Extended Brightness Settings
 

I think I read somewhere that the 770 actually has more than 100 "steps" of brightness, and the brightness applet/widget on the main screen maps to some of these.

I would actually like a DIMMER display than the dimmest available one available in the applet for reading at night. Does anyone know how to change these settings or can point me to a link?

I remember reading this, but I don't remember where it was...

Thanks

You need to load or flash modified kernel. Then you may use blset script to set the brightness from shell. You can even put it to some startup script to set all levels to custom values.

Recently I found there may be some reason why the default lowest setting is so bright. When set below this the screen blinks when connected to charger (at least in latest firmware, never noticed before). Also the absolute lowest setting occasionally blinks too (caused by wi-fi?). It is probably harmless but might scare people so maybe they played it safe and set it to brighter level when it is not visible.

Thanks Fanoush... yours was the web site I ran across some time ago and have been trying to find again. This will be a great improvement for me in using it as an e-book reader in the dark. I don't have the WIFI/charger on when I'm reading, so the flashing hopefully won't be an issue.

Actually,

Fanoush, after reading your website, it appears as though you can set the brightness from the command-line without the extended kernel for hardware level "8" by using:

echo 1 > /sys/devices/platform/omapfb/panel/backlight_level

That MAY be low enough for me, but the issue I'm having is that after you issue the command, it is reset a couple of seconds later back to whatever the brightness widget currently is set to.

Is the only way around this to set up the tables as necessary, or do you happen to know the process responsible for resetting the brightness level? Perhaps killing this process?

I didn't find any other way. There is no source for brightness applet or dsme daemon so only Nokia can change it. And when you kill dsme which is responsible for this the device reboots.

As the brightness keeps resetting the indirect table is the solution. It is still reseting but to the value you can set in the table.
