I do have a wireless Logitech K750 keyboard (silver Mac version) connected to a Lenovo ThinkPad (via the unifying USB receiver, together with a wireless Logitech mouse M705) and currently running Ubuntu 12.04.
By default the F-keys are mapped as multimedia/function keys, e.g. Play /Pause. As I don't use them very often, I want the F-keys to behave like the "real" F-keys (F1–F12). How can I do that?
I know there is an option in the BIOS settings, but this only toggles the built-in keyboard of the notebook, not on my wireless keyboard.
I know there is a way to change this for the Apple wireless keyboard (AppleKeyboard#Change_Function_Key_behavior), but there is no "parameters" directory in /sys/module/hid_logitech_dj/.
Any ideas? Or is there maybe a way to do this in a later Ubuntu version (13.04)?

Thanks a lot for your help Lekensteyn. Finally Solaar works just fine. In the "Known Issues" of Solaar it says that it does not work with the Nano Receiver. But I have one and it works just fine. Just don't forget to read the installation instructions and run the
rules.d/install.sh script. It also recognized my M705 Mouse.
