Since we have Q&A stickies in the Inspire and Captivate forums (as well as a few other fora around here), I thought we need a general CM7 Q&A here for the Atrix.

BEFORE ASKING QUESTIONS IN THE FORUMS, ASK YOURSELF:

Has this question probably come up so often that there is an FAQ that includes it?

OFFICIAL CM7 FAQ FROM THE ATRIX-DEV TEAM




I know how much people LOVE to post questions in here as if it's the CM7 ROM and get all pissy about how things dont' work, but keep in mind that if that were true and a bunch of stuff didn't work it would NOT have been made part of the nightly CM7 releases. Also, it wouldn't have been released if that were the case. The devs work very hard to make sure most major problems are taken care of before every release, but if yer flashing A NIGHTLY, keep in mind it comes with NO promises of functionality and it is STATED in the OP that it shouldn't be used as a daily driver. So if you have a stable version, such as the lastest stable version found on the development page OP, then post a question or comment here after searching for the answer with search feature here and google. Otherwise, there's a Nightly post section as well in the Development side if you wanna look there and that's what yer using. Most of the time if there is a major issue and you can't find it on the bug tracker than it's yer phone, or something you have installed that is messing with the functionality of the ROM. Lastly remember folks, it's the developers job to make their product work with the ROM, not the other way around. Have fun, happy flashing!

You know what ? Its a damned good idea. Too many people are cluttering the development thread. Now since no one else has posted a question related to CM7, I have one:

Can someone help me figure out what is eating my battery on standby ?? I don't have that power hungry facebook app and I did some tweaks found ( via SetCPU ) that I found in the development thread, but it made very little difference. The thing is, I just have no idea how to monitor what is using all the power. How did they figure out that facebook was causing a big drain ?

Do you use google latitude?
A very good thing is use BetterBatteryStats to really understand where the CPU is being keept awake. The embed battery stats for example only showed me Android OS as a culprit, but gave me no further details..

my 2 cents

Had anyone else had trouble getting the hbogo app to work on CM7? I can login and try to play a video but get audio with no video. The hbogo splash screen plays perfectly when playing a video for the first time.

Edit: Just found a bug report for this exact issue. (issue 163, sorry, I can't post links.)

When I receive a call, my phone goes to a lock screen, I have to swipe the lock screen to answer. On stock, when I got a call, the screen woke up in the dialer app and all I had to do was press the answer button. For the life of me I can't seem to find a setting to change this, any input appreciated.

Do you by chance have Tango installed? I had it for all of 2 days and noticed my battery died about twice as fast as it normally would. I usually get a good 16+ hours easy with moderate use but was only getting about 9 with the same usage. Did a quick google search and verified tango was the culprit. Uninstalled and back to normal. I don't know if this applies to any other video call apps but might be worth looking into.

Think I already read something about it, but cannot find right now... What's the deal with /mnt/emmc and /sdcard in cm7 ? Is it possible to get it back like the stock rom ?

I am having problems using Titanium and taking screenshots, think it is something related...

Thanks in advance!

Wifi connectivity drives me nuts on cm7. Had to turn it off and on in order to connect. Someone mentioned to edit propbuild. Idk what that means.

You need to go into Setting/CyanogenMod settings/Application, check "Use internal storage" then reboot your phone and it should be back to how it was before.

Betterbatterystats seems to have found some interesting things. Phone on for 1hr and ten minutes.

Under partial wakelocks:

Lightflow: 1hr10m3s
AlarmManager: 58m13s
JuiceDefender:55m44s

There is more ( I can provide screenshot if required ), but those are the top three.

I do find this a little odd. Juice defender was just installed the other day and I can't see how it would cause any problems. Battery was a bit crappy before and didn't get any better/worse. I froze lightflow the other day and battery drain was about the same.

filthyfnj24: Nope no Tango.

I can provide a list of apps if would help as well.

I got watchdog and Im able to detect what cause battery drain while on standby. Its the "suspend" service running on the background with 90% cpu usage ... as soon as I heard the warning from watchdog, I wake my phone and that "suspend" stop immidately. Happen to me since I got this rom cm7. It didn't happen before on alien...

I as well am having problems with Suspend and abnormally high sensor usage.

EDIT: upon further investigation I have narrowed down AlarmManager as causing a lot of partial wake locks, but I dont have any alarms set and have not synced my calendar and have the Calendar alerts turned off. However Suspend is showing as a problem as well.
I'm using BetterBatteryStats, SpareParts, and the stock battery manager to try and track this down.

Well, after eliminating Lightflow and turning off Beautiful Widgets small weather, things are improving. Instead of losing 5% per hour on standby, it is now down to about 3%. Juice defender and Alarm manager are still at the top of the list, In 2hrs and 18min I have:

Alarm manager 33m12s
Juice defender 27m56s

So, Juice Defender is next on the list. The funny part is I know that CM7 is causing this. Battery used to last near forever on standby.

Ever since I upgraded from pre-beta 4 to Beta, my phone has had two horizontal deadzone lines on the touchscreen. This persists from ROM to ROM, and is getting to be annoying. I have no warranty, as I bought the phone from a guy who won it in a contest, unlocked it and brought it to another carrier.

Is there any chance that this is a software issue, and can be repaired?

I got it !!!!

Alarm Manager is no longer a problem. Phone now sleeping correctly. I disabled background date, topped off the battery and verified via Betterbatterystats. Now if we could disable background data while it sleeps and re-enable it when you wake it up then we'd be set.
