[SOLVED] automate terminal command, netbook brightness

[minties]

Hi all. I am using Mint 13 Maya 64 bit.

I am not able to lower the brightness on my Acer Aspire One netbook via the function keys, which work in Windows.

So every time I boot into Mint, I have to open a terminal and execute: sudo setpci -s "00:02.0" F4.B=40 (40 is my preferred level of brightness, lower value to reduce brightness and vice versa)

Anyway, how can I automate this command, so that it is executed as soon as Mint loads? I can open up a terminal and press the up arrow, which displays a history of the last commands that were executed, which saves me from having to type it all out every time. But I would like it all to be automated so that I don't have to manually set the brightness in the terminal.

Is there a way of editing some startup file, or create some sort of script? Thanks in advance.

Open a terminal and execute the following command:

Code: Select all

sudo gedit /etc/rc.local

Just above the line that says "exit 0" add the following:

Code: Select all

sudo setpci -s "00:02.0" F4.B=40

Save and restart.

Thanks! You solved a very annoying problem!

Anyway, I'm wondering how to set brightness using the FN keys on my laptop's keyboard: unfortunately they don't work for me on mint.
What do you think I could do about it?

Thanks a lot
