There's a thread called home screenshots in the theme and apps section where you can take a look at how some ppl have their home screens set up with different launchers, themes, widgets, and icons that way you can get some ideas of how you might wanna set things up as for roms it's really up to you and which you like better there's no harm in trying each one til you find your daily driver remember you can always mix different roms and kernels and find what combo works best for you (just remember to stick to roms and kernels that are for our specific model you don't wanna end up with your first android paper weight) .. Btw I was the same had been using iPhones since the first one to the iphone4 and this was my first Android and haven't looked back since love this phone it's a beast!

If you want to change the lockscreen around, try milocker. Its free and there are alot of options, plus you can change your lockscreen wallpaper.

I plugged in a usb disk of 16gb, and it tells me that additional power is needed for the tab to read it, is it?
[Galaxy Tab 8.9 General] keijames:
if you has a good low votage version of 16GB, then it will works.

can some one provide me the ICS background image file..the one that shows up in settings,log,contacts...etc
[Galaxy S II Themes and Apps] KcDaRookie:
Could you provida a picture showing what you mean?

Its pure black to me, on the one its black to blueish but am not sure if this is what you mean
[LG Optimus 2x] alediniz:
I'll not use this moment, because I use CM7 + vadonka's kernel. But I followed the topic and kernel development, for future testing based on a stock rom. Thanks Stefan.
[LG Optimus 2x] Lo_RaT_PeNaT:
totally agree with your initial paragraph, personally I envy the knowledge that shows every day spica, but for the ignorant like me, is much more useful to mention kernel set, and while this is a personal opinion, maybe instead so many parameters to configure, it would be more useful, use presets as a function of the tastes of each user, power, response, saving battery etc etc, well, maybe not the right place here, well, in principle, its kernel is installed normally, it may seem silly but I assure you it is not, say my phone is very special in terms of internal modificaiones already the slightest forces blocked at the moment I tried connecting wifi perfect, seamless gPS, fM radio without problems and later proves the bt. As for the rom, I'm wearing the carburano and is perfectly smooth, no lags etc., for the moment .... we know that android is the opposite of wines worsen over time. Best regards, and I hope this is not really your last job for our phone, I say sincerely.
[LG Optimus 2x] Divyan:
Stefan,

Thank you very much for this kernel, installed without thinking and testing it now. Couple of observation I made, and opinion I have about the testing stuff.

1. I have no experience in android and stand in minus on technical aspects. You opinion about letting users do the testing of kernels is kind of valid BUT since IMHO, what spica doing is the right thing here. Since this is a development section. So technically developers release their work here so that others developers can test it and contribute 'technically' to improve their work. Honestly speaking dumbass users like me have absolutely no place here :).

Everyone who uses the work of a developer have to , should and must understand that what he is doing is testing a possible experimental work and it can lead to unpredictable results. Then analyze what happens, look for possible workaround or solution and give it back to the developer and others, to improve his work.

Dumb users like me have no place here because I don't understand what happens if I use a particular switch or parameter. So there is absolutely no point doing something that I have no clue and then come whining and spoil the developers thread with statements like "helppppppp or my phone is deadddd " or similar things, without even bothering to give details like - for example - what kernel they use, what BB / ROM combination they have, What other application they installed that possibly can create this problem.

Having said that, there are a lot of good developers who patiently help people like this because of the goodness of their heart - you are on of such person. Yet, this being a developer's section should not be treated by noobs as a personal helpdesk to get instant technical support for FREE. If that happens, it affect the development very badly because it wastes everyone's time - especially of the developers.

Phew..! Since my rant is over, I will get back to you 'if' I understand what happens after installing your kernel and eagerly waiting for your latest gift to us :D.
[LG Optimus 2x] ryaneu:
There are some users who prefer simple and stability rather than something with many new features but not so stable.
[LG Optimus 2x] spica1234:
Yes you're absolutely right but whats the theory and logic of writing that paragraph in OP thread?

Does it make sense?
[LG Optimus 2x] vadonka:
the difference between the v20l and the v20q kernel is almost nothing.

better off pick any v20l based OC kernels what is tested by the users already

some people believe that the new v20q kernel is have a new features and better stability. i was compared the v20l and the v20q kernel, an other thread im posting the difference and a patch file too. i can say the lg developers did not force themselves.

Can we stay on topic?? Thanks :D
[LG Optimus 2x] Striatum_bdr:
Yes that would be bad to close this thread...... for some words that should never have been written....
[LG Optimus 2x] coldfear00:
+1 for spica, critizing a developer for doing something new is not right IMO. if u want stable then stick to stock.

BTW loving the flaming going on ;-)
[LG Optimus 2x] Lo_RaT_PeNaT:
I do not think anyone has criticized spica, quite the contrary, two different views and equally positive in the absence of our device as usual and once again the LG more interested, however, the thread is to talk Kernel, not if I like something or other but ultimately developers to present their work and the rest to try them. and our opinions to help improve the whole story. Greetings to all.
[LG Optimus 2x] coldfear00:
if u wanna talk about kernels and not personal views about who likes what, then stefan should not have said this line " It's not only the instability of current kernels, it's also the "overkill" especially spica does with his latest RC12 kernel - I prefer to keep things simple, users are users and not developers "
[LG Optimus 2x] spica1234:
Yes :p that's what I'm pointing, on the first page(OP) of this thread, he should write describtion about his kernel like what other dev does, not about what I or anyone is doing:)

Never mind
[LG Optimus 2x] Lo_RaT_PeNaT:
I insist, I think the thread is to discuss the kernel, after each has their opinions, but to make it clear, how about this?

[QUOTE = Stefan Gündhör; 22370651]

Big THX to spica1234 for support supporting me via PM DURING development!!

[/ QUOTE]

You think stefan is being selfish and evil?, I think not, just believe that for most users, and say it clear, most, including myself meeting, we are unable to understand many things, is a opinion, written words can lead to misinterpretations and in this case, I think stefan at no time intended to offend or criticize the work of spica, but good sprucing think they will not be no doubt. In any case I think this should stay and finished, sure everything is clarified and two, two developers, along with others are keeping alive our mobile and certainly is welcome. Greetings to all
[LG Optimus 2x] fajarep:
hi, wow, good luck with the kernel :D i made my non overclock kernel in our local forum based on v20q for stock based rom like gr6...

make sure you got a lot of free time, doing kernel and rom at the same time takes time a looooot.....
[LG Optimus 2x] Lo_RaT_PeNaT:
fajarep should again return to cheer you too .... not it:D:D:D
[LG Optimus 2x] shpapy:
getting back to the topic did some1 actually tested this kernel?
[LG Optimus 2x] coldfear00:
y r u so hooked up on proving stefan innocent, how do u know he didnt mean to critize spica, and y dosent stefan clear the foul air himself on this thread.

im +1 for spica because if my english aint so bad this line he said looks like criticism to me " It's not only the instability of current kernels, it's also the "overkill" especially spica does with his latest RC12 kernel - I prefer to keep things simple, users are users and not developers "
[LG Optimus 2x] Lo_RaT_PeNaT:
for my issue resolved, but absolutely sure that the intention of stefan is not apparently be interpreted, also without a doubt, and now please, to the point, the kernel, and I must say that I tried the BT's car and has not been disconnected at any time, not blackscreen not freezes at least for now the battery issue, I can not say for now. Greetings to all.
[LG Optimus 2x] Scougar:
Thanks Stefan.. you've put much more into this than you intended! :-)

Did you see Spica had recently fixed a cpu memory leak in his HP build that was causing the phone to need a reboot after 100 hours?
[LG Optimus 2x] Stefan Gündhör:
Thx :-)

Yes, I recently saw it, I think I will merge the scheduler memory leak fix and also revert some changes I did to the lowmemorykiller.c file...
[LG Optimus 2x] vpaulve:
Thanks Stefan! I use 1050 MHz only.

[LG Optimus 2x] ninalee123:
Stefan, thanks so much for the strong vibration kernel! (thx to spica too!!) I was really waiting for that one! Just installed it, going to test for a bit and report back.

-Looking back to the day when I first got my 2x... we've sure come a long long way:D

cheers
[LG Optimus 2x] chipper36:
Hi Stefan thx for your excellent roms & kernels.

I always check out your revisions :thumbup:
[LG Optimus 2x] Stefan Gündhör:
You're welcome :)
[LG Optimus 2x] k101d:
Sorry I try to search this thread BUT not found what the different between bulk_noOC_nromalvibration and bulk_normalvibration that I think both are not OC so what better I choose.
[LG Optimus 2x] Stefan Gündhör:
Bulk is overclockable too, the same as AndrevOC edition, the only difference is that the last one will also install the OC/UV tools.

Yesterday I recommended noOC edition, but meanwhile I recommend the overclockable editions :)

Give the AndrevOC edition a try!
[LG Optimus 2x] k101d:
That I follow you said before no OC :D I now I need to download OC :D and also your signature + without ZRam :cool:
[LG Optimus 2x] Stefan Gündhör:
bulk = OC

bulk_noOC = no overclocking

andrevOC = OC + OC tools

:-)

enjoy
[LG Optimus 2x] k101d:
Your signature said without zram @1.0 GHz but first post you said clock step are 216, 324, 503, 800, 1015, 1100, 1216, 1408 so what is 1GHz :confused:
[LG Optimus 2x] Stefan Gündhör:
the possible cpu speed steps are given in MHz -- 1000 MHz = 1 GHz

overclockable kernel runs at max. 1015 MHz by default which is about 1.0 GHz

also the kernel is without ZRam by default
[LG Optimus 2x] GentlyCriminal:
Stefan is fast dormancy disabled with your kernel?
[LG Optimus 2x] Flix123:
Fast dormancy gets disabled with modified framework.

If you have V20q, flash this zip file I made for it:

http://www.mediafire.com/?juj60j4hfijgrxu
[LG Optimus 2x] GentlyCriminal:
yeah I used your tweak pack, but somehow I get a bootloop when I use it with django stock, bulk OC kernel and zram enabler
[LG Optimus 2x] Stefan Gündhör:
Fast Dormancy is ROM-related, not kernel-related. Please discuss this in ROM threads.
[LG Optimus 2x] GentlyCriminal:
I made it anyway
[LG Optimus 2x] kkyoiori2001:
About Zram question

I've search a file named "SWAP 128MB"

Will Zram（+369MB） drain battery faster than +128MB?

or they drain battery same as each other?
[LG Optimus 2x] vpaulve:
I have installed DjangoManouche1.0NoWipeEXT4Gueste.zip + guestekrn_1.3withAndrewOC_strongVibration and I lost GSM signal three times into two hours.

When I tried Antutu i get a reboot into testing.

I have installed DjangoManouche1.0NoWipeEXT4Gueste.zip + guestekrn_1.3withAndrewOC_normalVibration. I have same problem with GSM.

I'm backing to DjangoManouche1.0NoWipeEXT4Gueste.zip + guestekrn_1.2.1withAndrewOC_normalVibration. It works!
[LG Optimus 2x] cmahendra:
great combo

using

gueste2x_GoodBye_1.1_noSwap_Minimalist_smoothScroll.zip

with

guestekrnL_v1.2.1_Bulk_normalVibration.zip

without any other tweak and its working great. No network issue, no battery drain. great combination.
[LG Optimus 2x] Stefan Gündhör:
Thank you! I removed v1.3 and will release v1.3.1 soon! The tweaks have been too agressive, sorry for the inconveniences!
[LG Optimus 2x] feav:
Is there a big difference between 1.2 and 1.2.1 noOC versions? I asking because i have no problem with 1.2 noOC + zram and need your oppinion )
[LG Optimus 2x] vainqueur:
I am using your "guestekrnL_v1.2.1_Bulk_noOC_normalVibration version". So far so good, seems to be quite stable and I am not getting issue with my data plan anymore. I have tried a couple of the oc version from many developers, thing is that, oc is fast but all seems to have some stability problem and in my case, I seems to have data plan connection issue. I don't know whats the difference with the stock rom, maybe I just don't like the lack of smoothness in the stock kernel.
[LG Optimus 2x] Stefan Gündhör:
guestekrnL v1.3.1

extremely small kernel and modules sizes (even without -Os compilation flag) - comparison:

HP SR3 Kernel Image: 3,3 MB

guestekrnL v1.3.1 Kernel Image: 2,2 MB

HP SR3 Kernel Image + 5 Kernel Modules: 11,0 MB

guestekrnL v1.3.1 Kernel Image + 9 Kernel Modules: 2,8 MB

both ZRam (+369 MB Ram) and Swap (+383 MB Ram) enabler/disabler available for download - freedom of choice :-) (ZRam enabler will disable Swap and vice-versa) ; Zram should be more performant than Swap, but eventually also drain the battery faster ; both ZRam and Swap are disabled by default

BFQ scheduler updated

many entries added to global kernel configuration file "include/linux/guestekrnl.h" (only important for users interested in compiling guestekrnL from source)

bug fixes, performance tweaks

compilation flags changed (-O2 instead of -Ofast)

some kernel logging removed

xz-compressed kernel image, xz-(de)compression (boot-time) support added

reverted some changes in lowmemorykiller

many voltage and clock/speed adjustments

new version of ZRam enabler, the old one won't work!

stable, not too highly undervolted kernel -- you can UV yourself using UV tools though (only overclockable edition)
[LG Optimus 2x] Memhis:
Downloaded&flashed from phone at work. New guest kernel and coffe is a good way to start another day in the office :). Thank you Stefan!

Hey,that's no comparison, it was just a way of saying that ur kernel it's a little bigger . U ate both great and do a great job for this comunity. sorry for my bad english :p .

p.s. Can somebody tell me plz how is it possible to make the text smaller in stock sms messqging apk? The text is too damn big with DroidSants. :(

Hi, do u recomend ur 1.3.1 kernel in mix with HP Performance Pack V10R? Is there any changes in performance or something? Thanks in advance.
[LG Optimus 2x] cmahendra:
@stefan

was with your rom 1.1+guestekrnl 1.2.1 (all was working well)

Took Backup.

1) wiped dalvik cache and flashed v1.3.1_withAndrevOC.... phone hanged on LG logo

2) Then again wiped dalvik cache and flashed v1.3.1bulknormal....phone hanged on LG logo again....

Restored back the backup. works fine.

Wiped dalvik cache before flashing kernel as instructed in first post. What might have gone wrong with my flashing? :confused:
[LG Optimus 2x] PG101:
ENOUGH!! Both Spica and Stefan.. check your PM.
[LG Optimus 2x] Stefan Gündhör:
@all: v1.3.1 powersaving version is out. this is my last post on XDA. Development might continue for local forums, if so, you will find the latest kernel in mediafire folder! Thank you for all your support and enjoy upcoming release of DjangoManouche with guestekrnL v1.3.1. Edit: as of the feedbacks

best kernel version is v1.2.1

, because it is performant and also saves battery! So, best try 1.2.1

Bye :)

[LG Optimus 2x] ryaneu:
would you mind sharing what changes you did exactly for the powersaving version?
[LG Optimus 2x] Stefan Gündhör:
Damn I hate leaving questions unanswered if I read them.

How does this look If I post yesterday I won't post anymore and continue posting today as of all the nice words and people saying I shouldn't leave?

It really doesn't look good if I continue posting.

But fortunately I don't care what ppl. think about me so I'll just do what I like to do, and as there are so many nice people around I'll at least continue posting when I have time to :)

To answer you question, powersave version has different speed steps (lower minimal step) and different voltages as you can see in guestekrnL tweak file right under "#ifdef IS_POWERSAFE_KERNEL"

https://github.com/StefanGuendhoer/...-stock/blob/master/include/linux/guestekrnl.h

The reason why v1.2.1 is still recommended as best available version is that v1.3.1 powersafe won't be (and especially scroll) as smooth as v1.2.1 does.

The reason for this is (in my opinion) the intense use of 2nd CPU core in v1.2.1, while in v1.3.1 I reduced it very much. Just to see the results, and as they aren't they best, I'll continue making more use of 2nd cpu core in next kernel version again. Many users told me that consumption in v1.2.1 during use is not bad, and exactly during use nearly all the time both cores are active.
[LG Optimus 2x] PG101:
Gentleman and a scholar ;)

You will be welcomed back :)
[LG Optimus 2x] Lo_RaT_PeNaT:
stefan I have a question quite reasonable and I can not understand what is happening, and discuss it via mp but returns to the subject:

Kernel stock rom civato:

Core 1=1000

Core 2=1000

both cores running at once, making a power of 2000, which translates into greater speed and responsiveness in every way, and the battery consumption is not an exaggeration, but rather a normal consumption

any of the 3 current Kernels, spica, stefan and fajarep

Core 1: 1000

Core 2: Of-line

Total: htc desire, samsung s etc etc,

I do not understand, if this is due to save battery, if so, I would ask a kernel that does not save much, I really do not understand, if the kernel is also OC, we can go at speeds well above, I have the feeling sometimes that rather than a dual core and I have a single core is not really taking advantage of the power of something you have in the phone, sure it has some explanation, but I really escapes me. a greeting
[LG Optimus 2x] Stefan Gündhör:
With v1.2.1 second core is turned on very soon and running very long. But as other DEVs kept saying that so much 2nd core is no good for battery I tried making less use of it in 1.3.1 and in my opinion this was a big mistake. The difference in battery isn't really measurable for me and the smoothness especially in scrolling has decreased.

These few lines make the difference --- 1.3.1:

/**
* Defines CPU frequency threshold for slave CPU1 power management:
* - CPU1 is turned Off when cpu clock is below ON_MIN for
* ON_PENDING time in a row
* - CPU1 is turned On when cpu clock is above OFF_MAX for
* OFF_PENDING time in a row
* If thresholds are set to 0, the values are derived at run time from the
* characterization data
*/
#define gueste_CPU1_ON_MIN_KHZ	800000	// orig 0
#define gueste_CPU1_OFF_MAX_KHZ	950000	// orig 0
#define gueste_CPU1_ON_PENDING_MS	2500	// orig 2500
#define gueste_CPU1_OFF_PENDING_MS	1000	// orig 1000

vs. 1.2.1

/**
* Defines CPU frequency threshold for slave CPU1 power management:
* - CPU1 is turned Off when cpu clock is below ON_MIN for
* ON_PENDING time in a row
* - CPU1 is turned On when cpu clock is above OFF_MAX for
* OFF_PENDING time in a row
* If thresholds are set to 0, the values are derived at run time from the
* characterization data
*/
#define gueste_CPU1_ON_MIN_KHZ	800000	// orig 0
#define gueste_CPU1_OFF_MAX_KHZ	503000	// orig 0
#define gueste_CPU1_ON_PENDING_MS	6000	// orig 2500
#define gueste_CPU1_OFF_PENDING_MS	10	// orig 1000

And on stock kernel 2nd Core will be turned on after being 1000ms over 2/3 of max. Speed (1.0 GHz) and turned off again after being 2000 or 2500 (don't remeber exactly) ms below 1/3 of max. Speed (1.0 GHz). So even on stock it will kick in earlier and last longer than on latest kernels. But 1.2.1 should do it for you, there 2nd Core will run most of the time when using your phone.

Also, in general on all current kernels 2nd core is used after a while of heavy cpu load, because otherwise you would get Antutu results of about 4xxx points @ 1.2 GHZ after a fresh reboot and instant Antutu test. (this is what I got when I tried it with one core completely disabled) As soon as you reach over 6000 points @1.2 GHz you can be sure 2nd Core is running, at least after a while.
[LG Optimus 2x] Lo_RaT_PeNaT:
I understand what you say, and I'm grateful, but I thought that making the kernel OC, was to increase the yield and reaction applications, believed that with two cores, this would be ideal, however, I see a problem battery is preferred to use a single core for most of the time, I think that at least could get a kernel to 1.2, for both nuclei, galaxy type s2, but I see that we have to make do with what there is, thank you very much for the explanation .
[LG Optimus 2x] Stefan Gündhör:
Please try...

Non-overclockable version of guestekrnL will be continued separately under a new name (QuickStock kernel).

The only three important things of QuickStock kernel are maximum (scrolling) smoothness @ maximum battery service lifetime & maximum stability.

There won't be a possibility to OC or UV. (but there will be new versions of guestekrnL with changes merged)

Currently ZCache and ZRam both are enabled in the kernel (though there is a version without ZRam too). Please try the enclosed files and report about the battery drainage - without feedbacks there can't be improvements ;)

Version without ZRam should drain less battery, but still ZCache is enabled in both.

If battery drains too fast, I will disable both ZCache and ZRam.

Full changelog will come once the kernel has been tested by you and I can release it as final.

Edit: removed, because obsolete :-) (the kernels are not bugged though, so you can keep using the prereleases if you want :-) )
[LG Optimus 2x] carburano:
Trying :)...
[LG Optimus 2x] Stefan Gündhör:
Thank you :)

Well ZCache isn't working yet unfortunately (will try to fix).

But ZRam with newly introduced "Snappy" compression does.

Also, I'm not satisfied with scrolling smoothness of "QuickStock" yet.

I'll continue with releasing a test-version of guestekrnL v1.4 first (OC up to 1,5 GHz). Writing detailed changelogs as soon as released and I have time to. You can be sure there have many things been done and still will be done :)
