Step-by-step fix
- Reconnect the keyboard: replug USB (try another port), or re-pair Bluetooth. For a laptop, restart Linux.
- Run the CheckMyMic keyboard test and press each key — any that won't light up is the problem key.
- Clean under a stuck or unresponsive key with compressed air.
- Check your keyboard layout/language is correct in Linux settings, and turn off Filter/Sticky Keys.
- Update or reinstall the keyboard driver, then restart.
Frequently asked questions
Some keys don't work on Linux — is it broken?
Run the keyboard test and press the dead keys. If they never light up across the test, the keys (or the keyboard) are faulty; if they work in the test, it's an app or layout issue.
My keyboard types the wrong characters on Linux.
That's a layout/language mismatch. Change the input language in Linux settings to match your keyboard.
