Laptop not work anymore

Yesterday I downloaded and installed arduino-1.8.8-linux64.tar.xz on my Kubuntu laptop. Installation went without any problems BUT after the installation I found out that my keyboard didn’t work properly anymore. Was able to use Putty from my Windows PC and removed Arduino again, unfortunately this didn’t solve the problem as the keyboard still doesn’t work properly.

Arduino does not do anything to keyboard drivers.

I think this is an issue better suited to a Linux tech help forum.
