[MENTION=2677519]mathkid95[/MENTION] I am having some sort of touch_boost problem. Whenever I touch the screen iI can see this message repetitively in the logcat:

02-18 03:02:57.782: E/PowerHAL(583): touch_boost: failed to send: No such file or directory

Can you please look into it? I wanna see if it's just me or a problem in the kernel itself.

Thanks in advance :)

I know this has been asked before and I'm sorry for asking but how exactly do we implement this color pro in trickster or fku? Or where is it that I place the file? Thanks
[Nexus 4 Original Android Development] arffrhn:
Place the file in /system/etc/init.d. Then set the permission rwx, r-x, r-x and reboot. That's it.

OK and this sticks after boot? Does trickster conflict with it?

Whats the right permission on init d scripts isnt it rwx rwx rwx?

[Nexus 4 Original Android Development] arffrhn:
Well, just don't change gamma settings in trickster. If you play with gamma in trickster and set it on boot, it will override the init.d as init.d is triggered first before trickster set.

Just open the init.d folder and see the permission for the scripts inside. Set it the same as those files. It should be rwx r-x r-x.

Thanks for your work however the lowest frequency is retained too aggressively. Try streaming internet radio with Tunein and you get horrible interruptions (when the screen is off) every few seconds. After a lot of trial and error I used trickster mod to increase the minimum frequency to 288 and mostly the problem disappears (rarely it still happens). Also what is the recommended kernel governor, is it on demand or interactive? Thanks.

EDIT: Problem is not solved and I have moved to a different kernel which works perfectly.

regarding the color profile mentioned by :themike10452

http://xdaforums.com/show...postcount=3008

is it possible to put these values using trickster. I was playing around with different kernels. Script worked fine when using Matrix, but showed error when using Semaphore kernel. /sys/devices/platform/mipi_lgit.1537/kgamma_r etc file not found
[Nexus 4 Original Android Development] themike10452:
Semaphore uses it's own gamma format. My script only works on kernels using Faux Gamma.

You can set the script on matr1x kernel, then go into trickstermod and save the presets, then go apply it on other kernels.

[Nexus 4 Original Android Development] mohitgalaxy3:
Semaphore has a diff gamma format so probably kgamma_r file is not getting created at all.

Once I will try semaphore, I will try to make the same color profile for semaphore as well.

Anybody played Asphalt 8 with Matrix 13 ? It gives stuttering a lot. changing to stock fixes it and coming back again gives the issue
[Nexus 4 Original Android Development] aymnahmd:
Hello,

This question might be noobish ,

How can I use the stock color profile, because iphone 5 color is too bad for me.

Also the max screenoff frequency, is it applied automatically by flashing the kernel ? Or should i do further steps ?

Thanks for such great kernel
[Nexus 4 Original Android Development] RealSlimShadyMC:
Use trickster MOD to set colours to stock (or LG, which has nicer whites) and the screen off is auto applied
[Nexus 4 Original Android Development] aymnahmd:
Thanks very much

That really helped me.

If you wanna set it using trickster MOD, try this:

color calibration

Gradient Tuning

from lower to bottom half 2

0 0 0

0 0 0

Of course this only works with kernel that comes with faux gamma tuning. I do remember however that there is a way to convert the faux gamma settings to the format that semaphore is using, but I can't find it atm.

hi guys

i've one problem..

gpu is always on high frq on this kernel.. (320_400) how can i fix this..

and i've one question:

when i flash AK kernel it has better pinch to zoom.. starts to zoom faster.. in this kernel (like stock)

my finger must move a certain distance then zooming starts..

Either ondemand or wheatley, it's best to try them both over a few days with your usage. Lower screen brightness will save more battery than the governor, though.

Just went to 150 on v3.0. Seems stable so far but haven't really stressed it much yet. I'll give it another day before reporting back.
[Nexus 4 Original Android Development] Stryder5:
v2.5 caused my phone to crash when bluetooth was connected and playing music to my headphones.

v3.0 was initially undervolted by 100, and I undervolted by another 50 to match v2.5. Bluetooth plays music fine while running Antutu benchmark. Odd, but everything seems stable. I wonder why that's the case.

I assume to undervolt, I just go to System Tuner > Voltage, then tap -12.5 four times to get the extra -50? Just wanted to confirm I've actually been undervolting it.
[Nexus 4 Original Android Development] bigmase521:
Interesting that you couldn't get -150 stable on 2.5 but can on 3.0. :confused:

To answer your other question yes that's correct. I do the same but an extra -100 and I use Trickster Mod instead of System Tuner.
[Nexus 4 Original Android Development] whittikins:
It depends on what your device is set to stock. There are 3 voltage tables because different phones can volt lower at the same speeds. Check motley's thread for info on this. The "slow" chips have 1500mhz set to 1250mv, "nominal" chips have 1200mv, and "slow" chips have 1250mv (as stock).

Thanks for the link, I didn't see that before. Looks like my nexus 4 is a fast chip as on this kernel with out undervolting it it 1050mV@1.5ghz and at stock voltages on flaux it is 1150mV. I can under volt in total -162.5 (1.5ghz @ 987.5mV) at the highest couple of frequencies and 225mV on some of the mid. I wonder how low I could go on the lower freq if the lower voltage regulator was lowered. :) First time having high quality chip, both my int s3 and n7 SoC variants are average. :)
[Nexus 4 Original Android Development] undercover:
How low can you go on 1.5?
[Nexus 4 Original Android Development] Stryder5:
After putting on v3.0 and undervolting an additional -50 (total to -150), I'm now at 1000mV for the 1.5ghz. So does this also mean I have a faster chip?

Also, I tried undervolting an additonal -12.5 all around and got a reboot almost immediately haha.
[Nexus 4 Original Android Development] undercover:
No, I'd say you have a lower one since you were able to undervolt that much. Faster chips default to lower voltage so they can't undervolt that much. I'm still looking into it, I only learned about it 15 minutes ago so ii could be wrong. :D
[Nexus 4 Original Android Development] danielsf:
Hi, I get to 987.5mV at 1.5ghz. I have been at that for a few days with out any lock ups. I may try to go a bit lower soon. :)

[Nexus 4 Original Android Development] undercover:
Really? Did your one say FAST? I wonder which is faster now, FASTER(which could be faster than normal or faster than fast) or FAST. My voltage was at 1150mV I think. - 150mv takes me down to 1000mV on 1.5ghz

45-487MHz is the desired range for Adreno320 performance, it might give you a better frame rate but the best way to improve performance is to go to dev settings and enable force GPU rendering, no major battery impact either
