Hey guys, I'm currently using the stock kernel on the new base vrall4. I was just wondering, is there anyway to get more governors because in setcpu I only have powersave, performance, pegassuq, userspace, and ondemand. I'd try a new one but I heard stock was better with the new base.

You 'heard' it was better with the new base? Just try out the TW custom kernels if you want more governors. You won't be able to get more governors on the stock kernel unless you're some sort of kernel developer. It never hurts to get out of stock and try something custom because most of the time custom built roms/kernels are better than factory stock.
The best choice at the moment is Saber Kernel. You can have Interactive, Lulzactive, PegesusQ, and others.

Thanks man. I'll look into that one. The only one I knew of was the perseus kernel

Hey guys, new to the forum and the Vibrant, and i first want to say i love the setup and this forum is insanely informative on its own. Im fully rooted/themed/tethering/modded and the only question ive had to post was about icon .png size haha. so thanks for setting up a VERY efficient forum.
now my question: do i have to install a custom kernel in order to overclock/underclock? I installed setCPU and it wont let me scale past 800mhz. Also no presets, its just says to use conservative scaling for GalaxyS phones. No thank you, i wanna push this thing! Running stock kernel and firmware. Thanks ahead!
I believe you will need to flash one of the many kernels that fits what you want it to do, you should be able to under clock android if your phone is rooted but you will need a new kernel to overclock it.
when you install setcpu make sure you do auto-detect. since you already have it installed, hit menu->device selection->autodetect speeds
on a stock kernel you should be able to set max to 1000000mhz. With the Vibrant ALWAYS LEAVE SCALING TO CONSERVATIVE or you will have freezes.
To get past 1000000mhz you will need a custom kernel, I have been happy with both King's and JAC's. Just download one of their kernels, flash it through CWM, reboot, and run setcpu again and make it autodetect your speeds, from there you should be able to clock up to 1200000mhz
Good luck.

I'm not very familiar with kernels, so naturually im a little hesitant. What else will it affect?

It all depends on the kernel you flash. If you flash voodoo it will change the way the phones file system works. However if you just flash JAC's OC/uv kernal it will OverClock up to 1.2 ghz and UnderVolt some of the midrange frequencies to help improve batterylife. I reccomend reading up on his threads before you attempt these flashes. He has made the procedures to flash these kernels very easy to implement. Good luck and happy flashing! (That just sounds wrong!)

Moved to Q&A
hello,
I'm using the official lg rom v2.2.1 that came with the phone. I wanted to update to cm7 but I read about the problem with the BT wich I must have. another thing is that I'm using hebrew and I need it to stay that way.
The thing is that the touch screen is very bad and lags a lot.
If I will upgrade only the kernel what will be the affect on the phone and how do I know what is the best kernel for my version ?
In general I want to fix the touchscreen bug and to OC the phone.
thanks for the help.
If you just want to overcome the touch screen bug then I would suggest using Der_Caveman's Kernel, it is quite old but is usable and removes the touch bug and enables OC.
The kernel wouldn't change any outward appearance of the phone, except maybe increase the quadrant score a bit. If you really want a good performance boost as well then try franco's kernel. Since you are using the stock rom it is recommended to take a nand backup before flashing these kernels. And a kernel doesn't change the system language AFAIK.
Thanks for quick reply. will these two kernels good for froyo 2.2.1 and are there known bugs that I should be aware of before updating ?
As far as read the franco's v18.1 is for 2.3.3...
I have never used Der_Caveman's kernel, but it is bug-free AFAICT. And in the link that I have posted above, franco kernel is available for both froyo and GB. Download the version that says "franco.Kernel v8.1 CFS", it is for froyo.
And as I said earlier, since you are on stock rom it is advisable to take a nand before flashing a custom kernel.
i used dookmatt's kernel which was really good for me(flashed it on stock 2.2.2)...i had no touch lag, no bugs. that would be my recomandation
also dont forget nand backup is holy!

Can I OC with this one ?
OK, I flashed Der_Caveman's Kernel and so far it looks good. the touchscreen is better and I OC to to 729 using setcpu though I cant tell the difference in terms of the speed.
how can I tell if its really 729 and not 600 ?
thanks.
yes my O1 ran at 787 mhz and it was darn stable(at 800+ i had frequent freezes and reboots when launching apps). i also had a friend of mine install this kernel and he's happy with the "new" phone i made
quick system info on market...shows cpu speed
You may look at info tab on SetCPU, it says alot about your device, CPU (frequencies and features), battery and so on.
And you can have SetCPU widget on homescreen as well, which shows current freq, min and max frequencies of the governor you're using
Regards
can i use the faux kernel with the stock rom with the latest OTA? Which advantages i gain? Thanks
If by stock ROM you mean AT&T 4.5.9.1, then yes you can use his kernel. The main noticeable advantages are the ability to overclock and undervolt. Other than that, there are some tweaks to the code that also contribute to improving performance.
I would only flash this if you really want to overclock your phone though. If not, stick with stock -- the phone is fast enough as it is.
Hi, I've just a quick question regarding kernels (in general)
I'm currently running a JB ROM by TheBill, and it's running great. However, coming from my previous phone with a custom rom, I see there aren't many governers available. I would think that a custom kernel would do the trick, but would they work regardless of rom/OS version? Most of the ones I see seem to be for Gingerbread/Froyo, and I'm with Jelly Bean.
I didn't try this so I am not sure, but I think that kernels have their compatibilities with rom. So whatever kernel you are going to flash just read the kernel's details. Then you'll know what roms (cm7,cm9,cm10etc.) it will support. And I hope that you know kernels are phone specific.
Atrix 4G, CM7 based TopSmarts 1.3 rom, Faux123 1ghz kernel.
If I m helpful dont hesitate to thank me.
Don't try to mix and match kernels unless you know what you're doing. It will probably not work as expected, very likely not at all.
There's probably a reason for the lack of governors in some kernels, don't you think?

Well I'm running CM10 and it seems like most of the kernels haven't been developed specifically for 4.1, which is why I brought up the question.

Well, I was wondering if I could get a bit of a power boost with a kernel supporting overclocking, but if I do try and install a kernel that doesn't work out, a Nandroid backup should restore my previous kernel as well?

Yes, Nandroid backup will restore your kernel.

I'm using a stock based ROM (I think), it's the simplicity one, my question is, is there a kernel I can flash so I can overclock or underclock the CPU? Also, will I have any bugs if I change the kernel?
Thanks in advance.
No kernel for our device can overclock till now, but all of them can however underclock.
Except the CM specific kernels, all kernels in our section will work on simplicity or any other stock based ROM.
For bugs, you'll have to check the OP of the kernel you want to install. There are hardly any bugs btw.
