Hello, there is quite a big trouble around few specific keyboards that are not working in Linux. I personally have "Lenovo Professional Wireless Keyboard and Mouse Combo 4X30H56803" The keyboard is not working, mouse is. There is a lot of information spread across multiple threads of many sites. Issue is described quite well in many of them. - https://askubuntu.com/questions/897729/lenovo-professional-wireless-keyboard-and-mouse-combo-not-working-in-ubuntu?noredirect=1&lq=1 - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1771431 - https://bugzilla.kernel.org/show_bug.cgi?id=197787 - https://unix.stackexchange.com/questions/377830/linux-hid-driver-for-primax-wireless-keyboards/377873#377873 - https://forums.lenovo.com/t5/Linux-Discussion/Professional-Wireless-Keyboard-not-working-on-Linux/td-p/3726486 Could you please have a look at it?
