[Pkg-acpi-devel] Bug#560702: Brightness keys do not work on Thinkpad X301 with kernel 2.6.30

[Christopher Desjardins]

Hi Ted,
Thanks for the quick response. Running ./kacpimon as root I get:

debian:/home/lontra/Desktop/kacpimon# ./kacpimon
Kernel ACPI Event Monitor...

When I press the brightness keys w/o the function key held down I get:

Input Layer:  Type: 4  Code: 4  Value: 199

However, when I hold down Fn+Home or Fn+End I get no response.  I do get
response from holding down Fn+<other thinkpad keys>. This is the same thing
with xev.

Regarding your acpi-netlink ... is that a package I should install? Should I
run kacpimon w/ the 2.6.26 and report those values to this report?

Thanks again for the spending response I really appreciate it!
Chris
