How old do you want us to go?

Here is one from Slimkat on a tf700, and one from Zombi-X but can get you Chromi-X if you want it

Question and heat

Question: not ROM specific, but is there a notification pull down option that pulls everything down at once vs twice being required? I'll dig around.

ROM specific: It's really interesting to see the comments of heat being tied to network. That seems to make sense for me. It's in the top left, on the back, I think, in portrait mode.

I knocked it down 200Mhz in performance, set I/O scheduler to ROW, and things seem to be a bit better for heat and snappiness.

I bought one amazon game (with points) and it crashes on start, but I suspect that is an "art" issue, which amazon games haven't had to deal with yet. I'd echo that my take is that this ROM is definitely snappier than the kitkat builds. I'm willing to hang with this one, even with the battery and heat, and crashing! :)

Edit: Answering my own question here. I haven't tested yet, but "two finger swipe" will directly pull down quick settings. Not sure I'm too keen on that! will have to try it out.
[Asus Transformer TF700] toolmanz:
Beta 7, defaults, ROM2SD F2FS.

There is definitely something going on with recent apps. Used to be when I rebooted it would come back with no recent apps. Now they all survive after a reboot. This is something I have never seen before through

all the ROM's. Unless of course it is intentional in Lolipop :confused:

EDIT: Update .... my bad it is a new "feature" of Lolipop ...

This would necessitate a change to how the ROM and/or kernel should be constructed? OOM is this related? I used the square box at the bottom of the home screen and cleared out about 20 items, I think from several boots ago???

T
[Asus Transformer TF700] ikkeT:
Thanks, no point going further. We know those roms do not have the problem. Lets try the differences, the fs metadata caching is way stricter in zombi-pop, I'll try next with higher number in vfs... variable. Let's see if it would help. It still won't explain why ooms doesn't kill processes.
[Asus Transformer TF700] Rubister:
I'm no expert, but does that mean the kernel has a variable that tells it how many processes to kill based on triggers?

Seems like overkill. I don't know what the max bandwidth speed in Mbps is for the processor on the Tf700, but it is two years old isn't it? Seems a bit like hooking a V8 engine up to a Moped.
[Asus Transformer TF700] hks1234:
Hi, what kernel did u use with KatKiss?
[Asus Transformer TF700] ikkeT:
Finally ooms killer killed a process! The overcommit ratio was at 100. So the kernel is not buggy, it manages to kill a process with ooms killer. Not that it helped any, but proves it's user space config issue.
[Asus Transformer TF700] sbdags:
This is a good find - thanks. I think I will be testing this out later.

Also the diff between chrome installed to system vs data.
[Asus Transformer TF700] sbdags:
No I did some testing and the apps don't load even though they are shown cached in recents. They load for the first time if you select them after a reboot. ;)
[Asus Transformer TF700] _that:
No, the kernel has a variable that tells it how much more memory to allow processes to allocate than is really available. When too much of that allocated memory is actually used, the kernel needs to kill one or more processes.

Read this for more explanation: http://lwn.net/Articles/317814/
[Asus Transformer TF700] sbdags:
Beta 8 now being tested based on some of the experiments above.

So far so good ;)
[Asus Transformer TF700] corb06:
Ok!

I found that the Swipe left was working poorly, at first I thought it was broken but when you said it was working I did another try.

Its kinda jerky and seem to requires a long swipe for it to go away? Or maybe its just the cpu thats slow and animation thats jerky that the tablet dont really react fast enought compared to swipes?

When trying to quickly swipe 50 apps away I had to redo almost half of them to succeed.
[Asus Transformer TF700] Hawaiisa:
Clear all recents isn't implemented in the stock Lollipop from google either. I use omniswitch where there is a button to "clear all recents" and "all recents but last app". I find i to be working just fine :)
[Asus Transformer TF700] WesTechNerd:
Auto Rotate is bugged again with beta 7 and that11
[Asus Transformer TF700] fatboyinlycra:
Working fine with mine on that11 for me!
[Asus Transformer TF700] WesTechNerd:
Well **** I hope I didn't break something...
[Asus Transformer TF700] sbdags:
OK I have been testing an over commit ratio 50 tonight and so far I have not had a single reboot.

But chrome still introduces mega lag.

I think I'll be dropping it form the next release as it is either super bloated and our tab can't handle it properly or something makes it not compatible currently.

The AOSP Browser is a dream to use in comparison.
[Asus Transformer TF700] kansasboy001:
It is not out tablet. My old galaxy nexus with lolipop can handle chrome without lag. And our tablet can run circles around the galaxy nexus.
[Asus Transformer TF700] Lyvyoo:
Can I change dpi resolution on the fly? Or must to reflash the rom?
[Asus Transformer TF700] RunnyYolk:
Beta7 Data2sd f2fs _that kernal.

Actually Chrome has never run faster for me. I use it as my go to browser, which I never could before on this tablet. I regularly have 5 or so tabs open without too much lag. The whole rom is running well for me, but I wonder why Chome is good for me but not for others...
[Asus Transformer TF700] lj50036:
Maybe this is what you are looking for ..... :D

Thx Josh
[Asus Transformer TF700] cptsimian:
I also have no problems with chrome with no reboots at all. I am a bit OCD about clearing recent apps and I've turned off auto-sync, auto-updates, and update notifications even.

Thank you very much for the work you do.
[Asus Transformer TF700] Lyvyoo:
This bug is still present, but with one new error, after I restart the tablet (pressing few seconds the power button):
[Asus Transformer TF700] sbdags:
I haven't seen that for a long time.

Happens when dirty flashing?
[Asus Transformer TF700] Lyvyoo:
I use the dock most of the time and all wake up problems have started with the tablet docked. Before zombi-pop I installed only 3 ROMs - Crombi-kk (5 beta versions), Cromi-X (only 5.4) and this week Zombi-Pop. I do a full wipe before every instalation. Is the first time when I see this error. Most of the time, I use Skype with video on my tablet (two daily sessions / 2 hours) and Chrome, with no games, no monster memory apps.

I plan to buy a high speed micro SD for DATA2SD.
[Asus Transformer TF700] jeromeh:
I got that yesterday too when I ran the installer again to add the stock browser. So yes, happened to me when dirty flashing.
[Asus Transformer TF700] sbdags:
I can't remember the exact reason but I don't think it causes any harm.
[Asus Transformer TF700] nate39:
Well I disabled syncs and auto updates and so far I have had no lock ups or reboots but it is too early to know for sure if this helps but it seems to have made some difference.
[Asus Transformer TF700] pixbuf:
I've been running this ROM for a couple of days and am very impressed. One problem: I can't set the wallpaper; the background is all black. I tried the long-press method, and Settings->Display->Wallpaper, and neither works. I think I may have screwed something by trying to set an invalid wallpaper image file. Is there a way to blank out the wallpaper setting so I can try afresh (without having to do a system reset)? Something like

cat /dev/null > /etc/wallpaper ?

TIA
[Asus Transformer TF700] LDBAKE:
Wallpaper

I don't think it is anything you/we have done. I had the same problem with previous ROMS. I have better success by opening Gallery, select the picture you want to use, then select Set as wallpaper. Be sure to give it plenty of time to complete. Even this doesn't always work, but it works more often than not, at least for me.
[Asus Transformer TF700] Ozark_8125:
What TWRP version and install method are you using (ie, data/rom2sd/f2fs)? Did you format data when you switched to zombi-pop?
[Asus Transformer TF700] Lyvyoo:
2.8.4.0

normal instalation, to the tabled Sd memory

yes, I use the advanced wipe menu from twrp to format data.
[Asus Transformer TF700] pixbuf:
Great! That did it. Thanks a lot!
[Asus Transformer TF700] LDBAKE:
Wallpaper

I've also had success resizing photos to something like 1024 x 662. Go to Play Store and grab "Reduce Photo Size". Works pretty well for me.
[Asus Transformer TF700] davstar_apps:
Thanks!

I still need to try Beta 7, but Beta 6 of this rom is the only one out of a half dozen I've tried so far from 4.2-5.0 (along with a lot of tweaks) that actually makes this tablet faster (In my experience anyways)!

Ever since I got this thing it's been really sluggish and has narrowly escaped being smashed into a billion pieces on more than one occasion with how often it would freeze or take forever to load apps up. I think I might drop the resolution down to 1280x800 just to see if that helps it even more. The high res screen is nice, but since I don't like looking at freeze frame "action shots" every time I do anything it may be worth it to try. Not that it's near as much of a problem on this rom as it was before with CM12 or other KitKat based ones. :good:

Excellent work on this one! Tablet feels brand new for the first time ever...:victory:

Let's give it a try!

Let's see if I'm going to throw my Asus out of the window and buy a Samsung or keep it for good.

I'm really frustrated, thinking how much I paid for this tablet and how laggish it is ...
[Asus Transformer TF700] tiernan22:
I've decided to finally get a Nexus 9 and retire my Asus. I want to thank everyone around for the support over the last two years; especially Darren and Josh for breathing new life into this device. It's simply amazing what this community accomplishes.

You 'll be back ;) Nexus 9 is no fun :)
[Asus Transformer TF700] sbdags:
Well you didn't say what the problem was? But I can see:

[ 130.407148] Kernel panic - not syncing: Out of memory and no killable processes...

Hopefully this will be fixed in beta 8 which I am testing now and not had a reboot so far :)

Now do you want the fix on the same base as beta 5, 6, 7 or are you all patient enough to wait for a new base build over the weekend? :)
[Asus Transformer TF700] erisi:
HI Darren,

The perfomance I am getting with _that's kernel has become terrible. I can watch the letters I am typing appear on the screen after I stop typing (using Dolphin browser). Should I just wait for Beta 8?

Thanks!

Gene

fyi - If you set the user agent to "FireOS" you can watch Amazon Prime movies on the tablet :)
[Asus Transformer TF700] sbdags:
Yes some of us have it, and some don't.

It is very weird.

But a new build will be done soon :)
[Asus Transformer TF700] toolmanz:
I am very happy with how it is performing currently - I would be willing to wait for a new base build. Data2sd, _that, F2FS data, default tweaks, Fsync on.

But that's just me ..... :o

Or Something.....

Running Dirty B7 over B5, Rom2Sd _that, defaults (where did all the earlier settings go?)

PWR flaky

Lock Screen flashes 1/2 on PWR, then black, then Lockscreen.

Terrible Lag on Touch. (Had to turn on Show Touch to tell if touch takes)

Chrome is junk. (How do I kill a system loaded app so I can load from PlayStore?

Wifi is working poorly, slow access. (Maybe Chrome, but looks bad on Dolphin too.)

No OOM, reboots, though, believe it or not.

Hoping for your magic on B8. Thanks for the efforts. We really appreciate you Devs.

[Asus Transformer TF700] nephtys59:
Sounds promising

Installed this beta and I have to say it sounds very promising.

Still some lagginess but less than previous JB custom ROM I was using.

Experienced a couple of unexpected reboots but I find it normal, being this a beta version.

What bugs me is very slow boot time and anomalous battery drain.

I hope this will be fixed in next releases.

Keep up the very good work and thanks for your efforts!
[Asus Transformer TF700] nate39:
Let me add again that after I got rid of Chrome and Dolphin and turned off auto sync, it has run much better. I have had a couple of reboots in two days which is much better and it was while in a game that goes online, and overall it has been very fast. I guess all that has something to do with these problems. Thanks for the effort.
[Asus Transformer TF700] pastorbob62:
So we have been running Beta 6 since its release without any major issues. But the battery life was horrible. So for that and other reasons I bought my wife a brand new dock/keyboard (TF700-Dock). However after charging it to 100% and installing the tablet it did not work at all. No pointer, hitting any key would take me to the wallpaper/widget selection screen. So I thought I would try flashing and use Beta 7 while I was at it. Still no luck. Sometimes the keys type but more often they don't. And I still have no pointer and touchpad response.

My problem is I don't know if it is the ROM or the keyboard. Didn't see anything mentioned in the OP about it. Are there issues with the keyboard/dock and this ROM? I did dirty flash Beta 7 with just a cache/dalvik wipe. I am using _that's kernel.

Thank you in advance.
[Asus Transformer TF700] Hawaiisa:
The dock is working perfectly for me on beta 7., so I don't think this is a general issue.
[Asus Transformer TF700] pastorbob62:
UPDATE!

Yeah, that's kinda what I thought. I just removed it from the dock and gave it back to my wife until I can do some further troubleshooting. But it looks as though I received a defective dock. Dang! Just our luck.

Update - Damn! It's even worse. I tried my TF300 in this dock and it works perfectly. So apparently I have a bad tablet not a bad dock. Although I didn't think the TF700 dock would work on a TF300T apparently I was wrong.
[Asus Transformer TF700] sbdags:
Another 'pop' at Beta 8 today.

Tried a few new things and refreshed gapps. Looks like chrome will be removed with a 'use at your own risk' for now.

I can pretty much replicate an out of memory reboot using it for a few minutes.
[Asus Transformer TF700] jp071848:
Thanks for highlighting your issue with the dock, as it made me play around and discover a problem with mine. Running Beta 7, the tablet works fine on its own, and if I plug it into the dock while active, the dock works fine. If I put the tablet into the dock shut down, and start it docked, it crashes about 3/4s of the way through the boot animation. Sometimes it gets just past the boot animation then crashes. Quite a repeatable crash. Remove it from the dock and it runs fine, though I may have to let it re-boot a few times to stabilize.

Great ROM, best one I've ever run. Seeing Antutu scores of 22K+ running internal, I don't think I'll even bother with Data/Rom2SD

Thanks for all the hard work
[Asus Transformer TF700] Jcei:
I feel the stability issue could be related to the luminosity. I experience pretty much no issues if i avoid the lowest level.

Reboots

Hi, i have installed both kernels on b5 ans b6. And i've noticed That i've reboots when i try to connect to an account like facebook with a secure access. I launch Facebook, enter the login and the password, then Facebook crash and the system reboots and reboots and reboots... So i flash the rom with another kernel but in reboots again. I try the Last kernel with same issue. I try with no wipe and with wipe cache and dalvik. But not a chance. when i see on my smartphone a security message from Facebook witch saying à New launcher. ..blablabla. i agree with this message on my smartphone and i start m'y tf700 with no reboots now. I've also noticed this issue with anothers secured accounts. I'm on b6 with data2sd with both kernels.

Many thanks for this rom and your great work on it.
[Asus Transformer TF700] sbdags:
Well Beta 8 was tossed out.

I rebuilt on a new base for Beta 9 - same issues. :(

lj50036 is now investigating some oom patches that look like they may help us.

What is clear is oom killer is not doing its job properly.

So no update until this is fixed.

[Asus Transformer TF700] wenchien:
enable swap to avoid OOM conditions

For people who would like to trade some smoothness to avoid OOM, here's how:

create a swap file

IIRC f2fs doesn't support swap file yet, thus you must have an ext4 partition at least, or you may use a swap partition instead if you'd like f2fs on both of /data and /datai.

Let's assume /data is an ext4:

root@tf700t:/ # dd if=/dev/zero of=/data/swap bs=1048576 count=512

This will create a file /data/swap and its size is 1MB(1048576)*512 = 512MB.

remove vm related modifications in /etc/init.d/96CleanTWEAKS

At least the vm.swappiness should be kept as 60 instead of 0. By adding a '#' at the begin of the line

/system/xbin/sysctl -w vm.swappiness=0

would make it a comment instead of a command. I also removed the modifications of vm.dirty_ratio, vm.dirty_background_ratio, vm.dirty_expire_centisecs, vm.dirty_writeback_centisecs, vm.min_free_kbytes, and vm.vfs_cache_pressure.

create an init script to enable swap

Add a new file as '/data/local/userinit.d/05swapon':

#!/system/bin/sh
SWAP=/data/swap
if [ -f $SWAP ] ; then
mkswap $SWAP
swapon $SWAP
/system/xbin/sysctl -w vm.dirty_expire_centisecs=3000
/system/xbin/sysctl -w vm.dirty_writeback_centisecs=500
fi

You may modify the vm parameters here to fit your needs. After the file is created, do

root@tf700t:/ # chmod 755 /data/local/userinit.d/05swapon

to make it executable.

After reboot, you may tell the swap is working by:

root@tf700t:/ # free
total used free shared buffers
Mem: 990548 954664 35884 0 620
-/+ buffers: 954044 36504
Swap: 524284 34444 489840
root@tf700t:/ # cat /proc/swaps
Filename	Type	Size	Used	Priority
/data/swap file	524284	34444	-1

Guess a 256MB or 192MB swap would be sufficient for most cases. If you'd like to change the size of swap, just do

root@tf700t:/ # swapoff /data/swap
root@tf700t:/ # rm /data/swap

And repeat step 1 to create a new swap file.
[Asus Transformer TF700] FordPrefect:
How could creating a swap file help with the OOM issues we are having? It's my understanding that swap works as a buffer that increases the amount of (virtually) available memory. So, it would make OOM conditions raise at a bigger extent of memory usage, but it would not be able to "cure" them, right?

What are your observations with using this?
[Asus Transformer TF700] wenchien:
Humm... Sorry I don't get that why "it would make OOM conditions raise at a bigger extent of memory usage"...

Didn't find OOM conditions on my TF700, at least not that I'm aware of, though it does introduce lags due to the poor IO performance TF700 has.
[Asus Transformer TF700] FordPrefect:
Let's say the physical memory is 4 GB (as an example), and the swap space extends this to 5 GB. The OOM condition would then start after allocating 5 GB, instead of 4 GB ... but it definitely will still start .... unless I'm on a completely wrong track with my knowledge of swapping.

If the swap mechanism really helps, some clever guys could come up with an adjusted fstab that points to the external sdcard, isn't it? Maybe that's the approach for a work around untill someone can figure out a solution for the core problem, which is OOM condition.
[Asus Transformer TF700] hardslog:
We found some oom patches in the source code for the kernels that were implemented in the Grimlock kernel about two weeks ago that seemed to help with the out of memory kernel panics. We are going to implement these in _that's kernel and see if that will make a difference.
[Asus Transformer TF700] NapalmDawn:
Hi folks. I'd like to tell you guys about my experience flashing this and how the rom has been so far.

In short-actually quite good. I had some issues updating my TWRP to the newest. Via the PC, it would sit there telling me it was sending the twrp blob but then never actually say finished. The TWRP manager app would fail to load it while terminal commands said that it WAS loaded but I kept coming back to _that twrp 6.something. Finally, one time it did take and I'm now on twrp 8.4

Once that was settled, I did my big wipes and flashed the rom. The rom "cooked" for a scary long time to the point that I was like "crap...it's boot looping. Damn I guess I'll have to res....oh...there it goes." Once it booted and I configured some things, I restored a few items from TiBu. All seems good.

I have 2 questions-do we have working ASUS apps for lollipop? I know we had just gotten there for KK but I'm not sure on *pop. Also, is there anyway to fix so much white on white on white? Example-in the notification bar, advanced task manager pro is using white text and the background is white. I did fix white text on white folder backgrounds (apex setting). So far, I'm liking the rom a lot and don't have any issues with it. Today is my day to test it off power. It's hard to check the drain exactly since I have a dock. So far, the touchpad and keys seem to work just fine.
