I brought a Logitech Wireless Touch Keyboard K400r and plugged it to my laptop, OS is Ubuntu 14.04. It worked just out of the box. However the problem I noticed that its trackpad is very slow and I wanted to change its settings. Setpoint software which Logitech provides to customize keyboard option doesn't have a linux distribution. The only option which I find for Ubuntu was Solaar app. Though it has some options, but do not include trackpad settings. Is there any workaround of trackpad settings available for this Logitech wireless keyboard running on Ubuntu? Basically I am looking for Logitech Setpoint alternative in Ubuntu.

Update --

After searching a lot, I found hidpoint which seems to be not active anymore.

  • Solaar is the unofficial SetPoint alternative for Linux, can't you control cursor speed through the normal mouse settings?

  • The default keyboard settings is only controlling laptop's inbuilt keyboard. No option to control Logitech's wireless one. I understand that Solaar is not official. I tried searching something related to Logitech alternative software for wireless mouse keyboard. But no luck. For windows Logitech provides a software Setpoint to control such thing. Bad part is that Logitech do not provide Setpoint's linux verion

    The trackpad is treated as mouse device, so you should look at the pointer settings, not the keyboard one. The hardware reports very fine changes, but software (probably libinput / xf86-input-evdev) should interpret it. The pointer settings should allow you to control those properties and is exposed via a standard API, but the graphical user interface to control it varies between desktop environments.

Forget Solaar, you can do it natively (I'm on Xubuntu Core 18.04, but this apparently worked on Ubuntu 9.10 already). I have a Logitech K400 Pro which I transformed from a piece of junk into a working piece of junk w/

$ xinput

take note of the id of the pointer, not keyboard of your K400. Suppose it's 10, then

$ xinput --list-props 10

note interesting lines:

Coordinate Transformation Matrix (145): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
libinput Accel Speed (289): 0.000000
libinput Accel Speed Default (290): 0.000000
libinput Accel Profiles Available (291):    1, 1
libinput Accel Profile Enabled (292):   1, 0

increase sensitivity:

$ xinput --set-prop 10 289 1
$ xinput --set-prop 10 292 0 0
$ xinput --set-prop 10 145 2 0 0 0 4 0 0 0 2

I got to this page as I was trying to find a way to keep function keys as normal (and not their K400/r special functions which works in windows). Finally found it in Solaar, which has a "Swap Fx function" which should be turned to OFF

  • I tried Solaar on 20.04, but it does not show my K400r device.
