Comment 5 for bug 1080552

One idea could be to save the settings to the user's Home directory when logging out. For instance, run a script when the user logs out. The next time they log in, the computer runs the script and sets the user's specified brightness.

For instance, about the time the user logs out, a script reads from /sys/class/backlight/<foo_backlight>/brightness and saves it to a file. Then, when the user logs back in, the system reads that brightness number and writes it to /sys/class/backlight/<foo_backlight>/brightness.

It's not a permanent fix but it seems light a good work-around.
