I updated the kernel to 2.6.34-020634rc6-generic and the voila, the function keys to change brightness works fine.
Issue with 5 being the least brightness is not yet resolved. Let me know if there is any workaround. When the system is on battery, the brightness reduced automatically to half (5) which is least for me, and when I become idle the brightness is reduced to (0) which is highest for me (problem) Thanks for 2.6.34-020634rc6-generic work -- [Karmic & Lucid Beta 1] Brightness fn keys lost functionality (Lenovo laptops) https://bugs.launchpad.net/bugs/406515 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
