I installed Ubuntu 12.10 with kernel version 3.5.0-18 on a Lenovo Thinkpad T530 and everything seems to work well except the brightness control. When using integrated graphics, it works fine, but if I switch to the Nvidia graphics, I only get the brightness notification like it's working, but the brightness doesn't actually change. I filed a bug here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1083984 I tried various different config tweaks as noted on Launchpad, and I also tried other newer kernel versions with no success. I was told to email this list to see if there were any suggestions.
