My laptop Dell studio 1555 has Ubuntu 11.10. At every boot I have to set the brightness level as it gets reset to 100%. Could you please help me out to find a way not to change it every time? Thank you!
I have found that disabling the "Varibright" option under power management in the AMD Control Center fixes the brightness problem. I've never really measured what effect turning it off has on batter life, but I still get great battery life so I'm thinking the effect is minimal.
