How to turn off leds on cubietruck?

Try this, it should work with the legacy kernel (not sure though):

see available leds
$ ls /sys/class/leds/
see available options for eg blue led
$ cat /sys/class/leds/blue\:ph21\:led1/trigger
Then turn off eg blue led:
# echo none > /sys/class/leds/blue\:ph21\:led1/trigger

If you need to turn leds off after reboot, put it in an executable script and run the script @reboot in root crontab

There are also other options if you do not want the leds to turn on at boot.
