After installing ubuntu desktop edition on my hp laptop with vista in a dual boot configuration, I faced all these problems like configuring wireless on ubuntu with broadcom and then how to install my favorite twitter client – tweetdeck on ubuntu.
After solving all these problem I noticed a quite different problem which relates with the display of my laptop screen which goes dim or brightness decreases to a great level if I run ubuntu on bettery. But when I run ubuntu on charger it runs with approprite brightness.
After some play around in ubuntu I was able to fix the display brightness getting dim on battery, lets see how I fixed this problem
