Re: [KERNEL][GPL][N4] franco.Kernel - r83

Hi, sorry if this question has already been asked, but desktop version isn't working right now so i can't use search...

I love Franco's kernel, but the "contrasty calibrated" colors of PA kernel ate extremely beautiful...

So i want to ask, can i set the values of PA kernel to this? Also (sorry if this sounds a bit ignorant) but i haven't used Franco's kernel for some time. Can anyone tell me if this kernel also has custom colors values or is it stock? Thanks :)

Re: [KERNEL][GPL][N4] franco.Kernel - r83

Not a battery enthusiast, but is this battery consuming pattern normal given I'm on fresh install of PA Feb 18 ROM + Franco kernel r83? I'm a light user and this is the first day I did the fresh ROM install.

There's a "Franco default" that is set to Obasnity's values. There's also a stock setting. If you don't like either of those, you can tweak gamma yourself, providing you're on 4.2.2.

Re: [KERNEL][GPL][N4] franco.Kernel - r83

sorry if this is a dumb question, but what are you guys using to see the values produced by your gamma settings? like, I'm getting 2.2 for grays...where do you see the 2.2? thanks.

So here are the final settings from my side :

RGB 255

grays 0

mids 119

black 119

contrast 12

brightness 2

saturation2

white 0

rev 11

I have adjusted the values as close as possible to my monitor using this yoda wallpaper.https://www.box.com/s/pv6yh43ohqo1vsl6558q

The calibration should be such that the glow in yoda's light saber should not have any artifacts or distortions.It should be a proper smooth glow. :)

Hope you like it.

[Nexus 4 Original Android Development] bradm23:
Re: [KERNEL][GPL][N4] franco.Kernel - r83

Download an app like better battery stats and look for wake locks. I am running xylon and on hspa network and have 4 hour up, 1 hour screen on time with 83% left.

I bet Google maps is keeping it awake. If you do not get a location lock on after a fresh install it will hold your phone awake, make sure it's not on Wi-Fi either when u get the lock on
[Nexus 4 Original Android Development] Archmag3:
yes thats the way it works :) so basically anything ahead of 119 is equal to 119

Hey Franco. Long time no speak.

I've finally caught up with the latest releases and I have to say that I love r83 :good:

You've been hard at it, obviously. :)

I have a query, that I've been running through various devs regarding HDMI and Slimport.

Basically, I have a Slimport connector which worked just fine with 4.2.1 and since 4.2.2, HDMI output doesn't work anymore. Upon connecting my device to my TV, my TV's screen turns blue and my device crashes. It loses all functionality and I have to do a hard reset to get it up and running again.

The phone crashes, so I'm unable to obtain a last_kmsg or any other kind of logs for that matter, but was wondering if you might look into the situation?

The same issue runs through PA Stock Kernel and Harsh, as well as Franco. I'm pretty certain those aren't the only 3 kernels either.

Did Google f*ck up? - As I said, 4.2.1 was working great. 4.2.2, nothing.

As always, many many many thanks! :o

You'll need to buy the updater. The display app has nothing to do with kernel. The gamma control is through the kernel, which is why it's only through the kernel app.

R83 absolutely butchered my battery life. I lost 20% just from listening to music for 50 minute with the screen of the entire time. I switched back to the cm10.1 stock kernel and the drain stopped.

Mids: 5

Black: 87 (you can go up to 119 but in photos it saturate the shadows)

No custom kernel settings. Display is auto. Well I only had two hours of screen on time, most of it was either texting, web browsing or groupme. I also had about 40 minutes of talk time. Gmail is my only sync. Location services are off, and don't use Google now. I do go on facebook every now and then, but that app drains your battery no matter what setting you have it on. The other day I had close to the same results but with an earlier kernel build, but instead of finishing at like 50%, I was around 40% just because I had Facebook on sync.

Edit: I also spent, 3 hours in a movie Theater (The Hobbit was AWESOME) and like 4 other hours at the mall with no WiFi. So I did have some "real" world use on it, I wasn't just sitting at home leeching off my WiFi.

Just to inform you that there's literally no way of obtaining a log for this anyway. The Slimport adapter has a port for HDMI cable, a cable that plugs directly into the device and then a port for a USB cable/AC Adapter. However, when I set everything up and connect my laptop to Slimport, it won't recognise the device as a 'storage' device and won't recognise ADB for the device.

Even if I try connecting up my device to my TV and then disconnect everything and just try connecting my device to my laptop as just a single connection, the device isn't responding at all, so my laptop still won't help with obtaining a log.

There just really isn't any way of finding out, as I'm already connecting my device to an external piece of hardware.

I don't know if this'll get fixed in the future, by yourself, another dev, or Google. It feels so much like my Galaxy SII days when I was using CM9/10 and they didn't have the TV-Out working due to lack of source code. It absolutely sucks to be honest.

...but hey, that's life!

I'll make other N4 devs aware of the situation, so that there isn't a bunch of people complaining about the same thing, over & over.

I think a lot of people are maybe too focused on gamma 2.2, but the two photographers' settings do look pretty damn good at 50% brightness. It's pretty clear the Nexus 4 is very contrasty, and if you look at whites, it's very easy to clip at RGB of 255/255/255. Remember that Gamma tests are only one test you do to calibrate your monitor. There's a boatload of other tests.

[Nexus 4 Original Android Development] Ok_Kaleidoscope5109:
edited my post to mention 50% brightness. If you run at 50% it's great. Autobrightness is always tricky because it throws off colors. Remember with monitors, there's no autobrightness and the backlight stays constant, but with phones, having an autobrightness curve will throw the calibration off. That's why they calibrated at 50%. Once you flip autobrightness back on, your indoors brightness is often like 15-20% only.

To compensate for the dark screen, you can up your autobrightness curve a bit (CM 10.1 has that adjustment feature now). Bumping it from 8% to 12% does wonders for the lowest level.
