Is there a way to turn off light completely?

[AnimalOfArt]

Hello guys!

I'm getting eye problems when I'm looking into bluelight too long and I found no way to turn the light on the Voyage completely off in an official way.

Is it possible through a modified firmware to turn that light completely off?

Yes I should have done a better seach before, as this already was discussed. I apologize for my mistake and this won't happen again!!! This thread can be closed, as I managed to it with Frontlight master extension!

brightness 0:
echo 0 > /sys/class/backlight/max77696-bl/brightness

brightness 51:      
echo 51 > /sys/class/backlight/max77696-bl/brightness

brightness full: 
echo 239 > /sys/class/backlight/max77696-bl/brightness

python command
import os
os.popen("echo 0 > /sys/class/backlight/max77696-bl/brightness")
os.popen("echo 51 > /sys/class/backlight/max77696-bl/brightness")
os.popen("echo 239 > /sys/class/backlight/max77696-bl/brightness")

Thank you very much, but the KUAL extension Frontligh Master already did it for me!

But why?

To turn off the light.
The "mntroot rw" is not required, /sys tree is not part of the root file system, it is a (virtual) file system of its own.

The exact path (and sometimes the name) will vary with Kernel version, but will only appear and appear as writable if the Kernel supports that control knob.

Okay, but I already mentioned that the KULA extension "Frontlight Master" turned my light completely off, so I think I don't any further modification.

But nonetheless, thank you both for your help!!!

Oh no it's okay, I just thought you both were answering to me, so I responded to that. Sorry for misunderstanding.

I cannot see this multi-quote button. Maybe it's because of NoScript, although I whitelisted mobileread.com

( The multiquote button is the un-named icon to the right of "> QUOTE". It looks like papers, stacked up. Click as many posts as you want to multi-quote, then click "QUOTE" on the last one. OR, if you didn't know it was the last one and it's now too late, click "NEW REPLY" and all your quotes will be in there. )

I don't have this option either.

to the right of the [ > Quote] button is just the border of the page, there are no other buttons for me.

Not a big problem, you have to be logged in to post a quote anyway.
(Well, if you are not, the "quote" will offer to log you in, which can not happen with the multi-quote button - unless you can see it. )
