Debian 6.0.5 has the same problem. I press Fn+F6 then brightness bar is decreasing, but screen brightness is not decreasing. It alwasy stays at full brightness. I press Fn+F7 then brightness bar is increasing, but screen brightness is still full brightness.
We can do a test System -> Preferences -> Power Management -> On AC Power (see attachment) ** Attachment added: "brightness adjust test" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/996145/+attachment/3298904/+files/gpm-prefs-ac.png.en.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/996145 Title: Ubuntu 12.4 64 bits on Toshiba C665 (Nvidia Card) too bright To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/996145/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
