FGLRX controller reset laptop brightness on boot
So I installed the proprietary ATI drivers for my laptop and every time, before i log in, the screen goes to a 100% brightness, totally annoying, my FN keys works well, and the kde brightness properties works fine as far as i know.
So i googled and found i could change /sys/class/backlight/acpi_video0/max_brightness the problem is that every time i tried i got a permission error
i tried login as root https://help.ubuntu.com/community/Ro...root%20account same error don't know what ive done wrong.
the problem is before i log in so i suppose the video driver mess up my settings when it loads maybe there is a better solution for this...
Ill appreciate your responses.
