Comment 39 for bug 451282

Gabe, is it possible to find out the source code that sets the values for brightness and actual_brightness and get them to agree after boot up?

It certainly would be better to try to fix it at the upstream source.

My limited knowledge of /sys/ directory is that it's mostly created by kernel drivers .. is there a way to get one of the kernel coders to just look at this bug and see if it could be in the kernel code? If so, then I'm sure linus would appreciate getting a bug filed.

If you decide to add a fix to /etc/rc.local (or some other script), one problem is that each different graphic card / driver seems to create the /sys/../brightness and /sys/../actual_brightness in different locations. To meet this issue, any script would have to search /sys/ first and then test and assign the appropriate values.

Keep in mind that doing this on boot wastes a bit of boot time (milliseconds), but that contradicts one of the goals of ubuntu to cut current boot times in half.

regards,
