Fujitsu Lifebook S-4546

More e-mails about the Lifebook.  From Klaus Rudolph < lts-rudolph {at} gmx DOT de >, he was having problems with the FN key on the keyboard.

I found your website with your linux usage report for the lifebook. I have the same lifebook but can?t get the function keys to work.I can?t switch sound on/off or the screen brightness with the FN+Fx keys under linux. I installed a suse linux 8.2 with kernel 2.4.20. An older linux (suse 7.3, kernel 2.4.10) works well. Can you give me an idea where to search for. Is there any deamon to start? Any add on to install? I don?t touch my bios settings so I don?t have any idea :-(

I've never had a problem using the FN key to raise/lower the volume, and raise/lower the brightness of the LCD panel, it's always "Just Worked" ™ for me with no problems.  Subsequent e-mail said:

The problem comes up with using acpi by default in the actual kernel. With the parameter "acpi=off" at the grub prompt or in the /boot/grub/menu.lst the acpi switches off and the FN+Fx keys work again. 

So don't use current version of Linux ACPI drivers with theselaptops :). 

Werner Heuser < Werner.Heuser {at} web DOT de > has his own Lifebook S-4572 page, which links back to these pages.  Since I'm in the process of changing domains, I asked him to update his page to reflect my domain change.  He also has a website that deals with laptops and Unix at http://www.tuxmobil.org.
