I am affected by this too after upgrading to 13.10. It worked fine in 12.10 and 13.04.
Using function keys I get an OSD showing brightness level increasing/decreasing, but screen brightness does not change. This is on an Lenovo laptop running upgradet 13.10 with Intel Graphics using i915. Setting brightness with 'echo 350 > /sys/class/backlight/intel_backlight/brightness' does work for me. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1207487 Title: Brightness Controls work but brightness doesnt change To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1207487/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
