I have an Asus G75VX laptop running Fedora 20.The laptop has a keyboard backlight that is turned on by default every time I log in, which is undesirable behavior.I tried to solve the problem by doing the following:Become root and use the chmod command to change the permissions on the /sys/class/leds/asus::kbd_backlight/brightness file, which contains the keyboard backlight brightness value, from 644 to 666.Add the following commands to my ~/.bash_profile:kbd_brightness_file=/sys/class/leds/asus::kbd_backlight/brightness if [[ -e $kbd_brightness_file ]]; then     echo 0 > $kbd_brightness_file fiI expect that when I log in, the .bash_profile will be run, and will write the appropriate value to the brightness file, thereby turning the keyboard backlight off.However, this does not work. Every time I restart my computer, the brightness file's permissions change back to 644!I wonder if the file is being re-created every time the computer restarts...
Permission of file keeps changing back
