solaar and logitech k830

[R C]

Hello,


I am running Ubuntu 
(ubuntu-24.04.1-preinstalled-desktop-arm64+raspi.img)  on a raspberry 
PI,   and use solaar for using both a logotech mouse and a a keyborad K830.


The keyboard works, but the  mousepad of the keyboard doesn't.   Am I 
missing something?


Ron
