I meets a problem that my laptop boots with full screen brightness and full keyboard backlight.

According to a post on Ubuntu forum for Macbook (http://ubuntuforums.org/showthread.php?t=1987790), it is possible to fix it by editing /etc/rc.local. However, it do not work on my ASUS Zenbook UX32VD. Moreover, I want to disable the touchpad by default.

Could you please tell me the methods to deal with these problems?

It works here. I've added chmod a+w /sys/class/backlight/acpi_video0/brightness to my rc.local and I can now do echo 1 > /sys/class/backlight/acpi_video0/brightness which works as expected.

  • I used "sudo" to change the permission to a+w and added like what you add. However, whatever what I try to add, the full screen brightness still exists. – Kin Feb 6 '14 at 16:51
