This is a repost, since the earlier message never showed up.
I am running Cyanogenmod 7.1.0 DROID2WE, build VZW, on my Droid 2 Global. Starting a couple of weeks after I installed Cyanogenmod, I started having problems turning the screen back on. The phone works fine after a battery pull, up until the first time I either press the lock button, or the screen saver turns the phone screen off due to inactivity. From that point on, pressing the power button turns the screen on for a fraction of a second, then the screen goes dark again. Sometimes, the soft keys will remain backlit while the screen stays dark.
Sometimes, I can get the screen to resume working after many attempts, but, more often, I have to do a battery pull.
Does anyone know of a work-around? I considered trying a nightly build of Cyanogenmod 7, but the paid version of ROM Manager says that none are available.
Are you using the old, so-called “official” build that requires Android 2.2 (2.4.x stock) to be installed?
That one has a lot of bugs and is not supported at all.
I don't know whether or not the build I listed above is the so-called official build or not. It is the only build of Cyanogenmod that ROM Manager shows for my device. I haven't tried manual installation yet, only installation through ROM Manager. I also tried the "Liquid Smooth" ROM, but couldn't get it to boot beyond the Motorola logo.
See http://rootzwiki.com/topic/3069-dev-threaddroid-2-global-cm7-with-gingerbread-leak-kernel/ for the CM7 port for Gingerbread.
My screen would not wake up, I flashed Cyanogen Mod, the latest version, but as soon as my screen goes off and I tried to wake it, it'll just stay in a lighted black screen forever, nothing happens, it wont wake or respond to buttons so I have to pull battery. It didn't happen on just this rom, I tried other roms as well. And same results, is it my phone or rom? I just got the phone today.
Which rom are you running? And did you flash a custom kernel?
Try a complete wipe and reflashing, but don't restore any apps, if you do, and see if the problem persists.

I was running the latest version of Cyanogenmod. And no, I did not flash a custom kernel. I've already tried a complete wipe and flashed the rom like so many times. Like Cyanogenmod would install, but as soon as I put the phone to sleep and I hit the home button to try to wake it, it would be stay as a lighted black screen. The phone is responding to the button but it seems like the screen would not go on, the light for the 4 buttons lights up, but the screen doesn't display anything, just backlight. Please help, this is confusing me.
Set the phone to not sleep, it will just dim the light to near 0% brightness. I used to have this problem too on some nightlies and stable cm releases even and doing the above worked for me. I also bumped minimum cpu speed to 500-800 instead of 300, which lagged too much imho.

You say you press the home button when you turn the screen off and the buttons light up? Or did you mean when you pressed the power button?
When I press on the power button to wake it up, it just gives me a black screen. However the buttons light up when I touch them just the screen wont display anything.

That happened to me once. Did you wipe "system" in CWM before installing the rom?
Same Issue
Did you ever find a fix for this problem? My G2x just stopped coming on and I never changed any settings or anything. I've wiped davlik & user data; installed stock and custom roms, but every time the screen turns off the power button fails to wake the phone up. No lights flash or anything. I've found others who have the same problem but I haven't discovered any solutions. I'm guessing this must be a hardware problem since the power button does work to initially turn on the device and lock it but can't wake it. Any help would be greatly appreciated.
I'm currently running a rooted stock rom with the v21y BB that's been ICS-ified

I've found this issue to exist of literally EVERY build of CM that I've every used on ANY android device. I can't stand it. I finally stopped flashing CM all together because I hate not being able to wake up my device. NO OTHER ROM has done this before. Doesn't matter the model. Here's all the models that exibit this behavior that I've tested with.
Kindle Fire - CM9, CM10 and CM10.1
Galaxy 7 tab 2 - CM10, CM10.1 and CM10.2
Samsung Epic 4g (Galaxy S1) - CM7, CM9, CM10, CM10,1
Galaxy S3 Sprint- CM10, CM10.1
Galaxy S4 Sprint - CM10, CM10.1 and now CM10.2
That's very interesting. CM... I ended up sending the phone to LG to fix. I have a GS2 now so I gave the phone to my father. It runs great now.
sulotion to screen not waking up on cyanogenmod
I was having the same problem on my Samsung Galaxy note 2. I'm running cyanogenmod 11. I solved the issue by going into setting then display and lights and unchecking proximity wakeup. I hope this can help someone else.
Thank you a lot man! I was really in panic mode.
Not Waking up
This problem started once I have upgraded to official Lollipop. When I press the power button, the screen doesn't wake-up immediately. I had to press many times the power button to get the screen comes.
when I install cm10 beta2 by invendor than the problem started. apps minimizing automatically and always get back me in homescreen. I thought this is a bug of this rom but I was wrong.
then I install other roms that works perfectly before and I also restore the stock rom. but I still facing the problem.
tell me if it is a hardware problem
one thing I note that, if I hold the minimize button(but don't release ) than it work like before. after release the button it minimized apps automatically.
I lock the home screen by pressing power key. after thay my phone wake ups automatically.

So, say I install a new kernel, or update the rom, or just want a reboot or whatever.
Well my phone will reboot quickly, but then will seem to lag really badly when the phone is turned on.
For quite a long time (maybe 20-60 seconds, i havent counted) my power button doesn't do anything. My phone is responsive to touch, etc, but the power button won't put it to sleep.
Then about 20-60 seconds, again I haven't actually counted but it seems like a while, the phone will randomly load settings I have saved on boot from Trickster MOD and Franco's Display Control app. It is at that point that my power button is functioning again.
I'm not sure if it's these settings causing any problems, but it's weird and annoying cause I can't really do anything until the settings apply. It seems like maybe it's stalling on getting SU permissions, because once that toast message appears everything suddenly works.
Anyone ever have this issue? Running Paranoid latest, and Franco 38.
I'll keep messing with stuff to see if I can solve it myself, but just wondering if anyone else has had this issue.
I'm also experiencing a delayed response from trickstermod and franco's display app after reboot (I got used to it); but my power button is functioning well.

I actually have noticed the power button not working sometimes, usually with an xposed module that I reset. I always deleted the module and thought it was a bug. Ended up turning me away from xposed. Maybe I should look back into it again lol.

I think this delay is different for every rom/kernel. I noticed a serious delay on AICP (with a custom theme) to load widgets and to have all toast notifications at boot and this delay is significantly on SlimKat (power button is immediately functional after entering my PIN code). I've kept the same Xposed modules.
Hi - I have tried multiple Lollipop based ROMs on my OPO. All the Lollipop ROMs have exhibited the same failure on my OPO: When the phone wakes up, I will randomly see a totally black - and basically unusable - desktop, but have a fully working Status Bar and working pull-down Navigation Bar. Holding the power button also brings up the shut-down options. so, I know that my phone isn't dead or frozen, I just can't see anything on my desktop. If I press the power button momentarily to lock the phone, I will see the unlock 3x3 pattern grid when I power on, and I can unlock the phone - but, I see a black desktop.
I recently loaded the official CM12 nightlies, and I am seeing the exact same thing. One thing I have finally determined (which I suspected previously), is that there was some sort of App crash during the phone sleep that had a pop-up message on the screen when the phone woke up. After a lot of random finger mashing and loud screaming at the phone, I saw my desktop again, and saw that "Google App" had crashed. After clearing the error pop-up, my phone has worked fine without rebooting ... for now.
The problem with this is that the black desktops become more frequent as time progressed, eventually reaching the point where I would reboot my OPO and it would power up to a black desktop. In the past, I occasionally saw a flash that looked like a pop-up message before the black desktop, and now I have confirmed that is what is happening.
Does anybody know what is going on?
The problem can be the gapps package you're flashing. Try another one.

Thanks! Do you have a suggested gapps I should try? I loaded pa_gapps-modular-mini-5.0.1-BETA7-20150111a-signed with this build.
