I have CRUX on an Asus x54C. I would like to be able to use the volume keys on the laptop, but xev doesn't register them. The keys are Fn+F10, Fn+F11, and Fn+F12. xev registers F10, F11, and F12 on their own, but not with the Fn modifer added.
My Googling suggests I need to add 'acpi_osi=Linux' to my kernel line, and I have done this, but no dice.
Here is my kernel config: http://pastebin.com/qgwZizHJ
