Ctrl keys don't work, need to debug hardware or software

Neither of the ctrl keys work. I have a Lenovo Yoga 13 with OpenSUSE 15, and have set the BIOS to switch the left ctrl with Fn. In that case the left ctrl (now mapped to Fn) works.



I get nothing on showkey -k on tty1.



How do I make sure if it's a hardware issue or software?

          You can run xev command and check keysyms/keycodes output.



          Little white box will popup, press Ctrl and check the output.

          • xev doesn't give anything either. And I think (?) showkey is at the kernel level, so should be a better check for hw problems.

          • How about trying some other distro Live CD, and check if Ctrl is working that way? If it doesn't, it might be hardware issue.
