I can't get the brightness to adjust on my Acer 5740 laptop.
I am running Ubuntu 12.04 and Windows 7 in a dual boot.
I have searched and tried the workarounds using the edits to /etc/default/grub with no luck.
The best they do is restore my brightness to the last setting on a reboot.
My end goal is to get the Fn + left/right arrow keys working for the adjustment, but I will even settle for the brightness control in the System Settings to work. Right now nothing works in real time.
Can anyone help me?

Thanks,

Matt
