11th or 12th gen? Is this a new issue or was it an issue on day one with 22.10 for you?
Which F keys are not doing what specifically?
If you’re on 12th gen, applied the Grub parameter, functions not using the Fn key will work such as brightness, airplane mode, etc. If however, you’re talking about using Fn + F1 through F12, what is the result desired and keys pressed in this case?
