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
Does it work in the login screen?
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.
