Hi i tried to change the green LED brightness with a: “sudo nano /sys/class/leds/green_led/max_brightness” I changed to 50. But i can’t save the file, it is telling me, i don’t have a permission to change this file. And is this a good way to change LEDs brightness? Thanks.
alt+f1 then log in as root//bananapi then its possible to change sys class values. not avalable from Pi in X server, ive noticed it when I tryed to change sys classes aswell
don’t forget to logout from root terminal then alt+f7 to go back to X server. hope it helped.
i am root, you think i am stupid? I haven’t any x server, because i have Ubuntu 16.04 server without GUI. I control my BananaPi from SSH.
How shuld I know? then write
sudo su to get a full root shell if that wont work then I cant help
To the OP. If you wouldnt be ao aggressive and a little more scientific on a Technology related forum, you probably would get an answer to your problem.
