Macbook Pro late 2011 screen brightness issue
- by buchzumlesen
The keys to set the screen brightness work properly but everytime I reboot, the screen brightness is reverted to 100%, which is very annoying.
I've already tried to add the following lines to /etc/rc.local but with no success (only the keyboard backlight stays off):
#!/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 '1' > /sys/devices/platform/applesmc.768/leds/smc::kbd_backlight/brightness
echo '6' > /sys/class/backlight/acpi_video0/brightness
rfkill block bluetooth
exit 0`
This worked for me when I was using Ubuntu 12.04 and also did after the upgrade to 12.10 but then after rebooting the screen brightness always reverted to 100%.
Would be nice if anyone knows how to fix this.

Thanks in advance!
