As you have probably heard, the 2.3.3 update for the Nexus S sort of calibrates the screen. I am one of the few who has every tv in the house professionally calibrated, and sAMOLED has a ton of issues with over-saturated colors, too cool of a color temperature, red or purple grays at lower brightness settings, and the grayscale is off. Is it possible that these calibration tools can be ported to the Fascinate, so that it will have a more calibrated screen? I would love to get rid of the purple tinges to certain shades of gray at low brightness settings.
Bump. Anyone?
Supercurio has a color fix in his Voodoo package, but it can't be applied to the Fascinate Froyo leaks, because we don't have the kernel source code necessary to make the modifications. It was implemented on the Eclair Voodoo kernels, and will be applied to Froyo and Gingerbread roms in the future once working source is available.

Yes, but it was only at 100% brightness. Either way, I wish Samsung would hurry up with Froyo and the source code. I know it was tweeted that it is coming, but I am starting to doubt that.
If you follow supercurio on twitter, you'll see that he has been doing QUITE an extensive amount of research into color calibration on the Nexus S, and will likely be porting all fixes to the Galaxy S series as well. The color fix is not a finished product, but rather a work in progress.

Since the vibrant doesn't have any kind of LED notification, I was wondering if it was possible to use the 4 bottom keys as a substitute. I found an app called NoLED that displays notifications on a black background (and since all galaxy phones have SAMOLED screens it wouldn't use much power), but having one of the 4 bottom icons light up or flash would be really cool.
I remember reading somewhere it was all or nothing As far as turning the bottom lights on...buy don't quote me.
Another thing to note us that black on the screens uses no power.

so i read into this a little more and it seems like TW made a kernel for this (i found the info on their forum). For those of you who are interested, its called BLN (BackLightNotification) and its in some of their kernels (DoW 1.3, 1.4, etc.). Does anyone know if this is available for the vibrant yet?

Yes it is available for the vibrant but the kernel of the rom you are running must support bln...like DoW...
Sent from my XDA app cuz I'm stalking your mom....
also know that kernels with BLN support are all i9000 ports at the moment.
Pros: You get BLN fucntions
Cons: Quick battery drains (8-12hrs off charger at best)
$0.02, id rather check every now and then by turning the screen on than sacrifice 40-50% battery life.
Alright, so I've been rooting phones for about a year now, but I have zero experience with the Fascinate (have worked on Eris and DInc before now) and my buddy wants me to help him root his phone. I've been reading for a while now, and there's one thing I haven't been able to figure out.
What is the deal with Voodoo? Is there an appreciable difference in performance between a non-Voodoo and a Voodoo kernel? Are there drawbacks to either?
Thanks in advance for any help.
Voodoo is code that is developed by supercurio. There are many branches of voodoo, including color, sound, and lagfix. Each aims to improve upon what Samsung has given us.
Color improves the color contrast of your screen if it is too blue or too red.
Sound is a fix that utilizes the driver inside of our phones to improve gain and give us new options
Lagfix converts all partitions from samsung's rfs file system format to ext4 and yields speed benefits
I am not 100% that my terminology is correct. Please correct me if anybody sees something is wrong.

IMO, voodoo is the only way to go. It is an overall improvement of your phone experience.

So Voodoo kernels contain one or more of these fixes?
Voodoo is basically the conversion of Samsung's RFS file system used in the Galaxy S phones to the more native EXT4 file system.
It also contains improvements such as color, sound, and such.

Nice. Thanks for the info guys.
So are there any drawbacks to using a voodoo kernel?

The only drawback that I have found is that given the slim amount of ROMs we posses here in the Fascinate community.... running a voodoo kernel can limit that a little more.
Also usually when updates roll out from source voodoo takes a little longer to come out.
But in all honesty there is very little in the way of drawbacks. Plus if you don't like it? Flash a regular kernel!
With the recent editions of Voodoo Color and Sound I would see even less reason to not use it.
I think source was released for the i9000's (not sure) 2.3.3 and if that is the case, I thought we'd start seeing work on 2.3.3 kernals with mods like BLN etc brought to the Vibrant.
Are some required ingredients still missing to do that kind of work, are we still waiting on something to get released before that work starts, or maybe the roms have work required before they'll start on the kernal. I'm not impatiently asking for the work to be done at all, I'm curious if the pieces are available to devs yet so that they can work on it.
Thanks for any input if you know what's going on. If you don't know then, well, go ahead an do what you do best.
From what I've been hearing from ttabbal, it seems that Samsung changed the way to gpu loads up by using the bootloader.
What this means is that, without a vibrant gb specific bootloader update (not and sbl.bin, but a boot.bin), then we will only have software rendering in everything graphical, and now viewable recovery screen.
And also, it's kernel, not kernal.

Very informative amigo, thanks. So the rom will have those gpu issues and now a lot of the graphics stuff makes sense. It's funn that using 2.3 is in many? ways a step back in optimization right now instead of the step forward we hoped for like the nexus S #wishfulthinking
I still wonder if we have the capability yet to implement BLN, I enjoy having that and I guess CM7 has kernEls with something comparable so I could always go that route and specially since it sounds like CM7 has been smoothed out a lot.
I'm actually running CM7 right now and it's pretty smooth. I don't think I'll be going back to 2.2 on this phone unless something huge is offered.

ive tested pretty much all the kernels that xda has to offer, and i'm still bouncing back an forth between CWkernel and Tigers Blood FPScapped.
I'm one of those unfortunate souls that have a Vibrant that doesn't like the FPS being uncapped...and it gives me the shaky screen thing upon boot. No Bueno.
I just want a kernel with good performance, BLN, Voodoo Sound and color, and reasonable battery life. CWkernel provides this, but doesn't seem as smooth as tigers blood...plus Jocelyn no longer supports it.
with tigers blood, i get more of a battery drain than CWK.
I would also like a less invasive Kernel Screen like the B&W "google" that Jocelyn has put in CWkernel.
I would do it myself, given the knowledge....
Could someone point me in the right direction as far as compiling my own kernel? or at least suggest one other than the two described above?
Thanks!
To clarify, are you just looking for a guide to compile a kernel? Or do you need a guide which includes instructions for applying Voodoo, BLN, etc. and then compiling a kernel?

Ive just used overstock and bali kernel but I didnt saw that on the descriptions (or dont remember)
Give the Bullet Kernels a try. I think you will be intrigued by the raw speed and good battery performance.
So I'm sure the title makes this clear already, but I have an HTC Incredible as of now, but am preparing to trade for a Fascinate. From what I've gathered online, the Fascinate has the Incredible beat on hardware (except for the camera), but isn't quite up to par on software (TW vs Sense, Bing, just got Froyo, etc), but for a CM/AOSP guy, that's not too big of a problem.
So, I just have a few questions as I prepare to make the transition.
With the DInc, pretty much everything can be done on the phone after the one-click root with unrEVOked. It's to my understanding that much of what has to be done is in Odin? The concept of going through another technological medium to accomplish something on my phone is going to be a bit new for me, but I catch on really quickly, so I'm not too worried.
Are there any tricks or tips/helpful reading material that anyone could suggest as I settle in over here?
As I looked through the Dev section (however briefly), it seemed like Kaoscinator was the most stable GB rom available on the Fascinate. If this is not true, which is? I'm not a fan of MIUI, and tend to like stock GB (or as close as possible) the best, so this would really be my biggest question.
Thanks!
The stickies in the General section should get you off to a running start. As for CM/Aosp builds, JT's CM7, currently test build 5, is the most stable and functional at this time.
i would suggest ComRom, most AOSP like in that it doesn't have TW, but everything works, give CM a alittle time, it will be perfect when 100% working...but also know that OMFGB and OMGB will be ported soon, r2doesinc is on the case, and they are working on that atm...
I ended up going through ComRom to get to the CM7 alpha/beta/whatever it's being called. It's pretty stable, I was pleased with it. I needed me some real AOSP though (modded AOSP, but you get the point). The only issue I've had so far was the random ringing, but that disappeared after someone called me before I had the chance to reboot. Haven't had it since.
I was having problems using RM to flash a recovery, but that's because there was a step that I was skipping... Odin. If my bootloader had security disabled, S-Off, I could completely unroot, and go from pure stock to a rooted Rom in the time it takes to make a Nandroid, wipe, flash and boot. Being able to flash a recovery image through the bootloader on the phone is really the only thing I miss from the Incredible other than tthe optical trackpad. I'm loving the screen size, and everything else. The processor on this phone is fantastic. I can't wait to see what springs up in the development forum once the CM team officially supports this device. Especially some OC kernels... this thing could go even faster, I can feel it.
OMFGB will be a welcome addition as well. R2 and his team do great work!
I'm still learning things and establishing procedure, but if anyone could point me to some plain as day information on what exactly Voodoo is, that'd be great. That's not something I've ever heard of until now.
Thanks for the patience! I catch on quick, I promise I don't ask a whole lot of questions, as I try to figure it out on my own first, the switch is just a little daunting with the addition of Odin. Weird stuff.
Voodoo is comprised of a few parts.
Voodoo lagfix-- converts the file system from RFS to the speedier ext4. This improves the responsiveness of the phone
Voodoo Color-- makes the colors of the phone "pop" more and look better.
Voodoo sound-- The galaxy S series of phones have a VERY good audio chip. Voodoo sound lets you fully take advantage of the processor's power. Hook this phone up to a decent receiver and speaks and you will be pleasantly surprised.
Voodoo sound and color REQUIRE kernel source code to be baked in. Voodoo lagfix does not require kernel source. Thus, you can have voodoo lagfix without color/sound (and potentially vice-versa).
Aha! The Fascinate's partitions ARE Ext4 (except for non-Voodoo, of course)! I thought so! The partitions were all Ext3 on the DInc. That's pretty cool!
Now, how would one control Voodoo? Is there an app that does that, or is this controlled via the Voodoo Settings in the Lag-Fix Recovery?
Sound is controlled with voodoo control app in the market. Lagfix is controlled by clockwork. Color is just built into the kernel and has no setting options
Voodoo color only works when you have your backlight set to max brightness... unless I am mistaken

You are correct...its to help balance the colors to remove the blue tint of bright white display due to its pentile design

Yup, I just found that exact kernel. I stumble into something new every time I go through the Dev forum. I'm definitely digging this phone.
