Ambient Light Sensor Not Working! Now To Disable?

When i am using the n810 it keeps making the screen go bright and dark and its annoying i am much happier setting the brightness on my own!

Can i turn off the light sensor so it does not effect the screen brightness and make it so the backlight on the keyboard stays permanently on?

thanks

can you tell me now to edit /etc/mce/mce.ini
i have got root but i dont know the command to edit it.

Re: Ambient Light Sensor Not Working! Now To Disable?

Install leafpad text editor.
Or emelfm2 file manager that can edit files.
Both can be called from the command line.
( Much easier than vi(m).)

Probably easiest for you to implement the method in comment #1 from the aforementioned bug:

Code:

sudo gaintroot

cd /usr/lib/mce/modules

mv libfilter-brightness-als.so libfilter-brightness-als.so.bak

sync

reboot

I'd suggest you learn the basics of vi as you'll never be stuck if you know vi... :)

If you want to try the method in comment #2 & #3, follow these instructions:

Code:

sudo gainroot

cp /etc/mce/mce.ini /etc/mce/mce.ini.bak

vi /etc/mce/mce.ini

Once in vi, enter the following commands (note - vi is case sensitive, so turn your caps lock OFF. If you make a mistake quit by pressing escape then colon, q and exclamation mark - <ESC>:q!<RETURN>)

Note: <RETURN> means press return key!

Code:

:%s/filter-brightness-als;//g<RETURN>

:x<RETURN>

Finally

Code:

reboot

If you're not comfortable with using vi, try this method - it's easier and will achieve the same effect as editing the file but without requiring a text editor...

Code:

sudo gainroot

cd /etc/mce

cp mce.ini mce.ini.bak

cat /etc/mce/mce.ini.bak | sed "s/filter-brightness-als;//g" > mce.ini

reboot

/etc/init.d/mce restart is faster. :)

*whistles* I made the light sensor only affect my keyboard light thanks to some leaked source *whistles*

Re: Ambient Light Sensor Not Working! Now To Disable?

Thanks qwerty! :)

@MicroChip123 - I know the ambient light sensor is located in the worst place possible - hopefully the Nokia designers have learned their lesson and won't repeat it on future devices - but try not to cover it with your thumb, that could well be why the screen constantly changes in brightness! :)

It's an alternative to rebooting the entire device - just restart the mce process instead.

Edit: If you mean qwerty's comment in small text... only he has the answer :)
