Xubuntu 12.10 does not save screen brightness
my Xubuntu does not save the setup of the screen brightness.
I already check on Internet for such problem.
I did the following actions but it does not work at all.
In file /etc/acpi/save-brightness.sh I put the following :
cat /sys/class/backlight/acpi_video0/brightness > /etc/acpi/brightness
sudo chmod +x /etc/acpi/save-brightness.sh
sudo ln -s ../acpi/save-brightness.sh K99-save-brightness
Do same in the /etc/rc6.d directory
cat /etc/acpi/brightness > /sys/class/backlight/acpi_video0/brightness
