I'm new with Linux and I have an issue that I have being researching and have not been able to find a solution so far. I was wondering if any help can be given. I have an Asus Q500A with Win-8 and Ubuntu 12.04 64 bit and Whenever i log-in to Ubuntu, it does so with full screen brightness and keyboard back-light at full . How do i get rid of this? How can I tweak the start-up setting for screen brightness and disable keyboard back-light at start-up?
Note: I already tried this and is not working.
Add this to /etc/rc.local
:
echo '2' > /sys/devices/pci0000:00/0000:00:02.0/backlight/acpi_video0/brightness
echo '0' > /sys/devices/platform/applesmc.768/leds/smc::kbd_backlight/brightness

To turn off the keyboard backlight on boot, you need to add this to
/etc/rc.local
:You have an Asus laptop but you input
applesmc.768
so it didn't work. For my case I added to/etc/rc.local
the following line:and it worked.
