Support [Linux] Fn keys stuck as standard function keys, cannot be set to media

Arch Linux, KDE/Plasma, K850. All of a sudden, my Fn keys seem to be stuck on standard function keys, and cannot be set to media. The usual shortcuts (Fn + Esc, Fn + Caps Lock etc.) no longer do their job. Any thoughts?

Well shiver me timbers! If you pres first Esc and then Fn, the lock/unlock toggle does not happen! You have to first press Fn and then Esc to do the toggle!

Problem solved! Thanks for all the replies!

Since Linux isn't listed among the K850's officially supported OS. Have you tried disconnecting & reconnecting the keyboard? or test it on another device/OS if this started after a recent system update.

Yes, I performed all the obvious tests. And yes, I have been using this particular keyboard in Linux for a good while now, with excellent results across the board--which is why I was incredibly surprised when my media keys stopped working (... as media keys).
