Having the same issues with a MacBookPro 4.1. Have tried the suggested commands but the brightness doesn't change. I can change the brightness during login and during the first +-10 seconds after login. After this the birghtness is fixed until reboot. Suspending the machine results in maximum brightness and still no control.
The apple_bl module is loaded and reloading the module also doesn't solve the issue. Previous versions of ubuntu didn't have this problem -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1006453 Title: Screen brightness is not affected by keys ("MacBook Pro") To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1006453/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
