Comment 86 for bug 568611

I have posted a minor update to the kernel and gnome-power-manager packages in my PPA https://launchpad.net/~kamalmostafa/+archive/linux-kamal-mjgbacklight . Users who have installed the PPA already don't need to take any special action -- your system's "Update Manager" will take care of upgrading the PPA automatically. This note is just for your information.

The updated kernel incorporates the latest changes from the official Ubuntu Maverick kernel, but no new changes to the experimental intel_backlight mechanism.

The updated gnome-power-manager incorporates these minor improvements to the brightness-up/down keys functionality for Gnome desktops:
  - the brightness "steps" now consistently fall on 5% increments
  - the brightness-down key now limits the lowest selectable brightness to 5% (very dim) instead of 0% (completely dark)
