That is the correct option.
it means it disables the lower min brightness setting than stock min brightness so your lowest setting is stock min.

I think he's talking about the ultra low brightness kicking in at 10%batt on 2.2.1 and 2.3...
AFAIK it is a new "feature " of samsung. I find it quite annoying too... but in manual brightness you can bypass it by sliding on the notifications bar.

After using the kernel for a week this is the conclusion on batt life that I have:
I compared K13A with K13E:
Both kernels hv excellent batt drain when in idle mode.
But when it comes to usage, K13E will only last me about 7hrs of normal usage. Compared to K13A which could easily last me a minimum of 12hrs. Well, this is just a feedback on the kernels and hope that hardcore could look into why k13a can do much better in terms of batt life and maybe implement the batt saving feature from k13a in his future releases.
Cheers!

Good news. I already have a basic speedmod gingerbread kernel running, with only the sharpness fix.
I will probably release a quick win simple version later today. No cwm or lag fix yet but just the key features like sharpness and hardcoded optimizations.

Great bro! Looking fwd to that. Jz for the understanding, regarding the latest k13e and k13a. may I know wats the main different between those 2 kernels? I came from a programming background so I'm ok with technical terms.thx!

Thanks for the good news. Wait for the test release. CMW and brightness optimization are desired
Thanks for taking time out to work on this. Really missing the sharpness fix in stock Gingerbread.

Just curious, are you working off the new github repo that supercurio started?
Very excited to see the developments! IMO I'm gonna wait for CWM and ext4 until I flash hope it's soon =P
I've heard that Samsung's gingerbread kernel has native ext4 support built in. Is that true, and if so, is that helping you at all?
If I get an error:
What am I supposed to do?
Flash a new ROM with Odin? Or can I recover something from CWM ???

Personally, dun find increased screen sensitivity any useful, tried once before using ultimate kernel, the screen jitters when you leave your finger there while scrolling say a web page.
Unless you are talking about reduced sensitivity which I have not really tried yet.
Sharpness and extra ram and basic cement or at least old recovery or cracked new one.for flashing themes and such is all we need lol. and if possible not to mess with brightness and light response speed at least for this initial release.
Pretty please.
Pretty please.

sounds great!
but don't hurry, take your time to deliver once again the best kernel out there
i can't agree with that
not that you have to include auto brightness tweaks in the first release, but hopefully you are porting that to GB too
its one of the best features of your kernel imo
Make sure that your system folder isn't full or near to full. If it is, uses SGS Tools or Root Explorer to remove some unwanted stuff like fonts etc. Then try again.
@hardcore:
Your kernel is becoming disgustingly good in battery life.
-I have my mum's SGS on k13e t1 - it is currently @ 23% @ 2d20h MIN usage.
-My phone (SGS) is on k13e - it is currently @ 34% @ 1d 10h MED usage.
Never seen my phone surpass the 2 day mark!
Keep it up bro!
Note:
What is the difference between the t1 version that u had and the "final version" of k13e? Was t1 only a BETA release?

can you add the led timeout fix from the thread below?

seems great, hopefully HC can include it
also the new "BLN" option without the need for an app seems nice
Talking about battery...I have only 40% left after 10hours. 55min of screen on and 15min talking. Cant say that im blown away by the battery life but i do like this kernel! Right now im using k13e.

525Hi people. This kernel aims to be fast, compatible, stable, and have good battery life. It makes our Galaxy S run the way it should.
This kernel is for the International Galaxy S (I9000) and Bell Mobility Vibrant (I9000M)
The SpeedMod kernel for the AT&T Captivate is available here: http://xdaforums.com/showthread.php?t=893880
Note: Only lagfixes using EXT4 are robust. Other lagfixes run the risk of data loss on freezing, hard-reboots, or sudden power loss.
WARNING: Before you try any lagfix, make sure that you have enough free space on your Internal SD. You should have at least more free space than data+dbdata+cache combined.
Latest K13E (12-Apr) - Voodoo Sound v7. Lowmemorykiller fixes. Improved display sharpness using AMOLED processing mode in MDNIE. Support for voice calls through headphones. Check here for more info and downloads.

FOR BEGINNERS:
This kernel is based on sztupy's Universal Lagfix: Lagfix and root options are accessible by booting into the Recovery Menu.
To get the best speed, it is recommended that you enable all Tweaks from the Recovery Menu. Tweaks are under SpeedMod features. Info on Tweaks: http://xdaforums.com/showthread.php?t=813309

About USB Mounts:
>>> Click here to download the USB mount fixes. Latest SpeedMod versions do not need this fix. The fix is for using K12E or older with 2.2 ROMs. It fixes the problem where Internal SD mounts as a read-only drive on the PC, or if the External SD does not get mounted.

>>> CLICK HERE to DOWNLOAD the kernels.47Updated test: K12Q-T7:
This version is unbelievably smooth!
Android Logger (logcat) disabled by default (can be re-enabled via Tweaks).
Kernel debug messages have been disabled.
Fixed the super loud notifications with Voodoo Sound.
Changes from K12P:
- Disabled Android Logger (can be re-enabled via Tweaks)
- Disabled all kernel debug messages for efficiency
- Changed boot logo to I897 logo for AT&T Captivate version
- Changed /cache to ext4nj in recommended ext4 lagfix to fix large Market downloads
- Optional IPv6 Privacy support in Tweaks
- Voodoo Sound v2 compatible
- Fixed loud notification problem with headphones
- Fixed popping / clicking noise when music and FM radio is stopped / started
- Better FM Radio sound:
- - Really removed the high pass filter and DRC from FM Radio (restores full bass)
- - Turn on 4FS mode for ADC in FM Radio (smoother high frequencies)
- - Turn on 128x oversampling for ADC and DAC in FM Radio mode
- Adjusted volume of FM Radio and Media Playback to be similar
- General sound quality improvements:
- - Maximized digital mixer output to improve SNR and resolution
- - 128x oversampling option in Voodoo Sound enabled by default
- - Explicitly disable DRC and NG during media playback, if +1.5dB mode is NOT selected
For those people who requested IPv6 privacy, please let me know if it works in this version.41
Its not the ROM or modem. I think its the new Wifi firmware. I've started a thread to collect Wifi firmware versions.
http://xdaforums.com/showthread.php?t=885903
In the meantime, if you want u can experiment. I've created update.zip packages to update/overwrite the wifi firmware (it's in /system/etc/wifi).
You can try to use the older (DXJPA) wifi firmware and see how that does in terms of power.
If you don't like it, you can put back the XXJPY wifi firmware with the other package.
Let me know your findings, if u try it out.
DXJPA wifi firmware is working fine with my XXJPY rom. Gonna check out the battery usage.
FYI:
DXJPA: Firmware version = wl0: Jun 4 2010 14:21:21 version 4.218.214.3
XXJPY: Firmware version = wl0: Nov 16 2010 08:56:21 version 4.218.250.3825SpeedMod + Voodoo Sound test version!
K12L-T5:
Changes from K12K:
- Improvements to FM Radio sound: remove Dynamic Range Compression
- Voodoo Sound v1: FM radio bass fix, controllable headphone output via app
- rear speaker volume +1 for media
- light sensor polling interval changed to 2s instead of 0.5s
(saves battery, more stable brightness levels)
- light sensor sensitivity adjusted so that the screen doesn't turn bright so easily
(saves battery and reduces screen burn)
- adjustments to IO Tweak (super smooth now!)
- changed battery level polling interval to 60 seconds, from 5 seconds
Note that you need Supercurio's Voodoo app to adjust the headphone level. If u don't install it, the default level is the same level as K12K (+1 from Nexus S, or +3 from SGS).
PS. The FM radio sound is really awesome after those voice filters have been removed!
