Hi Everyone,
As the thread title states, I'm currently using an OC kernel (Flippy's 1.9GHz, to be exact) and I'm noticing that I have to press the power button many times in order to get the screen to turn on. Does anyone know why this happens? I asked in the kernel thread and someone replied that this happens with all OC kernels, although no explanation was given.
I also read that this issue may be due to the screen off frequency being set too low. I currently have that set to 768MHz and this should be sufficient given the Desire Zs normal clock of 800MHz.
Does anyone have any insight about this? Thanks in advance
I'm using a pershoot OC kernel and haven't met that problem yet. My cpu is set at a 386mhz minimum. Try Pershoot?
Make sure that in CM settings, screen on/off animation is turned off.
From what I can recall, its a problem with a combination of overvolting the CPU for overclocking, and having the animations turned off that results in not enough voltage to turn on the screen.
CPU stepping is also related, so you can try changing the governor and see if that helps also.
This is a common issue, and has been well covered in the CM7 thread, so just do a search in that thread for suggested settings.

Thanks for replying I've disabled the screen on/off animations and the screen wakes up with no issues now.
Hopefully this issue will be fixed soon as I'm missing those animations already!

So i just swiched from virtouos ROM (sense) to CM6.1 and i am having a problem.
when i first flashed virtouos, sometimes my phone screen wouldnt turn on with
first attempt but after setting profiles on setCPU it was fixed and didnt happen anymore now with CM6.1 i am having a slightly different problem the screen doesnt turn on when i am receiving a call (it rings though) and i have to press the power button couple of times to get the screen on. i have already set some profiles on setCPU ,i am just wondering if there is any fix for it ?
Thanks
Only thing anyone can probably suggest is turning up your min clock speed. What are your profiles set to?
My screen off is 245/368 just to give it that bit extra to guarantee no wakeup issues, not that I had any to begin with, better safe than wanting to throw her up the wall (I get annoyed easy).

Doesn't sound normal... did you make ANY customizations at all? Or did you install CM straight up and just use it like that? Any adjustment to "performance settings" or CPU clocking? What SPL and radio do you have installed?

no i didnt make any customization its just CM6.1 although my max clock speed is at 1497 mhz
setCPU
Screen off max 368
min 245
and profiles for temp and battery as well
the wierd thing is it doesnt happen at all when im just waking the phone up it only happens when its ringing i am thinking its my CPU issue ,i dont think it handles overclocking well ,i couldnt go over 1.1ghz (it would freeze instantly) with virouos that was the main reason i switched im gonna play with with cpu profiles for a while and see if i can get it fixed.
btw i have never flashed any radio so im guessing its the stock one
wow this is very intreasting its actually fine without any setCPU profiles
i had something totally different in my mind.

With my experience I've noticed the phone runs better, and lasts longer on a single charge WITHOUT setCPU profiles. Just my opinion

Is anyone using SetCPU with gingerbread?
I'm using GingerVillain 1.5 but I can't seem to find the right profiles with SetCPU.
Oc'd @ 1,2 Ghz without profiles.
Because when I use the screen off profile, my screen sometimes won't turn on.
Screen off - min 245 max 1200
Can someone help me finding the right profiles?
Share your user experience.
In my experience and many others too, the profiles are not needed. The only profile you should ever need is a temperature profile and that's only if you really have it cranked up.
Having a screen off profile is always bad since switching to another profile doesn't happen instantly - there are polling intervals involved and until the next cycle runs your phone will still be using the screen off profile. That makes the phone slow which causes SetCPU to take longer in switching profiles, bogs down the cpu and it becomes a vicious cycle for a few seconds (sometimes a couple minutes). All the while it's draing your battery because the cpu has to work harder. Even regular profiles eat the battery due to the constant querying of the systems status and processing power used for that - which is the main reason you'll hear people whining about their battery life (some aren't effected as much).
Profiles are just not a good idea except for a temp profile for those that oc to the higher GHz (probably 1.4+).
You could try using cpu tuner instead. Gives you way more options.
CM 7
You have a lot of options with cpu tuner.
What triggers and/or profiles do you use?
My screen on/off has been working fine with CM7 nightlies before and after the RC1. I've been using SetCPU with a normal profile of 1017max/245min and a screen off profile of 365max/245min.
I think your issue is with overclocking. Idk about Gingervillain but as far as CM7 goes lots of people are having issues with the on/off animations and wakelock issues when overclocked over 1ghz. Try using your profiles and clocking at or under 1ghz and see how things change.
Not sure why anyone would really need a higher clock than 1ghz but what do I know. I dont see any slowdowns at 1017mhz and I feel that anything faster than that would lead to heat or battery issues?
Yes, screen off profiles work. But they drain your battery faster than if you have no profiles.

thanks bro, i OC'd to 1017 and there are no issues

I'm not so sure about this. Have you tested this at all? Starting using screen off profiles of 365max/245min have really increased my battery life, especially when my phone sits idle for a decent amount of time. I don't think you could see more battery life by leaving the clock at 1ghz while the screen is off.

Every kernel that I know of out there drops down the clock cycle when the screen times out. The reason not having the screen off profile saves the battery is because SetCPU isn't constantly sending requests about the phones state and then checking that against your profiles to see if it meets the parameters set in them.
Now it could be a bit different for you. You might have a different set up or different apps that make having a screen off profile useful (ones that constantly update or run in some way). You just have to watch your phone for a few days and get an app that keeps track of that stuff so you know which route to take.

This is very true. It is definitely hard to make a blanket statement because no two people have the exact same setup. All I was saying is what I've been doin with the screen off animation and I've been having pretty solid battery numbers.
How to wake up the phone without battery removal? I have Virtuous 1.0.1 ROM with advanced kernel and from time to time I have wake up issue. I would like to avoid removing battery because I have otterbox case on my phone.
Do you know any other way to wake up yhe phone?
Well if you can't wake it up with the button on top it is a problem. Are you overclocked? Try lowering it.

wake up
I have seen the same behaviour with the stock htc latest (1.82.whatever).
top switch -- othing
opening kbd -- noting.
only a removal of the battery seems to help.
Of course it hasn't happened in a convenient place e.g. to see if I can still access it or if charging works etc.
If u installed trackpad wakeup, it seems to distort virtuous roms and keep the device from waking up all together.....there are posts about it in the developers forum

Also in some cases this is caused by underclocking with a screen off profile. I actually gave up on virtuous untill that problem gets solved. I havnt tried the latest version though.

There are 2 distinct "screen on" issues with slightly similar symptoms.
One is the "screen wake issue" what is common with Virtuous, and typically caused by certain combinations of overclocking, and screen off profiles.
The screen wake issue is very well discussed in the Virtuous thread, and commonly/easily solved with the proper screen off settings.
http://forum.xda-developers.com/showthread.php?t=967153
But the screen wake issue, as far as I have experienced, manifests with screen sometimes flickering on for a second, and sometimes responding to multiple presses of the power button, or by opening the keyboard. There is a different issue, some have called "SOD" (screen of death) where the phone seems completely dead until you pull the battery and reboot. This seems to be more what you are describing, but I'm not sure. The cause of the SOD has not conclusively been discovered, and there is currently no known surefire solution. But it may be hardware and GPS related, maybe kernel related. Personally, I've experienced this across several custom ROMs (Virtuous, CM7), kernels, as well as stock. The only luck I have had, is that the stock DZ ROM with the Godspeed kernel is the only combination which seems completely free of SODs. One person sent his phone into HTC due to SODs, and they said it was caused by a faulty GPRS module, and fixed it by replacing the mainboard. Another person send this phone in, and it was returned untouched, with the same problem still present.

Why people still do this just boggles my mind. All current kernels drop the processor down when the screen is off. There's no need - at all, for a screen off profile. It creates a wakeup issue as you can tell since SetCPU has to refresh the phones state then switch profiles in order to allow the processor to move into a higher state. That takes a lot of time (in computer time) thus creating this 'bug' that doesn't actually exist. The OC bug however does exist and is present no matter what you do aside from keeping it at 1.1GHz or less.

I had the screen wake issue on Virtuous, with NO screen off profile and OC'ed to 1 GHz. Making a screen off profile, but leaving a wide range for the CPU speed (not underclocking it) and interactive governor solved the issue in my case.
That might work better since most people I've seen tend to use the conservative or powersave gov. in their screen off profile. I'll correct myself too, what I said was from a CM standpoint since I've yet to use Virtuous.
Yeah, the screen wake issue on Virtuous is different from the one on CM7. If I remember properly, on Virtuous, using the advanced kernel results in screen wake issues for everyone or most people, unless you make some SetCPU/CPU Tuner setting adjustments.
Do you have SetCPU, or another program capable of CPU clock control installed? If not, install one of them and bring the max clock down... the Advanced Virtuous kernel boots at 245min/1516max - I noticed this after a fresh install of Virtuous 1.0.1/2 and the Advanced kernel

Completly agree.
I am shocked and appauled that most don't seem to understand that the os and it does not matter which(I.e. android,ios,windows) or platform (I.e. smartphone,tablet,desktop,etc) when you overclock more than just ur cpu speed is changed. If u have any experiance overclocking cpus on your home computer, you know u cannot let your system hibernate because it will not wake up. All operating systems allow the cpu to completly turn of in hibernation until it recieves an electrical pulse from the board. But if ur cpu goes from off to high it pulls way to much electricity and can't process then commands because all the recouces went to waking. If you have sleep parameters set with a narrower range the system will have enough resources left to process ur intial command...when it comes to sleep to wake there are no in between frequencies.

ROM: Virtuous 1.0.2
Kernel: Virtuous Advanced 2.2.0
I'm having trouble with my screen struggling to turn on when I wake my phone if the cpu speed is anything above stock. If I push the power button once the capacitative buttons light and nothing else happens, if I push it a second time the lights turn off again and I briefy see my lockscreen flicker before my pained eyes
If I do this cycle many times over eventually I'll get lucky, but there's no pattern to the success and it's very frustrating.
The symptoms are similar to this thread: [Q] Phone unlocking screen issues. The method described there to solve the problem was to turn off on/off animations. I don't think this solution applied as I'm not using CM7.
I think the touchscreen input is recieved despite the screen itself having no picture - for example I can unlock my phone by swiping down (stock Sense lockscreen). If I touch the touchscreen in the right place to open the dialer while I've "unlocked" it in this way, when the phone finally wakes after frantic power button pushing, the phone will be in the dialer app.
I think it might be related to Sense as I tried a stock Sense from rmk - [ROM]Vision_Gingerbread_S_HTC_WWE_2.30.405.1_Radio_12.5 0.60.24_26.08.04.16_M and overclocked using both Virtuous Advanced 2.2.0 and Pershoot's Kernel. In both cases I also had wake issues any time I tried to wake when the cpu was clocked above stock speeds (even 900MHz).
Further evidence towards a sense problem is that I don't have any issues when I'm at 1.4GHz when using CM7. I missed the sense apps too much to stay with CM7, however.
I have a workaround using CPU Tuner with a screen off profile of 246-806 Mhz, and I can then overclock freely afterwards. I can live with this but if anyone has an idea why this might be happening then I'd appreciate a solution.
As I've been lurking on XDA for a while but this be my first post, thanks to all you incredible developers who have made it possible for me to customise my phone in these fantastic ways.
Set your screen brightness to something greater than 50%. It's not a fix but a very reasonable workaround .

Wow that worked perfectly! Thanks!
Was that fix well-documented anywhere, out of curiosity? I'd searched these forums quite heavily and didn't see that anywhere. Makes me feel silly that it was such a simple fix - I'd been flashing ROMs all night to get the same bug
The screen off issue is thoroughly discussed in the Virtuous kernel thread. I forget the exact explanation, but its got something to do with the CPU stepping while the screen if off.
The common fix is a SetCPU/CPU Tuner screen off profile, as you seemed to have discovered. But adjusting the governor type in addition to minimum CPU clocking seems to be the common solution used. I think the interactive governor seems to work best to prevent screen wake issues.
http://forum.xda-developers.com/showthread.php?t=967153
Yeah, I read that thread fairly extensively but the solutions there didn't help. I can easily replicate the problem by setting my cpu with the performance governor to anything above stock speed (i.e. the cpu will be at one single speed the entire time, I think?). The over 50% brightness solution works very well (at the expense of more noticeable battery drain)!

I had seen the workaround mentioned on the CyanogenMod forums yesterday: http://forum.cyanogenmod.com/topic/20943-screen-doesnt-always-turn-on-from-sleep/
Sometimes when I lock my phone, the screen is unable to comeback up again when i try to unlock it. It just faintly appears when i press the power button but then dissapears back to a black screen. I am able to control (unlock etc, can feel the vibrations and stuff) but there is nothing on the screen. only after about 15-30 mins will the screen recover. Is there anyway to fix this?
This is generally related to governor of your CPU. At least I've fixed that problem by setting greater minimum MHz value in my tablet and experimenting governors.
Are you using any custom roms / kernels ?
could be due to undervolting as well
