I cannot make the media keys (play/pause, next etc) work with Amarok. Ive changed the shortcuts for those in the shortcuts part of Amarok and they still wont work. Has anyone else had this problem? I have the lcd working with the G15 Amarok Plugin Plus plugin. The keys work in Rhythm Box.

Check this, though german, you should understand it. If not, reply again.

um sorry for the late reply but I still dont understand what to do?

Install the package xbindkeys
...I guess you already have the g15daemon installed? If not, try to google it or search in g15forums.com to get a tutorial
Edit the file .xbindkeyssrc

Of course only the coded part.
