Mouse Sensitivity in control center, not working

Post by fpeelo »

Am running Mate 17.1, upgraded from a clean install of 17, with Mate. I have a Dell Inspiron 6400 laptop, and a Logitech M185 wireless USB mouse.

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.

From
https://patrickmn.com/blog/lowering-gam ... untu-9-10/
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
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ Logitech USB Receiver                   	id=9	[slave  pointer  (2)]
⎜   ↳ Logitech USB Receiver                   	id=10	[slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad              	id=12	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Video Bus                               	id=6	[slave  keyboard (3)]
    ↳ Power Button                            	id=7	[slave  keyboard (3)]
    ↳ Sleep Button                            	id=8	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=11	[slave  keyboard (3)]
    ↳ Dell WMI hotkeys                        	id=13	[slave  keyboard (3)]
laptop ~ # xinput --set-prop "Logitech USB Receiver" "Device Accel Constant Deceleration" 5
Warning: There are multiple devices matching 'Logitech USB Receiver'.
To ensure the correct one is selected, please use the device ID, or prefix the
device name with 'pointer:' or 'keyboard:' as appropriate.

unable to find device Logitech USB Receiver
laptop ~ # xinput --set-prop 10 "Device Accel Constant Deceleration" 10
laptop ~ # xinput --set-prop 10 "Device Accel Constant Deceleration" 1
laptop ~ # xinput --set-prop 9 "Device Accel Constant Deceleration" 1
laptop ~ # xinput --set-prop 9 "Device Accel Constant Deceleration" 10
laptop ~ # xinput --set-prop 9 "Device Accel Constant Deceleration" 3
Changing the properties on device 10 seemed to have no effect. Changing it on device 9 worked. I don't know why the Logitech appears twice in the xinput list. gpointing-device-settings only sees one Logitech.

I don't know for sure if this will help, but it may be worth a try. I replied to this post about mapping logitech buttons, but lomoco also can control sensitivity.

Hi Richyrich

Thanks for the reply. It was worth a try[1] - unfortunately, lomoco -i just says
005.002: 046d:c52f Unsupported Logitech device: Unknown
so it doesn't look like it's going to help in my case. I suppose the question I should be asking is:

how do I report this bug?

Because the fact that the control panel does not indicate which mouse is being controlled, and doesn't seem to have any effect on either the Touchpad or the Manx mouse[3] while xinput is able to change the mouse sensitivity, definitely looks like a bug to me.

Frank
[1] The option to change from 800cpi to 400cpi[2] looked promising.
[2] What's cpi? Used to be Characters Per Inch when I had a dot-matrix printer - I thought mice measured distances in Mickeys?
[3] calling it that because it has no tail, like the Manx cat.

Did you ever resolve this? I'm having the same issue on Serena Cinnamon. (I'll make a new thread about it...)
