[Q] huge laggs on *simple* games

Hello community,
Im having a rooted kf with cm7 and Im a beginner
Id like to tell you my problem. I was trying to play several games starting with fruit ninja or world of goo and was suprised by really low fps around ~5. Im having setcpu from the forum without any additional settings. Its really not fun and I wonder how some of you can plwy mw CoD f.e. .
I wonder whether youre having any additional program on your kf or any advice for me.
Thanks

hello jvizz
this works also on cm7:
http://forum.xda-developers.com/showthread.php?t=1412663
use editor on kf to edit - beware of the permissions
maybe this helps ...

Hello
I have done this the very first day.
That gave a real boost from 1 to 5 fps hehe

there are some tweaks for build.prop - did you something ?
but as allways - beware the permissions !

I will try tomorrow, thanks

in /system/build.prop - i use es file exploer for editing (adding at the end)
settings are active after reboot
and use only the ones you need
try it one after the other for testing
i used:
debug.sf.hw=1
video.accelerate.hw=1
and it gave a performance boost in quadrant
double check what you do - you can brick it

Im having the trouble its not saving. Seems not be writable. Can I add this anyway?

if you'r using es file explorer you have to set "root explorer" and i think "mount file system" in settings. if superuser asks then yes and remember.
there is also a way to copy it to computer with adb but it's risk is to set wrong permissions - would try with es first

Hi. I need to try this.
Should i add the lines I try at the end of build.proportional?

yes - simply add the new lines at the end of build.prop

Hey,
I tried that. My system seems to be quicker Button there is no improvement online apps

I really don`t get it how this guy could have made this video playing all the games lagging on my device:

do you talk about online games ? that depends on the network speed also
i don't think the guy shows online games
furthermore i'm not the game expert - sorry - can't help you much further

I know youre not an expert for this
Maybe you can find the problem here :
In setcpu is written that only a very low amount of RAM is free. About only 80mb are free to usw.
Any idea?

no - sorry - i don't have setcpu - allthrough i know there are some performance settings in setcpu but i'm pretty shure you allready tried to fiddle with it - the used ram is how android work - it is loading/unloading apps on demand - i think there are also settings in setcpu where you can change the values when an app will be unloaded

Need some HELP with a few build.prop tweaks !

Heya guys if someone could just try these build.prop tweaks or tell me whether these actually work on SGY i'd be gratefull ! i tried but can't be sure so if anyone espeacially on stock can help then it is appreciated ! thanks in advance

Like i said in the above post i tried but didn't see any difference so i need to know whether these are valid or not !

type getprop and you'll see your tweak there.

thanks kuro! that was all I needed!

nope...that command only use to check whether your script is executed or not. it doesnt tell you whether if the new prop really working or not.
EDIT:
if you want a proof, in terminal type
Code:
su
setprop kucing.meong.lucu 1
getprop
you'll find kucing.meong.lucu in your prop list.

Okay got it!
My scripts are getting executed btw is there a way to know whether they are working?

unless if you know all the prop stuff inside android system, you'll never know which one is really working or not. some of rom have additional hidden prop. some of prop mod will work on all rom but some of them only work in certain rom. in your tweak,
Code:
# Render UI with GPU
debug.sf.hw=1
persist.sys.composition.type=gpu
# this one will mostly working. however, the differences isn't significant.
#Lock Launcher in memory
ro.HOME_APP_ADJ=1
# seems doesn't work in ICS
# Increase overall touch responsiveness
debug.performance.tuning=1 #work
video.accelerate.hw=1 #work
windowsmgr.max_events_per_sec=250 # the max value is 90. when you set higher than 90 you'll get nothing.
#Save Some battery
pm.sleep_mode=1 #work
# Improve overall media quality
ro.media.enc.jpeg.quality=100 #work
ro.media.dec.jpeg.memcap=8000000 # I highly doubt this one.
ro.media.enc.hprof.vid.bps=8000000 #work
# Tweaks for battery saving
pm.sleep_mode=1
wifi.supplicant_scan_interval=120 #work. be carefull with the value
# Turn on Just In Time in dalvik virtual machine
dalvik.vm.execution-mode=int:jit #the devault set is jit. no need to set it again.
# the other famous stuff,
dalvik.vm.heapsize=128m #if you set it higher than 64 it doesn't affect your system. 48 is enough. it doesn't matter since it doesn't improve your devices performance at all

Okay thanks kuro learned a lot from you!

[Guide]Build.prop Wiki

Alright great N2 users!
I´m Chris from Omega Team and today I present to you my little tutorial about build.prop file. Couldn't find something similar in here, so I decided to start this thread. I already got a thread about it in Galaxy S3 section and decided to port it also to Note 2 forum.
So before I start just one thing. It took me many hours to get all the information and as you can see there are still some points missing. So if you got some information about them, please pm me and for sure I put you on the credit list! If you try to mod the build.prop, please back it up first and make a nandroid backup in case something went wrong. Also don´t do anything unless you have a clue about it! Please hit thanks if you think the information in here are useful! And I´m glade for any feedback and suggestion from you guys! I´m not responsible for any damage you phone get when you messing around with this values!
Credits:
To Vegeta1, for give me a first start and his great support!
To Omega Rom Team, for their great support and being like a second family!
1. You will find the build.prop file in root path/System. You can open it with a build.prop editor from Play store or open it for example with the build in text editor in an app like root explorer.
2. For what you need a build.prop? Here´s a good explanation from TheManii: Build.prop is what holds the majority of the runtime flags that are used when android boots, think of it as being similar to config.sys on dos or environment variables in various OS's. It only holds variables, it cant run any scripts on it's own. Whatever is placed inside depends on android itself to pay attention to the flag and actually use it.
3. Let´s get started
# begin build properties
# autogenerated by buildinfo.sh
Version Number of 4.1.2
ro.build.id=JZO54K
Current Rom version on Phone: by editing this value, you will change what are standing in Settings/About Phone/Buildnumber. For Example you can change it to Omega by Indie or what ever you like.
ro.build.display.id=Omega v8.0 - XXDLK7
Your current Modem version
ro.build.version.incremental=N7100XXDLK7
Current sdk version of Framework plus Codename
ro.build.version.sdk=16
ro.build.version.codename=REL
Android Version on Phone
ro.build.version.release=4.1.2
Current Kernel version
ro.build.date=Mon Nov 26 18:23:18 KST 2012
ro.build.date.utc=1353921798
ro.build.type=user
ro.build.user=se.infra
ro.build.host=SEP-78
This means its a official release
ro.build.tags=release-keys
Model Number plus Manufacturer
ro.product.model=GT-N7100
ro.product.brand=samsung
Name
ro.product.name=t03gxx
Device
ro.product.device=t03g
The phone’s board is listed as “smdk4x12,” which means it will most likely use Exynos 4212 or 4412 supporting a maximum clock speed of 1.4GHz (1.6GHz).
ro.product.board=smdk4x12
System Images
ro.product.cpu.abi=armeabi-v7a
ro.product.cpu.abi2=armeabi
ro.product_ship=true
Nothing to say
ro.product.manufacturer=samsung
Current default Country settings. If you change that line for example to ro.product.locale.language=de and ro.product.locale.region=De, the phone will set to German after a factory reset
ro.product.locale.language=en
ro.product.locale.region=GB
If you not able to connect to your wifi, you can try to set here the same number of channels as your router currently got. For example: Your router is set to 14 channels you can paste the same number in here.
ro.wifi.channels=
Nothing interest on the next few points. Most are explained above.
ro.board.platform=exynos4
# ro.build.product is obsolete; use ro.product.device
ro.build.product=t03g
# Do not try to parse ro.build.description or .fingerprint
ro.build.description=t03gxx-user 4.1.2 JZO54K N7100XXDLK7 release-keys
ro.build.fingerprint=samsung/t03gxx/t03g:4.1.2/JZO54K/N7100XXDLK7:user/release-keys
ro.build.characteristics=default
# Samsung Specific Properties
ro.build.PDA=N7100XXDLK7
ro.build.hidden_ver=N7100XXDLK7
ro.build.changelist=590308
# end build properties
#
# system.prop for smdk4x12
#
Ril Specific: Here some from aosp to that: RIL daemon reads rild.lib path and rild.libargs system properties to determine the Vendor RIL library to use and any initialization arguments to provide to the Vendor RIL
rild.libpath=/system/lib/libsec-ril.so
rild.libargs=-d /dev/ttyS0
Here you can set the Pixel per inch. The smaller you set it the smaller apps, icons and fonts will be. But be careful if you set it to low apps can crash! Also you can´t set it higher than the default value!
ro.sf.lcd_density=320
Minimum brightness of your screen
ro.lcd_min_brightness=20
This point is about rooting. It´s setting if the device running on the emulator or running in secure mode
ro.kernel.qemu=0
This point speak for itself
ro.tvout.enable=true
Maybe someone can light me up on that point.
persist.sys.storage_preload=1
Same here
net.streaming.rtsp.uaprof=http://wap.samsungmobile.com/uaprof/
# Multimedia property for Smart View
media.enable-commonsource=true
# System property ril adb log on
persist.radio.adb_log_on=1
#
# ADDITIONAL_BUILD_PROPERTIES
#
Support for OpenGl 2.0
ro.opengles.version=131072
System property used to enable or disable dirty regions invalidation.
debug.hwui.render_dirty_regions=false
Same as above, setting the pixel per inch
ro.sf.lcd_density=320
System property defining default error report receiver
ro.error.receiver.default=com.samsung.receiver.error
This controls the smallest amount of memory given to a single application.
dalvik.vm.heapstartsize=8m
The dalvik.vm.heapgrowthlimit property limits how large an Android application’s heap can get.
dalvik.vm.heapgrowthlimit=64m
The dalvik.vm.heapsize property defines an absolute maximum for the heap size for an application.
dalvik.vm.heapsize=256m
No clue about the next three points. Help is appreciated.
ro.hdcp2.rx=tz
ro.secwvk=220
ro.sec.fle.encryption=true
Here you can set the standard media sounds for each notification. But they got to match with the one in system/media/audio/...
ro.config.ringtone=S_Over_the_horizon.ogg
ro.config.notification_sound=S_Whistle.ogg
ro.config.alarm_alert=Walk_in_the_forest.ogg
ro.config.media_sound=Media_preview_Touch_the_light.ogg
That means your phone is still usable, even you got no Sim card in it.
keyguard.no_require_sim=true
Format of date
ro.com.android.dateformat=MM-dd-yyyy
Setting this value from unknown to wifi-only can fix some stand by issues.
ro.carrier=unknown
Needed for Play store. Some guys modded it to pay with her Phone bill, but i don't know if that still works.
ro.com.google.clientidbase=android-samsung
Defines weither to use UMTS (0), HSPDA/UMTS(1), or HSDPA/HSPUA(2) respectively.Here you can improve your Data speed if your provider supports it. Set this to 0 if you want lower speeds, and up to 2 for faster speeds.
ro.ril.hsxpa=1
Defines what class speeds to use with EDGE. Setting this value to 12 can improve the data speed significant on lower connections.
ro.ril.gprsclass=10
Value for adb. Is a pipe connection in the adb client.
ro.adb.qemud=1
Google Mobile Service Version with build number
ro.com.google.gmsversion=4.1_r3
Basically you control the class-loading and dalvik-vm there. Here you can set different values. v=a means verify all, v=f means verify full, o=v means optimize verify, u=n means do not optimize for unprocessor and m=y means register maps yes
dalvik.vm.dexopt-flags=m=y
Bluetooth name of the device
net.bt.name=Android
The dalvik.vm.stack-trace-file property allows you to specify the name of the file where the thread stack traces will be written.
dalvik.vm.stack-trace-file=/data/anr/traces.txt
This point stands for "Debug SurfaceFlinger Hardware" or GPU hardware acceleration
debug.sf.hw=1
Video Acceleration
video.accelerate.hw=1
Increase the touch responsive of the screen
debug.performance.tuning=1
Disable sending usage data
ro.config.nocheckin=1
Increase the quality of JPEG pics
ro.media.enc.jpeg.quality=100
increasing the recording quality of Pics and videos
ro.media.dec.jpeg.memcap=8000000
ro.media.enc.hprof.vid.bps=8000000
Here you can set the delay of time your phone starts to ring when you recieve a call. 0=disabled
ro.telephony.call_ring.delay=0
This point set the delay after a call. This fix Black screen issues.
ro.lge.proximity.delay=15
mot.proximity.delay=15
Next two points should safe some battery if they are enabled but the problem is that they are not in source code elsewhere and should have no effect. This means that adding this value to your build.prop will have no effect at all. This parameter is a kernel parameter and will only work when passed directly to the kernel on boot.
ro.ril.disable.power.collapse=0
pm.sleep_mode=1
Already explained
ro.config.nocheckin=1
For the last two points. These commands enable or disable the error profiler in the android. For most android users, there is no use in having error profiling . however , some applications might make use of this for generating error reports.
profiler.force_disable_err_rpt=1
profiler.force_disable_ulog=1

No it won't change csc. If you modified it in the rom zip and flash the rom afterwards with full wipe it will automatically set phone to the region you modified before.
Edit: Are you sure about the other two? If yes that would be perfect!

What will happen if we put more than 800000000 for the quality of pics ?
And now I've already android 4.2

I'm not quiet sure. But i think the actual number should be the maximum or a little bit above. But it can't get better then better. Otherwise you could imagine what numbers I would past in for some points.

I know my friend but also to you for sharing this.

I am not sure.
But from the name I think they could be.
Try chainfire or some rom dev dto confirm.
I might be completely right or maybe completely wrong

Will do it. Thank you for your help!

Adding a line to build.prop (at the end) will enable sofykey navigation bar(virtual key) like nexus
qemu.hw.mainkeys=0
below mentioned thing is not related to build prop but it is useful when you add navigation bar with build prop
You can disable hardware button by editing
/system/usr/layout/Generic.kl
there are three key 172, 158,139 for Home,Back and menu.
add # before number of key to disable it.
Sources : I have read somwhere and sorry original source not knowing.

Hi mate! Sorry for my late reply. You can't change the Mac address in build prop. You can just change the number of channels your router use. It can help with stand by issues.

[Guide]Build.prop Wiki

Alright great S2 users!
I´m Chris from Omega Team and today I present to you my little tutorial about build.prop file. Couldn't find something similar in here, so I decided to start this thread. I already got a thread about it in Galaxy S3 section and decided to port it also to Galaxy S2 forum.
So before I start just one thing. It took me many hours to get all the information and as you can see there are still some points missing. So if you got some information about them, please pm me and for sure I put you on the credit list! If you try to mod the build.prop, please back it up first and make a nandroid backup in case something went wrong. Also don´t do anything unless you have a clue about it! Please hit thanks if you think the information in here are useful! And I´m glade for any feedback and suggestion from you guys! I´m not responsible for any damage you phone get when you messing around with this values!
Credits:
To Vegeta1, for give me a first start and his great support!
To Omega Rom Team, for their great support and being like a second family!
1. You will find the build.prop file in root path/System. You can open it with a build.prop editor from Play store or open it for example with the build in text editor in an app like root explorer.
2. For what you need a build.prop? Here´s a good explanation from TheManii: Build.prop is what holds the majority of the runtime flags that are used when android boots, think of it as being similar to config.sys on dos or environment variables in various OS's. It only holds variables, it cant run any scripts on it's own. Whatever is placed inside depends on android itself to pay attention to the flag and actually use it.
3. Let´s get started
# begin build properties
# autogenerated by buildinfo.sh
Version Number of 4.1.2
ro.build.id=JZO54K
Current Rom version on Phone: by editing this value, you will change what are standing in Settings/About Phone/Buildnumber. For Example you can change it to Omega by Indie or what ever you like.
ro.build.display.id=Omega v16.2 - XXLSJ
Your current Modem version
ro.build.version.incremental=I9100XXLSJ
Current sdk version of Framework plus Codename
ro.build.version.sdk=16
ro.build.version.codename=REL
Android Version on Phone
ro.build.version.release=4.1.2
Current Kernel version
ro.build.date=Tue Nov 6 02:17:01 KST 2012
ro.build.date.utc=1352135821
ro.build.type=user
ro.build.user=se.infra
ro.build.host=SEP-111
This means its a official release
ro.build.tags=release-keys
Model Number plus Manufacturer
ro.product.model=GT-I9100
ro.product.brand=samsung
Name
ro.product.name=GT-I9100
Device
ro.product.device=GT-I9100
The phone’s board is listed as “smdk4210,” which means it will most likely use Exynos 4210, supporting a maximum clock speed of 1.2GHz.
ro.product.board=smdk4210
System Images
ro.product.cpu.abi=armeabi-v7a
ro.product.cpu.abi2=armeabi
ro.product_ship=true
Nothing to say
ro.product.manufacturer=samsung
Current default Country settings. If you change that line for example to ro.product.locale.language=de and ro.product.locale.region=De, the phone will set to German after a factory reset
ro.product.locale.language=en
ro.product.locale.region=GB
If you not able to connect to your wifi, you can try to set here the same number of channels as your router currently got. For example: Your router is set to 14 channels you can paste the same number in here.
ro.wifi.channels=
Nothing interest on the next few points. Most are explained above.
ro.board.platform=exynos4
# ro.build.product is obsolete; use ro.product.device
ro.build.product=GT-I9100
# Do not try to parse ro.build.description or .fingerprint
ro.build.description=GT-I9100-user 4.1.2 JZO54K I9100XXLSJ release-keys
ro.build.fingerprint=samsung/GT-I9100/GT-I9100:4.1.2/JZO54K/I9100XXLSJ:user/release-keys
ro.build.characteristics=default
# Samsung Specific Properties
ro.build.PDA=I9100XXLSJ
ro.build.hidden_ver=I9100XXLSJ
ro.build.changelist=462349
# end build properties
#
# system.prop for smdk4210
#
Ril Specific: Here some from aosp to that: RIL daemon reads rild.lib path and rild.libargs system properties to determine the Vendor RIL library to use and any initialization arguments to provide to the Vendor RIL
rild.libpath=/system/lib/libsec-ril.so
rild.libargs=-d /dev/ttyS0
Here you can set the Pixel per inch. The smaller you set it the smaller apps, icons and fonts will be. But be careful if you set it to low apps can crash! Also you can´t set it higher than the default value!
ro.sf.lcd_density=240
Minimum brightness of your screen
ro.lcd_min_brightness=40
This point is about rooting. It´s setting if the device running on the emulator or running in secure mode
ro.kernel.qemu=0
This point speak for itself
ro.tvout.enable=true
Maybe someone can light me up on that point.
persist.sys.storage_preload=1
Same here
net.streaming.rtsp.uaprof=http://wap.samsungmobile.com/uaprof/
# Multimedia property for Smart View
media.enable-commonsource=true
# System property for Default Brightness
I think this point also need no explanation
ro.lcd_brightness=160
#
# ADDITIONAL_BUILD_PROPERTIES
#
Support for OpenGl 2.0
ro.opengles.version=131072
System property used to enable or disable dirty regions invalidation.
debug.hwui.render_dirty_regions=false
System property defining default error report receiver
ro.error.receiver.default=com.samsung.receiver.error
This controls the smallest amount of memory given to a single application.
dalvik.vm.heapstartsize=5m
The dalvik.vm.heapgrowthlimit property limits how large an Android application’s heap can get.
dalvik.vm.heapgrowthlimit=48m
The dalvik.vm.heapsize property defines an absolute maximum for the heap size for an application.
dalvik.vm.heapsize=128m
Same as above, setting the pixel per inch
ro.sf.lcd_density=240
No clue about the next point. Help is appreciated.
ro.sec.fle.encryption=true
Here you can set the standard media sounds for each notification. But they got to match with the one in system/media/audio/...
ro.config.ringtone=S_Over_the_horizon.ogg
ro.config.notification_sound=S_Whistle.ogg
ro.config.alarm_alert=A_toy_watch.ogg
ro.config.media_sound=Media_preview_Touch_the_light.ogg
That means your phone is still usable, even you got no Sim card in it.
keyguard.no_require_sim=true
Format of date
ro.com.android.dateformat=MM-dd-yyyy
Setting this value from unknown to wifi-only can fix some stand by issues.
ro.carrier=unknown
Needed for Play store. Some guys modded it to pay with her Phone bill, but i don't know if that still works.
ro.com.google.clientidbase=android-samsung
Defines weither to use UMTS (0), HSPDA/UMTS(1), or HSDPA/HSPUA(2) respectively.Here you can improve your Data speed if your provider supports it. Set this to 0 if you want lower speeds, and up to 2 for faster speeds.
ro.ril.hsxpa=1
Defines what class speeds to use with EDGE. Setting this value to 12 can improve the data speed significant on lower connections.
ro.ril.gprsclass=10
Value for adb. Is a pipe connection in the adb client.
ro.adb.qemud=1
No clue. Maybe someone can light me up.
ro.com.google.apphider=off
Google Mobile Service Version with build number
ro.com.google.gmsversion=4.1_r3
Basically you control the class-loading and dalvik-vm there. Here you can set different values. v=a means verify all, v=f means verify full, o=v means optimize verify, u=n means do not optimize for unprocessor and m=y means register maps yes
dalvik.vm.dexopt-flags=m=y
Bluetooth name of the device
net.bt.name=Android
The dalvik.vm.stack-trace-file property allows you to specify the name of the file where the thread stack traces will be written.
dalvik.vm.stack-trace-file=/data/anr/traces.txt
This point stands for "Debug SurfaceFlinger Hardware" or GPU hardware acceleration
debug.sf.hw=1
Video Acceleration
video.accelerate.hw=1
Increase the touch responsive of the screen
debug.performance.tuning=1
Disable sending usage data
ro.config.nocheckin=1
Increase the quality of JPEG pics
ro.media.enc.jpeg.quality=100
increasing the recording quality of Pics and videos
ro.media.dec.jpeg.memcap=8000000
ro.media.enc.hprof.vid.bps=8000000
Here you can set the delay of time your phone starts to ring when you recieve a call. 0=disabled
ro.telephony.call_ring.delay=0
This point set the delay after a call. This fix Black screen issues.
ro.lge.proximity.delay=15
mot.proximity.delay=15
Next two points should safe some battery if they are enabled but the problem is that they are not in source code elsewhere and should have no effect. This means that adding this value to your build.prop will have no effect at all. This parameter is a kernel parameter and will only work when passed directly to the kernel on boot.
ro.ril.disable.power.collapse=0
pm.sleep_mode=1
Already explained
ro.config.nocheckin=1
For the last two points. These commands enable or disable the error profiler in the android. For most android users, there is no use in having error profiling . however , some applications might make use of this for generating error reports.
profiler.force_disable_err_rpt=1
profiler.force_disable_ulog=1

Is it possible to have conditional statements in build.prop?
Is it possible to have conditional statements in build.prop?
For example:
if P1 == 0
ro.xxx.yyy=value1
else
ro.xxx.yyy=value2
endif
where P1 is either a parameter or a predefined setting.
Thanks

Build.Prop tweaks working for most on LG G Stylo [Updated 9/18/2015]

Attention if you try this and end up with a brick or your device transforms and tries to destroy you; it's not my fault you did this not me. So just read all of this thread not just the O.P to get out of a bind if you reply with "the thread is too long i wont read it please help" don't expect anything short of "there's a search bar use it"
okay so i thought i'd make this thread over here as well since i'm hosting my threads on both XDA and AF
just a quick copy and paste
Here are some build.prop tweaks that i have tried out, there are plenty of ways to edit the build.prop file i personally use root browser (file explorer) which has a RB Text editor....
So the build prop editors on android tend to cut off the build.prop characters after a certain point so to get around this copy your build.prop from /system to your SD. Then transfer it from SD to the desktop of your computer after your comfortable with the edits; move the "original" one in the SD card to a new sub folder which probably want to name "original prop" then copy the edited one to the root of your SD then replace the one you have in /system then fix the permissions to 0644 and reboot and profit (you can use gedit on Ubuntu or Notepad++ on windows don't know about mac tho)
Does your phone tell you that you need to purchase an upgrade to your plan whenever you try and tether? Depending on your carrier, this line may help:

#property to enable DS2 Dap
audio.dolby.ds2.enable=false (if change to true, would also need to edit lge.music.xml in the etc folder to get it to work) JayBondzeWell has provided the edited file i will upload here but his part of the work (and you just unzip and replace your existing .xml file of the same name then fix permissions to 0644)

Maybe you shouldn't mess with your phone if you dont know what you're doing. Editing the build prop isn't hard and especially isn't if you follow directions and lord forbid you do a little research.

Maybe you shouldn't make assumptions about the level of expertise of random people on the internet. Copy+Paste of those build.prop lines = dead phone. That means that the properties written are wrong. Plain and simple.
No worries though, the fix is really simple now! All I have to do is rip out the logic board, throw it in the trash, and put a new one in! Couldn't be simpler! /s
There is no possible way that you added all of those build.prop tweaks and still ended up with a working phone on the Boost rom. ADB pull your build.prop list and post it here, or it didn't happen.
