turn off keyboard backlight?

i tried to search but cant find any good solutionabout this,
how do you turn off the backlight of the keyboard manually? with my delicate fingers i can actually type in tp2 using my fingers, however in a decent light condition, the keyboard backlight automatically turns on sometimes and i cant read the characters on the keyboard (wished the buttons are black)
i tried to turn off the kb backlight autosensor, turns out it manually turns on the backlight, not turning it off.
any ideas?

I would also like to know how to shut off the keyboard back light.
I think it is a waste of battery life sometimes.
Do anyone know how to create some kind of manual switch that would allow me to toggle between having it on (with the auto sensor) and just always off?
I remember having some kind of application for this on my palm centro.
Thanks

Anyone?
The only work around I have found so far is to open the keyboard, then press the power button then press it again, and not touch the keyboard, and the back light will remaind off. I do this so I can watch videos with the keyboard out and the screen tilted.

you can change the timeout in hkcu\controlpanel\backlight\qkeyledtimeout default is 10. maybe you can change it to 0 or atleast 1.
it looks like keylightautosensor might be what you are looking for. you can try em out. soft reset to apply.

That didn't seem to do anything?

Does anyone knows how to do that??

Dim Soft Keys

Anyone know an easy way to dim the Dinc Soft, Capacitive Keys? I've searched around and haven't found a solution. Most apps seem to only be able to turn off the backlight on the soft keys....not dim them.

That is because they only recognize 1s and 0s (on and off, they're a switch, not a dimmer).

Damn....cause the Dinc's backlight on those Soft Keys is pretty damn bright. Wish I could fix this. For now, I just disabled the backlight...

You need to use a script in the init.d folder if your rom supports it. If not you need to use an app like script manager to run it at every boot. This is the script for the incredible, not sure if the path is the same for the aria.
Code:
#!/system/bin/sh
sleep 10
chmod 0666 /sys/devices/platform/leds-gpio/leds/button-backlight/brightness
echo "0" > /sys/devices/platform/leds-gpio/leds/button-backlight/brightness
chmod 0444 /sys/devices/platform/leds-gpio/leds/button-backlight/brightness

All you need to do is download an app called "screen filter." Launch the app, and then you may have to tap on the notification. Then, you can turn your led buttons off pretty well (they may light as soon as you turn screen on, but that's it.) This app is great. You can also using it during the night, when you're texting under the sheets, or when you want to save your battery, because you can make your screen darker than you can from your phone's settings. Please be careful though, do not set the brightness too low! hope this helps!

[Q] HTC One X Maximus v4.2 dim capacitive leds to 1

Hello,
i'm trying to dim capacitive buttons because for my taste they are way too bright.
In /sys/class/leds/button-backlight/ which file should I edit?
Editing brightness i can turn then on or off, but i want them on, but on dimmiest mode.
Editing currents i can turn then on or off, but i want them on, but on dimmiest mode.
Editing max_brightness does nothing.
The only file that makes me happy and dims leds, by editing lut_cofficient, setting to 1. This way leds are barely lit.
But on screen off or reboot it restores back to original setting.
What sould I do to make them stay dim?
I have been searching for a while, but I go nowhere.
Thank You!

you can write a .sh script and set it to start at boot
or use tasker($6) to make your own app
lut_coefficient seems to control the brightness properly :S

+1 for tasker.
I don't know how this app hasn't recieved more coverage.
This app is one of the best, most useful and functional apps there is.

I would like to go that script way. How do I create a script? Is there a tutorial how to create a script?
echo 1 > /sys/class/leds/button-backlight/lut_cofficient

i dont think its possible to do this with a script, as the lut_coefficient resets to 100% on Screen-OFF and screen-ON,
you have to make your own app
or find a really good script manager
or make a script that keeps your phone awake and kill your battery in 1 hour
EDIT: it wouldn't take you more than 15 mins to make the app in tasker (7 days trial)

Another Idea for you, you can use Screen Filter app
to turn soft-key's backlighting off.
I use it when I read at night, it works great

here i made you an app(requires root) you can post on your home screen
hxxp://dl.dropbox.com/u/102990830/Low_Light.apk
i find it a bit difficult to make it run automatically when screen turns on

That's a great workaround. Thank you.
I still hope, that someone will make proper permament method for that diming capacitive buttons.

Screen filter is great, but I need something that only dims the buttons, not to turn then off.

Ok managed to make another one (delete old one) , this one sets lut_coefficient to 1 when device starts and when screen turns on. I think HTC will fix this thing in coming JB update.
Here's the link:Low_Button_Backlight.4.apk
Don't forget to press thanks for my 15 mins effort

This is program is better, but still not perfect. Lut_coefficient comes back to original state if there is bright enought and system decides to turn lights off and when it switches back on it will be in its original state.
Maybe it is somehow possible to prevent system from diting that file?

[ION] Totally disable auto-brightness on Stock ROM?

Hi, guys.
As you'll already know, Xperia Ion Stock ROMs have no auto-brightness toggle on settings, apparently. And even if you use a 3rd party app to fix the brightness at a value, it keeps blinking around that value according to light sensor.
Light sensor has always been told to be such a battery-drainer, so here's my doubt:
Would it be possible to create a mod, app, flashable ZIP or something to disable that auto brightness feature at all?
Thanks in advance.

Lol? Light Sensor isn't battery drainer. You have wrong informations.
Sent from my LT26i using xda developers-app

Light sensor constantly reads an input, that obviusly uses a substantial amount of battery.
Anyway, is there any toggle solution?

If you want to really disable it, try this -
0. MAKE A NANDROID BACKUP (VERY IMP)
1. Use a root file manager and go to /system/etc
2. Open hw_config.sh
3. Search for this line - echo 1 > $dev/lcd-backlight/als/enable
4. Change 1 to 0, then save and reboot
5. Hopefully it should disable als now.

Thanks for the method! But wouldn't that disable brightness at all? I want brightness on, but light sensor-based automatic brightness disabled.
Greetings.

No no, you can adjust brightness in settings. It only disables the ALS sensor(Ambient Light Sensor). I have tested it myself.

[Q][CM10.2] Display not turn on backlight keys, how?

as for the display do not turn on the backlight of capacitive buttons? I want that only light up when I touch only the capacitive keys?

And why don't you ask on CM thread?don't you think it's more logical you will get an answer there,rather than here?
Not to mention you were not clear what your problem is.

I know that cm does not have that option, and because stock lg firmware is avaliable...
I want to know if there is a way to not turn the backlights on the keys when you touch the screen in CM10.2 or 10.1
but only when touch the screen, i want backlight when touch the keys.

Why not disable the brightness.. There's an app "capacitive buttons" on playstore so you can switch on/off ur capactive lights.. Just reboot phone to go back to default settings

Any news about that?
Actually we want the behavior of capacitive buttons to be like in the stock rom
To flash only when we touch them and not all the time regardless if we touch them or not

I found a way to disable the light permanently
su
cd /sys/devices/platform/leds-pm8058/leds/button-backlight-portrait
echo 0 > brightness
chmod 444 brightness
cd /sys/devices/platform/leds-pm8058/leds/button-backlight-landscape
echo 0 > brightness
chmod 444 brightness
