My Toshiba C800 laptop (12.04lts desktop) has special function keys as follows:
F5-TOUCH PAD on/off
F6 to F11 (media player keys) work correctly, but the keys from F2 to F5 and F12 are not working.
Why would some function keys work, but not others?
I recently switched to KDE, and everthing is working fine except for the volume buttons, mute, ffw/rw, and pause/play keys. They're on the function keys, and normally you have to hold down another "fn" key at the bottom to use the function key. Thesee keys are the only way to control volume and mute. I am running Kubuntu 11.10 64bit.
