udah bisa nih gan skrg..
ijin share ya..
ini caranya :
edit file /etc/rc.local dengan ketik
sudo gedit /etc/rc.local
tampilan awalnya bysanya ky gni:
#!/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
sebelum exit 0 tambahin # jd #exit 0
soalnya klo ga gtu ga mau..
trus dibawahnya tambahin :
echo 2 > /sys/class/backlight/acpi_video0/brightness
jd ky gni :
#!/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
echo 2 > /sys/class/backlight/acpi_video0/brightness
oia, nilai echo dari 0 - 10, tkutnya 0 jd item jd coba aja 2 dlu..
save file trus exit.
trus tes deh, ketik di terminal:
echo 2 > /sys/class/backlight/acpi_video0/brightness
klo berubah jd minimum berarti berhasil!
note:
tp untuk laptop saya (Toshiba, proc n vga intel), pas bagian
echo 2 > /sys/class/backlight/acpi_video0/brightness
bukan acpi_video0 tapi intel_backlight
soalnya setting brightness di acpi_video0 ga ngaruh.
trs echo 2 diubah nilainya jadi echo 1593750 (nilai ini setengah dari max_brightness), jd buka dlu file max_brightness di folder intel_backlight buat ngeliat nilai max nya..
