I am running sparks mod 1.6.4 compcache 32% hack.
I want to change the swappiness to 60.
How would I go about doing this?
Don't do it, it's much too high. I would suggest something around 10-20, i.e. type in terminal:
su
echo 10 > /proc/sys/vm/swappiness
Sent from my Gingerbread on Sapphire using XDA App
Why so low? Just seeking some wisdom.
Thanks.\
Also is this a permanent change or do i have to do this every boot?
This is not a permanent change, you have to apply this every time you reboot your phone. If you want it permanent, you should include it into the /system/bin/compcache script.
Swappiness defines, when data will be put into the swapfile. 100 means, all inactive data can be put into the swap, 0 means, that cached data will be removed first before using the swap. Disadvantage when too much data is within swap: the system speed goes down ... so you have to find a good compromize.

ok so i edited the file and pushed it.
now compcache is not starting and when i type it in the terminal it says permission denied.
Any help?
should i try inputting the command you first gave me into compcache?
After the modification, the compcache file should look something like
...
start)
echo 3 > /proc/sys/vm/drop_caches
modprobe $MODULE
rzscontrol $DEV --disksize_kb=32576 --init
swapon $DEV
echo 10 > /proc/sys/vm/swappiness
;;
...
this is what i have
#!/system/bin/sh
#
# Compcache manager
# [email protected] (cyanogen)
#
DEV=/dev/block/ramzswap0
MODULE=ramzswap
MODULES_DIR=/system/modules/lib/modules/`uname -r`
case "$1" in
start)
echo 3 > /proc/sys/vm/drop_caches
echo 30 > /proc/sys/vm/swappiness
modprobe $MODULE
rzscontrol $DEV --disksize_kb=$2 --init
swapon $DEV
;;
stop)
swapoff $DEV >/dev/null 2>&1
rmmod $MODULE >/dev/null 2>&1
;;
stats)
rzscontrol $DEV --stats
;;
*)
echo "Usage: $0 {start <size>|stop|stats}"
exit 1
esac
exit 0
I cant seem to get it to work.
this is the original too.
it just keeps saying permission denied
You are running the script as root, i.e
> su
# /system/bin/compcache start
to start the script manually?
Before modifing the script, you have to remount /system to set it read-write, otherwise it's read only!
try to fix the permission
I'm trying to make a script that will do a modification to the build.prop on boot.
Usually I flash the cm7 nightly and I pull the build.prop, modify it and push it back before the first boot. The idea is to make it easier for flashing roms on the go. Using custom_backup_list.txt seems to be a viable option but it will keep an old build.prop indefinitely.
Some of the properties that I want to change are
Code:
windowsmgr.max_events_per_sec=100
ro.sf.lcd_density=201
ro.config.ringtone=_Mosquito 16bit.mp3
ro.config.alarm_alert=Alarm_Beep_02.ogg
From what I read today CM7 looks for inituser.sh file at two different locations:
Code:
/sd-ext/userinit.sh
/data/local/userinit.sh
As of now I have tried without success doing the following
Make a userinit.sh script at /data/local with the following code
Code:
#!/system/bin/sh
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
setprop windowsmgr.max_events_per_sec 100
setprop ro.sf.lcd_density 201
setprop ro.config.ringtone "_Mosquito 16bit.mp3"
setprop ro.config.alarm_alert Alarm_Beep_02.ogg
I'm not sure if there's something wrong in the above code, or CM7 is not running the scripts on boot.
EDIT: after adb push the file I do
Code:
adb shell
chmod 755 /data/local/userinit.sh
I've been trying for several hours now. Still get issue with stuck at X.
This is my updated script. Not sure what is wrong...
Using CM7 nightly36
cavs intersectraven
ss4n1 script
dtapp2sd
this is my userinit.sh at /data/local
Code:
#!/system/bin/sh
file=/system/.bproped
if [ -f "$file" ]; then
echo "Done already"
else
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
sed -i 's/ro.sf.lcd_density=240/ro.sf.lcd_density=202/g' /system/build.prop
sed -i '/ro.config.ringtone/d' /system/build.prop
sed -i '/ro.config.alarm_alert/d' /system/build.prop
echo "ro.telephony.call_ring.delay=1000" >> /system/build.prop
echo "ro.config.ringtone=_Mosquito 16bit.mp3" >> /system/build.prop
echo "ro.config.alarm_alert=Alarm_Beep_02.ogg" >> /system/build.prop
echo "windowsmgr.max_events_per_sec=100" >> /system/build.prop
echo > /system/.bproped
fi;
exit 0
I know where you're coming from. Takes a while to customize your phone manually after each nightly, so I actually have a custom script similar to what you're doing, which updates build.prop and other config files (hosts, gps.conf, etc). Only mine is run within the update.zip, using the recovery shell /sbin/sh.
For your method, you can try this ...
Code:
#!/system/bin/sh
MODIFIED=`cat /system/build.prop|grep "zeus_chingon"`
if [ "$MODIFIED" ];
then
echo "Done already"
else
mount -o remount,rw /system
sed -i 's/ro.sf.lcd_density=240/ro.sf.lcd_density=202/g' /system/build.prop
RINGTONE=`cat /system/build.prop|grep "ro.config.ringtone"`
sed -i 's/$RINGTONE/ro.config.ringtone=_Mosquito_16bit.mp3/g' /system/build.prop
ALARM=`cat /system/build.prop|grep "ro.config.alarm_alert"`
sed -i 's/$ALARM/ro.config.alarm_alert=Alarm_Beep_02.ogg/g' /system/build.prop
echo "ro.telephony.call_ring.delay=1000" >> /system/build.prop
echo "windowsmgr.max_events_per_sec=100" >> /system/build.prop
echo "# Modified by zeus_chingon" >> /system/build.prop
mount -o remount,ro /system
fi
EDIT:
My own custom script is HERE. Feel free to modify for your own use.

Thanks for your help, I end up using your zip file with some modification. The problem that I keep encountering is that using the /data/local/userinit.sh method it get stuck on boot at X.
I saw in your buildprop.sh some settings like
Code:
ro.HOME_APP_ADJ=1
ro.HOME_APP_MEM=3072
what does each one do?
I use LauncherPro if that have anything to do with it.
ro.HOME_APP_ADJ determines oom_adj value and ro.HOME_APP_MEM determines memory threshold, for your chosen launcher app. In short, these settings help to keep the launcher resident in memory and thus reduce homescreen lag.
One thing you have know about the ro.* settings in build.prop, are that they are writeable one-time only, i.e. once any ro.* value has been set, it becomes read-only and you cannot use setprop to change it further.
So it seems that your orginal buildprop.sh script add to the first line of build prop by using the
Code:
sed -i '1i\Something' /system/build.prop;
to put it in "higher priority" so that it get run first and overlook the second occurence that might occur in the build.prop afterwards?
So if i want to add something to line number n it would be
sed -i 'ni\something' .......

That's correct.
Build.prop
Hi All,
By default my System folder didn't had the build.prop. i extracted it from the CM7 Rom made some changes and copied it to System folder and rebooted.
Changes ringtone(default) Playa.ogg to Rigel.ogg.
After reboot still Playa.ogg as my default ringtone.
What is figured was my Phone isnt including build.prop file
Any suggestions?
Thanx

I found a script that adds boot audio. In it there is a line calling stagefright, stagefright either doesn't exist on my ROM and I have no clue as to add it.

Not sure if this works , but I will eventually try it , but not now , on my free time.
stagefright indeed is not included , my phone too doesn't have stagefright , if you go to youtube and search for android developement tutorials by "thenewboston" . you'll find 200 videos series , just watch the first 20 ones and you'll learn to use Media which replaces stagefright...I didn't try it yet.
It includes
Our_Player and Media Player and the directory of the song....check it out and give us heads ups!

I appreciate the info, I took a look at his tutorials esp the ones involving animation, he really knows his stuff. I am not a Java programmer by any means and to be honest I find it quite tedious, it's like trying to teach a baby (this case the Dalvik VM) to do basic stuff like draw a green ball took like 20 lines of code!
What I need to know essentially is, do I have to use JAVA to get this to work now? In the past ie ICS and lower, there wasn't a problem with Custom Boot Audio, now with JB it seems it has disappeared from the radar.
I know the binary /system/bin/bootanimation (is this written in JAVA?, is there a source code for this bin?) is called at boot time by init.rc in the following manner:
Code:
service bootanim /system/bin/bootanimation
class main
user graphics
group graphics
disabled
oneshot
/system/bin/bootanimation (at least from what I gather) looks in /system/media for bootanimation.zip (zipped in store mode) decompresses it , looks at desc.txt for the code and displays the animation png by png.
In some desc.txt there is an s line, example:
Code:
# mobility
p 1 0 SOUND
s transdroid.mp3
which is SUPPOSED TO call a custom boot audio from /system/media (.mp3?) at the same time. This appears not to work. So logicaly I think the binary needs some tweaking. Can you offer any suggestions?
As you can see I have spent ALLOT of time mulling over why this,one would think, simple task: display a series of images and play audio at boot time I mean how hard can that be?
I am not trying to be a pest I just need to know WHY this doesn't work in JB (CM10.1)
Finally got a new battery after over a year of not using my Droid 4.
Flashed latest CM13 nightly, 1.4ghz OC. Everything seems slow.
My 512mb ram single core $19 cheapo runs smoother.
Anything I do has a half-second or so delay, clean install with nothing running in the background.
Ideally I would just go back to some minimal 2.3.7 ROM, but compatiblity for new programs is getting iffy.
So, as of 2016, what has the smoothest ROM to do date been?

I'm running very, very debloated, overclocked stock JB 4.1.2 with Greenify and ram manager and it works pretty well. Even most of new games and emulators rund good.
Cyanogenmod 11 is quite good. One thing I noticed is that the virtual ROM slots are extremely slow, due to the loopback devices.
One way to go is to install the ROM to the virtual ROM slots to test if they are working correctly and then install it into stock slot for real use.
Up, same question here
I use cm11 or cm12 (i find cm13 extremely slow) But with the following tweaks made from my daily experience feel free to try it

Thank you man, this script made my droid 4 a whole lot more responsive and it does not reboot every few hours anymore.
Quite a few commands in that script don't work, probably due to different paths (sio plus as io scheduler and stock rom boot slot), but those that work, really seem to help a lot.
Oh and you should update the comment in that script about the zram size.

Was testing on different Kernels that's why the paths are wrong.. Please replace the sio plus with cfq or bfq (i forgot to change that)
I am glad that those tweaks help you

What about this one? Mentor's ROM http://forum.xda-developers.com/showthread.php?t=2122709
That's what I found on my used Droid 4... should I give it a try?

why replace sio plus? I used bfq before, but when i googled for sio plus i only found people saying that sio plus was the best of them all.

If your kernel support sio plus, of course use it.. else cfq or bfq is a good alternative

I use cm11 or cm12 (i find cm13 extremely slow) But with the following tweaks made from my daily experience feel free to try it

What am I supposed to do with these lines? And can somebody please explain what they are doing specifically?
I was trying to find a way to enable zram to cope with the small amount of memory. swap ram is an alternative, but i heard zram is faster and not stressing the storage like swap ram would.
hi guys,im running a script on my n9005 aosp kitkat and after 30-60 minutes seems that turn itself down or hanging..can anyone help me with some loop-repeat command to made this script non stop?
the script:
#!/system/bin/sh
echo mmc2 > /sys/class/leds/led:rgb_green/trigger;
echo mmc1 > /sys/class/leds/led:rgb_red/trigger;
echo mmc0 > /sys/class/leds/led:rgb_blue/trigger;
