Brightness shortcut doesn't work right on an Acer Aspire 5750G

I have an Acer Aspire 5750G with Ubuntu 12.10.

I have a problem with the brightness shortcut. If I press Fn+Right Arrowand Fn+Left Arrow, the brightness actually changes but not in the right way. On the other hand, when I type in the terminal gnome-control-center screen, I can adjust the brightness in the proper way.

Is it possible to adjust the brightness of the laptop in the right way using the shortcut?

Remark: I found a lot of questions on AskUbuntu regarding brightness issues but here the problem is different; both "Brightness and Lock" and shortcuts work right now, but shortcuts do not work in the right way!

Problem solved:

I finally discovered that using the shortcut would have had the effect of XF86MonBrightnessUp or XF86MonBrightnessDown while the effect I want is given by replacing those commands in the shortcuts with xbacklight +10% and xbacklight -10%.

Of course one has to install xbacklight just typing in the terminal:
sudo apt-get install xbacklight

I don't know if there are smarter solutions to the problem but this one satisfies me.
