Public bug reported: I have recently updated from 12.04 LTS to 12.10 to enable better support for UEFI booting on my machine.
Now that I have updated to 12.10 the brightness controls no longer work. They were working fine in Version 12.04 LTS. I have been debugging this problem with a very helpful person (Toz) on the Ubuntu Forums and it would be worth taking a look at this thread to see progress to date http://ubuntuforums.org/showthread.php?t=2092897 As suggested I have created a bug report with "ubuntu-bug linux" in terminal. I am happy to provide any additional information they may help resolve this problem. Regards, Dave.
