Having a problem with the lock screen in CM10.1 that is happening more frequently.
It seems it happens after I open the case lid and the Nook HD+ wakes up. I use pattern lock (but it's happened in the swipe lock also), and for a moment, it looks like it's unlocked. The desktop or app that was up when it went to sleep is there, but only for about 1 second. It goes right back to the lock screen. It repeats over and over. At first, I thought only a reboot would fix it and allow me to unlock it, but I found if I hit the power button to put it to sleep and wake it up, it typically unlocks. Sometimes it might need me trying that a couple of times, but it usually works.
Ideas? Anyone else having a problem unlocking after sleep? So far, I'm not sure if it's just lid-induced sleep or if it would happen after I use the power button to sleep it.
Again, it doesn't happen all the time, but i'm finding it happen more frequently.
Thanks!

I have heard about this problem from several people, but usually it is on an HD+ with the cover that wakes up the tablet. However, I just experienced this a few minutes ago and my Nook has never had a case on it, let alone one that wakes it.
It happened when waking it with the n button but after turning off the screen with the power button and back on with the power button, it worked. (not turning off the Nook, just screen off and back on)
So it appears that it is not only the magnetic wake up that causes the issue.

Mine does that too. I thought it was a hardware defect, but I tried another one and it does exactly the same thing.
So far it's only happened with a case-induced wake for me. It happens regardless of whether I sleep it using the case or the power switch.
The lockscreen loop stops if I sleep/wake it using the cover consistently, but it doesn't go away if I sleep/wake it using the power switch, oddly.
same problem with no known solution

I have the same problem and no solution. I wonder if a newer release of CM would help.
Also, in regards to temporary coping, when this problem appears is there a method (besides reset) to deal with the problem. I noticed that sometimes I can eventually get past the lockscreen without restarting, but I'm not sure what causes that. The best solution I have for my wife at this point is I delayed locking-after-sleep to 30 minutes.
Two-user set-up (my wife and me). I am fairly new to the scene--first time I ever loaded CM on any device. I recently bought the HD+ from Best Buy for $150. I tried to follow the verbatim instructions from e.mote titled "[NOOK HD/HD+] Installing CyanogenMod 10.1 for Dummies." I haven't used custom ROMs much since my heady days with my Palm Pre.
I'm in the same boat. Hd+ running CM 10.1.3. I wonder if this still happens on the 10.2 builds...
While on 10.1 this happened to me every time after charging (well, maybe not every time, but that's when it happened...), but if I just turned off screen and then back on I was fine until next charging.
I put on 10.2 earlier today (from Iamafanof site, so not from here). Will be interesting to see if the problem is till there, but I won't know tat for a while yet.

Im seeing this on both 10.1 and 10.2 on my nook HD no cover.
I'm seeing this even without a lock screen. The screen turns on for a second, after that turns off. After many tries it works or after a restart. With lock screen it is the same as above.
Happend on CM 10.1 and CM 10.2 with a cover
So there's no solution to this problem and you just have to reboot it?
You just close and open the cover again

I'll try that again but I don't think it worked.
I have been having the same issue as well with mine. Just curious if really has been a solution to this?
No it is a hardware issue. There are two options close and reopen cover or cut magnets out and turn on manually. I don't think anyone has tried more powerful magnets if you want to test that it would be helpful.

I kinow its an old thread, but I Fixed it by closing and opening the magnetic cover, rather than using the power/off/on screen button and it worked.
Only fix is to do one of three things. Remove the magnet from the cover, remove the cover is self, disable the lock screen. It's because the cover and lock screen confuse each other and it has the cover wake it, then the lock screen sleep it, then it sticks. It's very well known, and nothing to panic over, just really freaking annoying.
I just recently got an HD + and put CM 10.1 on it. Every once in a while I get this weird glitch when waking it up from sleep. I get the home screen with the unlock button in the center per normal, but when I try to swipe to the right for the desktop icon, the screen flashes once then goes back to sleep. No matter how many times I try to wake it up this way it just goes back to sleep. I fixed it the first few times by rebooting but this morning when it did it, I tried swiping to the left to the browser icon and it worked. It brought up the browser and I just quit out of it to get to the desktop.
Anyone else have this happen?

Lots of folks see this. It is usually caused by your case with a magnet in it to turn the screen off. Just open it twice.

Thanks Leap. Didn't even think of the case being the culprit. Thanks for the info. I didn't even know the case had the feature until I got it.
I was thinking the Nook had a photocell that was reacting to opening and closing the case but it's a magnet that does it?

I have had the screen do odd things from time to time but I have never seen "some weird pixellating thing".
did you do anything to fix it?

Did you try cleaning your fingerprints off?
Sent from my SCH-i705 using XDA Premium HD app
yes i cleaned the screen off and all my finger prints. I was doing some reading and some people say that they had the same problem and they said something about holding the power button for 20 seconds and then holing it for 2 seconds to turn it on. I tried that but it still eventually did the same thing. I also read some people said that once they put a screen protector on it seemed to help. What do you think?? Have you had this problem at all. I cant return it to B & N since its rooted and was purchased off craigslst. Is this a known issue?
When mine gets weird and I get phantom finger presses just shutting the screen off and turning it back on fixes it. Usually happens after long game sessions.

This is the only problem I have with my nook HD+, but I am getting close to finding the problem.
I have managed to get dmesg to print out when the problem is occurring, and that isn't easy when it wants to start doing random presses !
Every time this problem occurs I see the same thing:
lowmemorykiller: killing 'ndroid.settings' adj 1000 to free 19712KB on behalf of 'kswapd0' because cache 85116KB is below limit 86016KB for oom_score_adj 12
free memory is 5568KB above reserved
When the crazy screen presses start happening lowmemorykiller begins closing all sorts of things one immediately after another, and then crashes out with a negative memory available like :
-58329KB available
I'm guessing there is a memory leak somewhere.
I've been getting phantom touches since upgrading to CM 11 (6/16 build and up), although I left the Touch & Hold delay to its stock "short" setting when I upgraded, so not a good experiment. (Two variables.)
For me, a web page will register a "click" while browsing with my thumb hovering about an inch over the screen.
I have "show touches" enabled, but I don't see a touch.
I have a screen protector. (Have had it for months.)
For now, I'm setting the Touch & Hold delay to Medium as a work around.
I have the same problem as others that sometimes after sleeping with the magnetic cover, even with the correct password I could not log in. I have delayed the screen automatic lock to 30 min and usually have to fix it with a restart if it happens.
I have another problem that if I have the nook covered with the magnetic cover for a time period longer than 2 hours. It seems to have been turned off. I have to try holding the power button to turn it back on and it will go through the nook splash screen and then the cyanogenmod start animations. Is this something expected with cyanogenmod? Has anyone else experienced this?
If it's a bug, I am wondering whether updating to CM 10.2.1 will fix it. I have read the first problem cannot be fixed and it might be hardware related. Is the second problem hardware related too? Thanks,

You need to open and close the cover twice. It is a known bug on all CM versions.

Hum, I can't seem to reproduce my second problem for the last two days. The symptom was that when I tried to press the nook button or the power button to wake it up, nothing happens, it stayed at the black screen. I guess basically what I did was holding the power button to shut it off and then turn back on. I guess it might have needed a second time of opening the cover. I will keep watching and see whether this is the case.
Hey guys, this is a weird error that just started for no reason that I can think of. I had the latest nightly build on my Nook HD when all of a sudden various parts of the screen would just be auto tapping. I tried restarting multiple times, I even went for a factory reset but ended up simply flashing TWRP on it and flashing the latest AOSP Rom.
The problem is, when I load over to TWRP, I'm still getting these touch errors. Does that mean that it's something hardware wise that was broken? Does anyone have any advice on what to do next?
All and any help is appreciated, thank you.
Try cleaning the screen thoroughly. It gets very sensitive when dirty.

Sometimes putting the nook to sleep and waking it up again with the power button is enough to fix "stuck touches", something gets reset when the screen is switched off.
Also, some 3rd party chargers can cause continuous random "ghost" taps all over the screen while the charger is plugged in, but the problem goes away as soon as the charger is unplugged.
One thing that can help you figure out what's going on is going into developer options and enabling the "show touches" option. That way you can at least see when a "ghost" or "stuck" touch happens. Be careful when entering passwords in this mode though, since it makes it easier for someone else to follow what you're tapping too.
