Hi,

When I change the mouse settings they don't take effect.

I have Ubuntu 18.04 with KDE Plasma 5 Enviroment.

Everything else works perfect.

Thanks!

You should be more specific. What do you change and expect after the change?

Hi fdekruijf,

None of the settings take effect. If I set everything to max, the cursor moves in the same speed.

I want to speed up both the mouse wheel and the cursor.

I would prefere to fix the GUI but a fix from terminal would also work.

xinput --list --short

I have Logitech USB Receiver

xinput --set-prop "Logitech USB Receiver" "Device Accel Constant Deceleration" 1.5

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.

What would be the correct code with "id9"? Or GUI fix?

Thanks

im on kubuntu 18.04.1 and notice the scrolling speed doesnt change for me either.

This is a known bug in the base packages starting I believe in v17.04 and hasn't been fixed for 18.04:

Make sure you do it in the following order or you will be left with no input software - basically you need to apt-get install xserver-xorg-input-evdev package then apt-get remove the xserver-xorg-input-libinput package. Restart and you will have sensitivity and acceleration functionality again.

Much appreciated, thanks !

Just realized touchpad is not found... Everything else works fine.

That's a known bug with certain models of laptops with touchpads - some are not recognized properly, not sure if it's a config or driver issue. Try the 3 step answer here:

Thanks very much!

sudo apt install xserver-xorg-input-synaptics

and reboot.

Did it.
