I have Toshiba Satellite Pro laptop with ATI graphics card.
Recently installed Ubuntu 12.04 (64-bit)
I can adjust the screen brightness but after restarting the screen brightness resets to maximum.
Earlier I edited the /etc/rc.local file and added echo 2 > /usr/class....../brightnes
to set the brightness
but now since I installed the fglrx driver(graphics driver), the issue is back.
Now, no matter what brightness I set, after restart, it's always the maxmium value.
