Keyboard doesn't do anything in Kodi. Should I do something in settings to activate the keyboard?
In case someone else has this problem, here is the solution: Some keyboards are being detected as joystick in linux.
My keyboard A4Tech G800V is one of them.
As GDPR-2 said (then removed?) in his post, I had to make a udev rule to prevent my keyboard being detected as a joystick.
1. Downloaded 51-these-are-not-joysticks.rules file from GitHub - denilsonsa/udev-joystick-blacklist: Fix for keyboard/mouse/tablet being detected as joystick in Linux
2. Copy to /etc/udev/rules.d/51-these-are-not-joysticks.rules
3. Reboot
