Also Ted, would using your package solve this issue for me and if so how do I install it? As far as I can tell all I run is 'make' but where would I put the resulting module (is that the right word?)?<div><div></div>

<br>
Try running kacpimon and see if you get any events for the brightness keys at all.<br>

Package: acpid<br>
Version: 1.0.10-4<br>
<br>
I was running Lenny and needed to upgrade my kernel to 2.6.30 for my<br>
wireless card. However, after upgrading my kernel to 2.6.30 my<br>
brightness keys no longer worked. I was also unable to adjust the<br>
brightness with gnome-power-manager. I initially noticed the issue when<br>
upgrading the kernel and acpid from backports. I then reinstalled and<br>
upgraded to squeeze and used the acpid and kernel image from the testing<br>
repository and it had the same effect. <br>
Just for fun, I threw in a Ubuntu CD (9.10) to see if my brightness keys<br>
would work and they do. I am curious what Ubuntu does here that's<br>
different than Debian? I am curious if CONFIG_ACPI_PROC_EVENT is still<br>
disabled from the kernel?<br>
<br>
I also think that bug 521280 is similar to this report. However, that<br>
bug appears fixed and thus why I'm opening a new report.<br>
