This looks more like a gnome-power-manager aspect. When you log in as a user (and I suspect the login screen counts as a user) it restores the last configured brightness settings.

If you have more information that pinpoints this bug to X rather than gpm, please feel free to elaborate and reassign it back.

affects: xserver-xorg-video-nouveau (Ubuntu) → gnome-power-manager (Ubuntu)

Thanks for the report, it has been some time without any response or feedback in this bug report and we are wondering if this is still an issue for you with the latest release of Ubuntu the Natty Narwhal, May you please test with that version and comment back if you're still having or not the issue? Please have a look at http://www.ubuntu.com/download to know how to install that version.Thanks in advance and sorry for the late response.

Changed in gnome-power-manager (Ubuntu):
importance: Undecided → Low
status: New → Incomplete
