[Settings] Can't seem to change trackpad speed with xinput

[skurwielove]

Hello, I'm a total Linux noob so please bear with me. I'm trying to change my elan trackpad's speed on Kubuntu 18.04 with:

[FONT=monospace]xinput set-prop 11 301 3.000000
[/FONT]

but it returns me this error:

[FONT=monospace]X Error of failed request:  BadAccess (attempt to access private resource denied)
Major opcode of failed request:  131 (XInputExtension)
Minor opcode of failed request:  57 ()
Serial number of failed request:  19
Current serial number in output stream:  20
[/FONT]

Am I doing this right? The option in the settings is greyed out. Thank you for your time!

Try installing the old driver, I had to install it myself so my touchpad would work properly and the options would be available and not greyed out:

sudo apt install xserver-xorg-input-synaptics

and restart the system. Then check if the options are now available:



If it does not work just remove the installed package and reboot again:

sudo apt remove xserver-xorg-input-synaptics
