If anyone is compiling a kernel, please unset CONFIG_UEVENT_HELPER_PATH.
It is currently set to /sbin/hotplug, which does not exist.
You might also set
echo 5 > /proc/sys/vm/laptop_mode
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
somewhere in the initramfs.
What does these settings do?

if CONFIG_UEVENT_HELPER_PATH is set, then the kernel tries to execute that helper tool every time a hotplug event occurs. Unsetting it would save a lot of forks at boot time.
Code:
echo 5 > /proc/sys/vm/laptop_mode
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
These settings delay the disk writeback, so the disk device has to wake up less often (given it goes into sleep mode ).
Ah okay so i can expect better battery life (more sleep time) and a faster booting.
Well done, thanks.
I hope some devs are going to integreate it.
OK good point to try.
Added now on my Cognition 1.07
Code:
bash-4.1# cat /etc/init.d/90laptop.sh
#!/system/bin/sh
echo 5 > /proc/sys/vm/laptop_mode
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs

If you have the CF-Root kernel installed, you can just place this in /data/local/customboot.sh
Code:
echo 5 > /proc/sys/vm/laptop_mode
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
echo -e '\000\000\000' > /proc/sys/kernel/hotplug

the first two might help. (does Solid State internal storage need "sleep" mode?)
but depending on when the custom script is run the last line may be useless here..
Does it only work with a CF-Kernel, i've tagraks kernel, and cant find any file in data/locel .

It doesn't go into sleep mode since it's not a spinning disk.
(Or you could look at it as always being in sleep mode when not in use - there's no spindown/spinup phase.)
So you're not gonna see any battery benefits from that.
Added into my installation on my handset. No way to test it whether it will increase stabilty nor speed, but it does tidy thinngs up.
I have xperia ray , and recently i used many cyanogenmod versions , fxp045 to fxp054

Adjust or set the brightness manually until the problem is resolved
first i am very thankful to you for reply , you are totally awesome , again thanks for joining xpiera ray forum (i have seen all your posts , so helpful)
I have tried , but still not working
Lemme explore it
Once i have CM7 installed , i go to settings and set brightness to full
then use my device it works good
After i lock it and open it again i find brightness it reduced to half
i go to settings and check it , it shows brightness is set to full but in reality it is not
is there any problem with my bootloader unlocking method ?

It may be a problem with cm7, have you asked in the cm7 thread ?
The brightness works on my the miui roms
Not sure why it doesnt on cm7 so may be rom specific so report on that thread and see if you get any feedback. it may be a known bug
one more question chiefy009 , which miui is best for ray?
and is overclocking not harmful and much battery consuming
Planing to shift on miui

My miui has tweaks for smoothness and extended settings but try them all.
Overclocking does use battery so undervolt as well, undervolting is trial and error to see if your phone remains stable
Overclocking to high could damage the phone if used over a prolonged period of time I would imagine but a quick google search will get you more info

i had this problem to solved using this guide! if is not working with the file edit, use the als_curve.ini (backup first)
I have this in CM 7
# LMU AS3676 Configuration
dev=/sys/devices/i2c-0/0-0040/leds
echo 1,65,255,24,24,5,128 > $dev/lcd-backlight/als/curve # ALS curve for group1
echo 2,0,0,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]
echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 450 > $dev/button-backlight/max_current
Last time i changed the whole code , now i think i have to only change
echo 2,0,0,0 TO echo 0,0,0,0
right ?
i replaced lights.semc.so with stock lights.semc.so file , in system/lib/hw
brightness works but only problem is LED light always turn on , in pink color

That's right, only change the "echo x,x,x,x" phrase.
I tried "echo 3,2,2,0" and "echo 1.5,1,0.5,0 30h". I dont realy know what these parameters exaktly mean, but "echo 1.5,1,0.5,0 30h" works fine on my ray.
You also can change your als_curve.ini in system/etc.

Do you mean the flash LED on the back? And does it keep the brightness you set before you locked?

Hello xutienan9520,

And what kind of effect does "echo 0.0.0.0.0.0.0" have to your brightness?

Sorry if this is OT.
But I would like to share some bugs I found while using 1.1A as I didn't upgrade to 1.4 as the links were down. Can you verify whether these are faced by any of you !
1. It takes time to wake up from the lock screen. ie even after a hard key press the screen wakes up after say 3-4 secs.
2. Data connection works with flaws. 2G/3G data seems to be buggy.
3. The notification power widget and power widget doesnt work properly. ie, even if i disable/enable Data/Orientation Lock the effect is not applied. I cant even change it in settings. Only solution is a reboot.
4. Incoming call button issues. (Solved in later versions)
Other than these, the rom is pretty stable.
umm I didn't had any of those bugs in v1.1a.actually it was one of the best version because of kernel, except few graphical bugs.anyway,look on last page/page before that of the rom,pm rosuvladut and ask him to upload rom v1.4 to 4shared or another.if he doesn't have it anymore send me a pm and I will upload v1.3 for you when I get home.i personally am lazy to upgrade to v1.4 because the changes are too insignificant.you can upgrade rom manager by yourself, instead of root browser use root explorer.about super charger I don't use it so for me v1.3=v1.4
anyone knows more about why his topic was closed? we could add other download links and that's it.

I checked back in dev thread to see if any of the down links where updated. Was surprised to see no post by trettet about site being down, then noticed thread was locked. Hope all is well.
tread closed? why!
Anyone know why the notifications won't stop making noise until I view them...the sound is very annoying when it doesn't stop? I only want the notification sound once. Awesome ROM btw.

[Hack/Mod] Save Battery with Disabling Button Backlight on Xperia Neo & other Phones
Supported Devices:
Xperia arc and arc S
- .587
- .431
-. 4.0.3
- GB
Xperia Ray
- .587
- .431
-. 4.0.3
- GB
Xperia Neo/V
- .587

And Maybe More
What?
Disabling Button Backlight for Battery Saving and Light Life
How?
1. Mount /system as Read and Write
2. Go To /sys/class/leds/button-backlight and change brightness and max_current to "1".
3. Go To /system/etc/hw_config and scroll down a bit. Now Change max_current to "1", too.
4. Reboot. Buttons Light will not light up anymore.
About the Attached File - just extract Disable/enable.zip to sys and than change hw_config.
For Disabling Just change hw_config ---> max_current to 455. ---> Download
[highlight]Hit Thanks is appreciated. It took about 1h to explorer that "Hack". Dont tell me thanks good work - I know that - just use the Thanks button it counts more. Thanks![/highlight]

Is it really save a battery...
Because I think this backlight not use as much power of battery...

Neo V has two button backlight, so if you own a Neo V, or if you are using a rom like pureness (which developer has neo V)...you will find these settings rgb1 and rgb2.
I have a Neo, but I use pureness so I must edit both.
So, go to
Go To /sys/class/leds/button-backlight-rgb1 and change brightness to 0 and max_current to "1". Do the same in the folder "button-backlight-rgb2.
Then Go To /system/etc/hw_config.sh and scroll down all the text. In the last block you have (not directly in order):
echo 1 > $dev/button-backlight-rgb1/als/enable #Sensor on/off. 1 = on, reg 90h
echo 1 > $dev/button-backlight-rgb2/als/enable #Sensor on/off. 1 = on, reg 90h
change to
echo 0 > $dev/button-backlight-rgb1/als/enable #Sensor on/off. 1 = on, reg 90h
echo 0 > $dev/button-backlight-rgb2/als/enable #Sensor on/off. 1 = on, reg 90h
then under some lines get
echo 900 > $dev/button-backlight-rgb1/max_current #Max current in uA
echo 900 > $dev/button-backlight-rgb2/max_current #Max current in uA
change to
echo 1 > $dev/button-backlight-rgb1/max_current #Max current in uA
echo 1 > $dev/button-backlight-rgb2/max_current #Max current in uA

@jader13254: was this thread on another section? I remember I posted somewhere... anyway I tried to suggest your mod to ThilinaC more times, but he seemed not to hear me... are there any bad consequences from this mod?
And what about battery life?

I'm using init.d script instead of editing the hw_config. When u want to enable it later on, just delete the script. Works on my I-Scream 587. Also works on my friend's arc s, but need to edit it a bit.
But the concept is mostly the same.
Code:
#!/system/bin/sh
#added by emannxperia on 19 Sept 2012
if [ -e /sys/class/leds/button-backlight-rgb1/brightness ]; then
echo "1" > /sys/class/leds/button-backlight-rgb1/brightness
fi
if [ -e /sys/class/leds/button-backlight-rgb1/max_current ]; then
echo "1" > /sys/class/leds/button-backlight-rgb1/max_current
fi
if [ -e /sys/class/leds/button-backlight-rgb2/brightness ]; then
echo "1" > /sys/class/leds/button-backlight-rgb2/brightness
fi
if [ -e /sys/class/leds/button-backlight-rgb2/max_current ]; then
echo "1" > /sys/class/leds/button-backlight-rgb2/max_current
fi
it worked Thanks

I think the backlight is quite useful too to disable it.
However may I know if there is any way to disable Home key during sleep mode? To wake the phone, simply just press the Power key at the side.
I hate to see my phone always accidentally turned on when I put it in my pocket (somehow because of wearing tight jeans, Home key can be accidentally pressed).
Thanks

Why? It lights only when the screen is on...or not?
Is the backlight really signficative for the battery economy?

Disabling Button Backlight for Battery Saving and Light Life
How?
1. Mount /system as Read and Write
2. Go To /sys/class/leds/button-backlight and change brightness and max_current to "1".
3. Go To /system/etc/hw_config and scroll down a bit. Now Change max_current to "1", too.
4. Reboot. Buttons Light will not light up anymore.
About the Attached File - just extract Disable/enable.zip to sys and than change hw_config.
For Disabling Just change hw_config ---> max_current to 455. ---> Download
[highlight]Hit Thanks is appreciated. It took about 1h to explorer that "Hack". Dont tell me thanks good work - I know that - just use the Thanks button it counts more. Thanks![/highlight]

Ok, I think that to do it, I have tobuy and use Root Explorer, isn't it?

You can try Root browser lite! Or else you can use Notepad ++ on pc for editing!

Just root app. You can use 'Es File Explorer' App. Change settings to enable superuser. (Device must be rooted)
Go to Settings>Root Settings>
Check 'Root Explorer' and 'Mount File System'
then follow jaders steps listed above

2. Open Root Explorer
3. Goto Root\system\etc
4. Open hw_config.sh
5. Scroll Down to the Last line and add these lines after it.(in the line after last line)
6. # Button Backlight Configuration
7. echo 1 > $dev/button-backlight/max_current
8. Save the file
9. Restart your phone

Nice guide, you can do this without Root Explorer too, using the default CM File Manager with enabled root access

Envoyé depuis mon Super Arc à flèche nommé Arc S.
on CM10 works perfect.
@avinash thanks for reply in my pm..is it possible that keylight could be kernel related? Because when I use the old pacman 4.2.2 kernel by shardul, the keylight is gone. When I used the pacman nAa-03 based kernel inside rom zip the keylight is present..I already PM you the download link for pacman 4.2.2 nightly build for 2011 Xperia..maybe you can test the rom for your device, its working good..
For me Linus Torvalds is the greatest man on earth

no bro
keylight has nothing to do with kernel
they are two separate builds that you are using although they are based on similar source code
the hw_config.sh isn't modified in the link that you pm me
just edit the hw_config.sh your problem will be solved
it's not a big deal
