Last modified: 2012-11-14 11:33:27 EST
Description of problem:
Can't change brightness on netbook Acer Aspire One 521.
Is there a specific kernel this doesn't work with?
Did a previous kernel work?
Is there anything in dmesg when you try to adjust brightness?
What does /sys/class/backlight contain?
We need as many details as possible to even begin working on this and your bug report is sorely lacking.

I tried 3.2.2 and 3.2.1 kernels without any success.
