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