Comment 68 for bug 415023

#65, getting g-p-m not to react to key presses would be an improvement, but for me at least (and I'm guessing everyone else with this bug?) the screen flickers in the GDM login screen, before I press any brightness keys or attempt to control the brightness at all. So the problem seems to me to be more fundamental than just how the system reacts to keystrokes. I think it's just how g-p-m rounds the numbers for the brightness values.
