x120e + Fedora 16 LXDE unable to adjust backlight, battery monitor not working

Hello, I have a Lenovo x120e, running Fedora 16 LXDE. I'm using Fedora's default open-source ATI driver. I have the latest updates installed as of today and cannot get the backlight to work or lxpanel battery monitor to work.

I have tried:
 yum reinstall bash
From here
I cannot use an older kernel because this is a fresh install and I have no intention of using an older kernel from koji unless there is absolutely no other way. (The kernel confirmed to work with this is from Dec 2011 :O)

 xbacklight -80
Which ends up telling me I don't have a display that I can turn the brightness down of.

I've looked inside /etc/shells with nano and everything looks in order (the
 yum reinstall bash
must have worked just fine.

I've looked at this as well already. My problem is, the backlight adjustment never really worked, orginal or latest kernel.

The battery monitor on the lxpanel doesn't actually work. Keeps telling me it's at 100%. Haven't had time to figure out why, but there a terminal option for this? (arguebly not all that important).

Hi, I have an laptop running with Fedora 16 Lxde too. To solve this, I make a script which control backlight.

You can download my script at < > (my website about Math).

If you open a terminal in the folder which you unzipped the '', as root, try this:

bash slight s 1 ---> to screen more dark

bash slight s 6 ---> to screen more bright, or any number between 0 and 7.

Together 'slight' is the 'mybattery' shell script.

The syntax is:

bash mybattery (don't need root)

If you want, open my scripts in a editor like gedit, vi, etc and you will understand how them work.
