Cara mengatasi dekstop tidak mengingat "brightness level" di ubuntu 11.10

Jika kamu menginstal linux 11.10, mungkin kamu diresahkan dengan dekstop yang tidak mengingat brightness level setelah merestart kompi. Akibatnya kamu harus mensetting manual setiap menggunakan linux terbaru ini. Wah... bisa repotkan!! hehe tapi jangan kuatir. Nih aku kasih solusinya :)

Langkahnya:

1. Buka terminal

2. Ketikkan "sudo gedit /etc/rc.local"

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

exit 0

3. Edit file tersebut dengan menambahkan echo 0 >/sys/class/backlight/acpi_video0/brightness

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
echo 0 > /sys/class/backlight/acpi_video0/brightness
exit 0

4. Save file tersebut Semoga itu bisa membantu ;) 

Catatan: Untuk mengganti brighness level ubah ech0. Misal, echo1>/sys/class/backlight/acpi_video0/brightness
