I mainly use my netbook for writing and browsing. So I have set the brightness to a minimum level. Sometimes when I watch videos I increase the brightness using hotkeys. But when increased after few seconds it reverts back to the default level I have set. Is there any way in which the brightness level I have set using hotkeys can be retained untill the machine is shutdown?

are you on battery power? – RolandiXor Nov 14 '10 at 2:01
please add the model and manufacturer details, to check if its a problem that many others are facing. – theTuxRacer Nov 14 '10 at 3:06

check the brightness section at the end on launchpad. Its for a Acer Aspire. Googling tells that only some of Dells, Acers and Toshibas have that problem.
