Hello Pop Os. I have installed the latest plasma desktop, and now the numberpad on my keyboard does not work (I have toggled keypad lock on an off). I have tried several keyboards an they all have the same problem . The same keyboards I have used on my linux mint and my debian computers
Have you followed the instructions that can be found in the official support pages to install Plasma? Installing a different DE in Pop (or any other distro that comes with a DE preinstalled) isn’t so simple. You may want to test if the problem persists if you login with a brand new user, if not then it means that something in ~/.config is probably broken.
