I wish to turn off my keyboard backlight, and I have discovered the files kbd_backlight
and kbd_backlight_timeout
in /sys/devices/platform/sony-laptop
. Both say '-1' when opened in gedit. What values can I change these text files to, what do these values mean, and where do you go to learn such information?
A comment below indicates values for these files are listed in this answer.
-1
is not given in it, then you'll have to read the code to see what happens when it's -1.
