On the previous versions the default screen brightness was perfect for me but on 11.10 the default brightness is killing my eye.

I have changed the brightness like this level

but after restarting and every login/logout it returns to default 100%.

It was a bug on 11.10 kernel 3.0.0-12-generic and i was reported on lunchpad

https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/875061

and another report i linked on

https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/870805

As they suggested and when 3.1 released i have installed it, after that i never faced this problem. Currently i'm on kernel 3.1.0-030100-generic

Maybe you can try Ishans Python script: http://blog.ishans.info/2011/09/25/set-brightness-automatically-at-the-startup-in-linux/

This stores the current brighness-Information until the next boot.

From Ubuntu 10.04 to 11.10 I can not change my screen brightness. I use an Acer laptop with VGA Intel HD graphic 3000, and I think this is because my laptop (I tried to update BIOS two or three times so I think that make problems)

I must use xbrightness to fix my problem. You can try to install this package.

It requires some packages like: xutils-dev, libxxf86vm-dev, libxaw7-dev. After installation finish. You can change the brightness by run for example:

$ xbrightness 50000

You can read more on the man page or home site of xbrightness.

You can use this program while waiting for the bug fixed.
