse. Only the General tab has Acceleration and Sensitivity sliders. There is nothing to select which device is being controlled, but it doesn't matter; as far as I can see the sliders don't seem to affect EITHER one!
After googling, I came across gpointing-device-settings. Installed it from Synaptic. It recognises the two devices, but does not offer sensitivity for the logitech.

I found some instructions for changing the mouse sensitivity using xinput --set-prop. This worked after some experimentation, so this is not a driver issue. The hardware and the software currently on the laptop can change the mouse sensitivity, it's just that this is not available from the Control Center.
For reference, here's me changing the sensitivity:
Code: Select all
laptop ~ # xinput --list --short
