Comment 10 for bug 314119

Hi akromic,

I am not a maintainer and am not sure about the justifications, but I also reported a bug regarding brightness controls not working which was marked as a duplicate of #311716. Buried among the many comments of that bug are suggestions that it be renamed something more general like "problems with brightness after kernel update" rather than the misleading name regarding inverted brightness, so I would surmise that both problems are related to the same changes in the kernel and will be fixed by the same patch.

Following the suggestions in comments on that bug, I was able to work around the brightness controls not working on my Lenovo X61s by adding the following to /etc/modprobe.d/options:

options thinkpad_acpi brightness_enable=1
