Inspiron Brightness Working

I just did this, works nicely on my 1501.

Code:

sudo gedit /etc/acpi/video_brightnessup.sh

Replace everything in the file with this:

Code:

#!/bin/bash

CURRENT=$(grep "current:" /proc/acpi/video/VGA/LCD/brightness |awk '{print $2}')


case "$CURRENT" in

100)
echo -n 100 > /proc/acpi/video/VGA/LCD/brightness;
;;
87)
echo -n 100 > /proc/acpi/video/VGA/LCD/brightness;
;;
75)
echo -n 87 > /proc/acpi/video/VGA/LCD/brightness;
;;
62)
echo -n 75 > /proc/acpi/video/VGA/LCD/brightness;
;;
50)
echo -n 62 > /proc/acpi/video/VGA/LCD/brightness;
;;
37)
echo -n 50 > /proc/acpi/video/VGA/LCD/brightness;
;;
25)
echo -n 37 > /proc/acpi/video/VGA/LCD/brightness;
;;
12)
echo -n 25 > /proc/acpi/video/VGA/LCD/brightness;
;;
*)
echo -n 100 > /proc/acpi/video/VGA/LCD/brightness ;
;;
esac

Code:

sudo gedit /etc/acpi/video_brightnessdown.sh

Replace everything in the file with this:

Code:

#!/bin/bash

CURRENT=$(grep "current:" /proc/acpi/video/VGA/LCD/brightness |awk '{print $2}')


case "$CURRENT" in

12)
echo -n 12 > /proc/acpi/video/VGA/LCD/brightness;
;;
25)
echo -n 12 > /proc/acpi/video/VGA/LCD/brightness;
;;
37)
echo -n 25 > /proc/acpi/video/VGA/LCD/brightness;
;;
50)
echo -n 37 > /proc/acpi/video/VGA/LCD/brightness;
;;
62)
echo -n 50 > /proc/acpi/video/VGA/LCD/brightness;
;;
75)
echo -n 62 > /proc/acpi/video/VGA/LCD/brightness;
;;
87)
echo -n 75 > /proc/acpi/video/VGA/LCD/brightness;
;;
100)
echo -n 87 > /proc/acpi/video/VGA/LCD/brightness;

Dang, you're making me want to install Ubuntu again. So let me get this straight: Fn+Arrow Up/Down controls the brightness as it would in Windows? No BIOS downgrading?

 

Ya, works perfectly.
The brightness applet doesn't work though

 

Great work, thanks for sharing this with us.
