For Jaunty, my current workaround to get max brightness easily is to add a
launcher in my menu bar.
The command is :
sudo /usr/local/sbin/max-brightness
The content of this script is :
#!/bin/sh
FILE=/proc/acpi/video/VGA/LCDD/brightness
MAX=`/usr/bin/awk '/^levels/ {print $NF}' $FILE`
echo $MAX > $FILE
This file needs to be executable (chmod +x /usr/local/sbin/max-
brightness). To make sure the user is not prompted for password every
time it runs this script you can use "sudo visudo" to add the following
lines :
# Brightness fix
NAME_OF_USER ALL=NOPASSWD: /usr/local/sbin/max-brightness
