This was a problem until nightly 4 I think. It doesn't work on the beta.

I was on 16 and it didn't work, then wiped and went to 17 and it still doesn't work.

That's strange. When you wiped, did you SBF or just do a simple wipe? I'd try SBFing back to .340 and then going back to the latest nightly. It honestly sounds like something in the framework for the display settings is corrupted or something. You shouldn't be having any FC issues changing the levels.

Thank you for this. Never had auto brightness.
One of the best fixes.

There is lots of information on the internet about cm brightness settings, so I'm not going to go into depth on all of them. This post is about my experiences with dx specific things. (Note: Auto brightness doesn't work in the beta. I can't remember which nightly got the patch.)

First, a quick explanation of what makes the cm auto brightness special:
On the front of your dx, there is what's called an ambient light sensor. This is used to measure the light shinning on the front of your device. On stock moto, the light sensor reports an intensity and there are about 4 different brightnesses that the system chooses based on the current value.

CM is a little different. CM takes the values and averages them over a period of time. ("Window length" in settings). Why is this awesome? Have you ever been in a place where the system keeps jumping back and forth between two different brightness levels? This can be extremely annoying! Averaging the values can help deal with this. Are there any disadvantages? Unfortunately, yes. The system react more slowly to sudden changes in light. Lucky for us, Team Douche thought about this and there are things we can to fix this. Setting the "Reset threshold" will let the system react quickly to massive changes in light.

DX Specific:
If you are like me, using your stock DX in the dark is like letting loose 1000 suns directly into your eyes. Well, fear the dark no longer! CM can help. Check "Use custom." Then, set "Screen dim level" to 2. (Note: In Nightly9, a value of 1 appears to turn the backlight completely off. Not recommended.) Next, tap "Edit other levels..." Here's my settings:

Note: In the left most column, the fourth level says "50." Change this to "65" for best results.

As you can see, the lowest setting is now 2 instead of the moto stock 20. YAY! I bet you wondering, "gpaulu, why do you have two levels with the same brightness value?" Don't worry, I'll get to that. :wink2:

Unfortunately, moto kind of screwed us on brightness reporting on the low end. The lowest reported value is 10. The next one up from that is 100. This sucks for indoors because the true level in my house is around 60 or so. This means that the sensor reports 10 and the brightness level is at 2 while the lights are on. :androidsad:
I found 3 different solutions to this problem. I will tell you the first two and why they suck. Then I shall wow you with my genius!

1) Set bottom brightness level to 20 and use manual brightness widget when the lights are out. *slap* This is a writeup about AUTO BRIGHTNESS, you fool!
2) Don't check "Allow light decrease." This means that the brightness level won't decrease until you turn off the screen. Acceptable solution, but it kind of sucks.
3) Use the settings in my screen shot, then check "Allow light decrease" and set "Decrease hysteresis" to 70% or higher. (I like 90%). Now, if your sensor level ever gets above 10, the brightness will never go back down to 2 until you turn the screen off again. Notice how in my screen shot, the sensor is at 10 and the brightness level is 25. :grin3:

tl;dr;

check "Enabled"
"Reset threshold" 1000lux
check "Use Custom"
<EDIT>
"Screen dim level" 2
Select "Edit other levels" menu. Select "Set number of levels" and change it to 8.
</EDIT>
Use screen shot^. Change 50 in left column to 65.
check "Allow light decrease"
"Decrease hysteresis" 90%

Hope that helps! Let me know if you make any improvements. :android-smile:

<EDIT>
Night mode is awesome for the dark, too! Use the FX widget.
</EDIT>

After applying the following settings and unchecking auto brightness my screen setting says disabled where your says 25. Am i doing something wrong?

You want to check auto brightness in display settings to enable adjustments in cyanogen settings

Thanks that worked I misread the post earlier I thought it said to turn it off. :_con:

I tried these settings, and I'm not sure about anyone else, but the screen is REALLY dim. Like almost unusable. Maybe it's me just being used to a brighter screen, but does anyone else share these feelings?

i agree it is very dim when the lights are off but just remember this is the OP's personal settings you may have to tweak a little to get what you like...

 

[Morphinity]

Right. Also, it's kind of sporadic. Sometimes I would turn the phone on and it would be very dim and it would stay that way. Sometimes I would turn the phone on and it would be bright and it would stay that way. And sometimes I would turn the phone on and it would start at one brightness, but change as time went by.

Very strange. I guess I have to work with it.

 

[pizzlewizzle]

i just started messing around with it dismorning its pretty cool....i'm guessing the light sensor is around where the ear piece is. If you put your phone under light the screen gets brighter and if you slip your hand over the upper half of the phone it dims. If your phone is to dark change the 1st value for screen from 2 to 5 or however bright you want it... besides that you may just want to mess around with some other values... for screen and button values 255 is 100% brightness and 0 is off or 0% brightness

 

[antintyty]

how do you get to these settings?

 

[Guest]

how do you get to these settings?

Settings>CyanogenMod settings>Display>Automatic backlight

Once you get there, you'll be able to edit all of the settings mentioned in the original post. Be sure to change the amount of light levels to 8 and simply adjust the values to the onee shown in the picture. Also, the fourth value in the leftmost column should be a 65 instead of a 50 (picture shows a 50, but the instructions specify 65). Hope that helps!

 

[unchoney]

Thank you kind sir! Display dropped from 40% to 18%! Now my go sms is the battery hog!

 

[Crimsongost]

This is just one more reason i love my DX+cm7!

 

[johnjutrasii]

For extra savings you can make all of the numbers in the right most column to zero and will shut the lights off on the bottom buttons all the time.

Is there a reason the buttons are only one brightness? I tried 1-255 and they are always the same brightness like even 1 is full brightness am I doing something wrong

Agreed buttons don't seem to work. First time I tried this the buttons actually became dimmer, now they seem to be stuck on one setting, no matter what the number is. Perhaps a CM bug?

Anything and everything on the quest for more battery. If we do the nightlies daily...heh, do you need to redo this each time you flash. Just set mine up today and gonna see how it does tomorrow. Thanks again man!

Nope! They'll stick just fine when you flash the next nightly.
