How to use volume keys on Asus X54C?


Hi all,

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
lilo.conf: http://pastebin.com/7RRMFcM8

Any thoughts?

My Vaio is different from your Asus but give this a go, it (might) work-

Quote:
Fn + F3 to turn the volume down and
Fn + F4 to turn the volume up.
Reading the kernel config; not good with that yet; sorry-

That doesn't work.

I feel relatively sure that this is a kernel config issue. I have another Asus machine which is a netbook. When I had Arch, Debian and Fedora on that netbook, I could use xev to detect the volume keys. When I had CRUX on it, I couldn't. The main difference was that on CRUX, I configured and compiled the kernel myself from scratch. I think something similar is going on here. I just need to figure out what kernel options will allow me to use those keys.

Sorry that didn't work-

I looked and the only thing I found remotely close to kernel configuration was this linuxtopia page-
http://www.linuxtopia.org/online_boo...tion/ch09.html

Maybe this Linux Kernel book will help if you can find it online-
I would think that instructions on how to configure the kernel for volume control would be in there.
http://www.kroah.com/lkn/

Other than that I looked through 3-5 pages of Google searches and the alsa doc's related to the kernel archives. Here's the search I tried: 'how to configure kernel for volume control'
https://www.google.com/#hl=en&gs_rn=...0&bih=736&bs=1

Free linux books are in my signature line-
