[Milestone XT720 Android Development] Zachary57:
When you speak about voltage do you mean CPU voltage or phone modem one?
[Milestone XT720 Android Development] peshovec:
when i speak voltage, i mean cpu (probably not only the cpu, but let keep it simple)...

http://git.omapzoom.org/?p=kernel/omap.git;a=commitdiff;h=337cafa871baae4699dbd9f2cedb7466e5df1f12

http://git.omapzoom.org/?p=kernel/omap.git;a=commitdiff;h=4243e3ab5eb2ff8cccb022387e49a2bcd9c6175e

1st method (aka out of the box and stock)

using fixed table: freq and voltage

2nd method (smartreflex)

the voltage per freqs start from some value, then are tunned to match the concrete chip (every chip differs)

3rd method (mentioned in the above patches), which is claimed to be recommended by the h/w people ...

Of course it is not that simple, the way the transition and scaling matters, as well the average load, temperature etc....

I suppose that you wonder what is the connection between voltage scaling and loosing radio ?

Actually it is not so direct connection:) when applying the above patches, the kernel configuration is changed above some threshold. The netmux related modules, are sensitive to it, so the radio was non working... After i figure that, was able to have radio working with the above voltage scaling patches ...

If the phone had external power (e.g. usb cable to the pc), it was fine, cpu was scaling up and down etc.... logs show that phone enter (and exit) from some sleeping state (although /system/bin/uptime did not show any time spending in sleep, but i suspect that sleeping time is counted only on battery discharge cycle)

When the phone is disconnected from exernal power, as far as i play with it it is good (probably the cpu scale again up and down ), even if press quickly twice the power button, the display is going black, then back on....

BUT if i let the phone to sleep, then it never wakes, just hard/cold reboot after few seconds ... (and no logs are generated, the same behavior as battery pull)
[Milestone XT720 Android Development] Mioze7Ae:
FYI the XT701 folks (stlifey, fentensoft, xmoon) have been working on their kernel quite a bit. For example stlifey told me on irc that they were able to get 1% battery working on 2.6.29 using this: https://github.com/XT701/Kernel_DEPRECATED/commit/94fcec455bd654147f2b4d5e834e02e27373b28c

Lately I think they're working on porting 2.6.32 to their device (I can't quite tell what the status is). See the various kernel repositories https://github.com/XT701/Kernel , https://github.com/XT701/Kernel_DEPRECIATED , https://github.com/XMoon/KERNEL , and also in other XT701 organization member repositories etc. Lately they seem to be trying the Defy+ kernel sources.
[Milestone XT720 Android Development] eejin2:
lol, no i dont use any external memory for apps. i try to keep the number of apps i have as low as possible, and i rarely used swap in the past, but whenever i do, it works okay.

how to i "disable /system/etc/init.d/02ramz" and "grab a dmesg?"?
[Milestone XT720 Android Development] kousik:
I generally use adb for this:

C:\> adb remount
C:\> adb shell
# rm /system/etc/init.d/02ramz
# dmesg
[Milestone XT720 Android Development] Zachary57:
Maybe it will be good to implement a long sleep mod to our phone to be able to stop phone ( even if it's not really ) and to keep fastboot kernel.

I mean an option that unload all system and keep only kernel in memory and that re-load all system when long press at start button ( I don't know if it is possible ).
[Milestone XT720 Android Development] 3rdstring:
There are numerous "hot" reboot apps in the market that reload the android GUI without touching the kernel.
[Milestone XT720 Android Development] peshovec:
killing system-server do the same....

but as i understand, the goal is something similar to "standby"

e.g. something like echo mem > /sys/power/state

i have not strong memories, that i tried that one, but was not able to wake the phone after ....

at least for now having a charger around is not so bad workaround :) :D
[Milestone XT720 Android Development] Zachary57:
Yes something like that. The goal is to have phone like halt but without losing fastboot kernel. In case of no charger or when phone have to be stop.
[Milestone XT720 Android Development] syrokos:
Have you read about KSM? sounds like a good solution for our RAM problems but I don't know it its possible to use it, since it appears to be 2.6.32+
[Milestone XT720 Android Development] peshovec:
i run some tests, (look at the screenshot -> uptime)

so far my current config seems stable:)

differences from the default:

kernel:

https://github.com/CyanogenModXT720/android_kernel/commits/xt720-test-patches

highlights of them:

swap enabled, 800Mhz by default (imho no need to overclock anymore)

in the attached fastboot.zip you will find the boot-custom.img :

highlights of using it:

the above kernel

no 2nd init (as with fastbooting imho it is needless)

p.s. btw, using auto process purging once a day, seems very good to avoiding memory pressure
[Milestone XT720 Android Development] Mioze7Ae:
Sweet!

One concern... avoiding 2nd-init means that there are now two boot mechanisms to debug. If you bake the rootfs into boot.img, then you have to keep track of boot.img+ROM compatibility.

On the other hand, is there really any downside to 2nd-init and keeping a unified boot process for normal and fastbooted kernels? If there are actually any real disadvantages to 2nd-init, I think there has to be a more elegant and generic way to bypass 2nd-init rather than baking the rootfs updates into boot.img... we should be able to pare down the boot.img init scripts so that the /system/etc/rootfs updates are merged without using 2nd-init to restart /init. I pondered this a bit a while ago but I decided it's less error-prone just stick to 2nd-init.

[HTC Incredible S] mac4rfree:
Hi Guys,

I am planning to buy either Incredible S or Sensation. Their Price difference is 2K.

I have read somewhere that Incredible S will be stop from service soon.. Is that so??? If so, i hope the ROM development activities will be carried forward here.. :)

So , Which one should i buy??

Cheers!!!!
[HTC Incredible S] vizzy:
Personally I'd get a sensation. I only got this due to it being on sale and I needed a phone quick. .....2k? What currency ?
[HTC Incredible S] mac4rfree:
Indian Rupees,, Incredible S 20K INR and Sensation 22K INR
[HTC Incredible S] vizzy:
Check the specs but I'm pretty sure sensations are more powerful for pretty much the same price.
[HTC Incredible S] pec0ra:
HTC Sensation is a little bit more powerfull ( at least the processor ). The mobile itself isn't that much better than Incredible S but it has a better support. It is more recent so it gets official updates first and will probably still get more updates than Incredible S. HTC Sensation also has been a very popular phone so I guess it also has a better comunity than the Inc S. The only thing that would be making me bying an Inc S (besides the price but the difference seem low) would be the design. I like a lot the design of the Inc S and it is a little smaller.

You'll need root access

get a root uninstaller and remove screenCapture

[Android Software Development] Lokifish Marz:
I have this feeling you are about to be in high demand if all the ISC Webtop 3.0 videos are accurate. It's looks like Moto killed Ubuntu and replaced it with tablet mirroring mode.

BTW- Played with this on an Epic 4G and really like it. Could have used this last year for the Evo Desktop PC.
[Android Software Development] devwithzachary:
really? well thats interesting, bring them on, everyones welcome here :P
[Android Software Development] mrWax:
Runnin slow linux on android ? -> lets do Ultralight

Howdy, pardners!

I suggest ARM porting Puppy linux or some other other really light distro to gain maximum performace out of mobile device.

Also there ultra-light desktops . It seems that the best would be Ratpoison or Awesome. These are easy to incorporate into now available port of Ubuntu for android.

These should together provide fast and small display suitable linux env. for your mobile device!

see ya round!
[Android Software Development] devwithzachary:
Yes I think your right, I will look at making my next support distro one of these amazingly light distros, get the most power we can our of our devices :D
[Android Software Development] dustinhayes93:
In your opinion, which of these distros is the fastest? I have a single core device so need all the help I can get lol
[Android Software Development] devwithzachary:
either ubuntu 12.04 with lxde or debian i would stay away from gnome it takes alot more memory . At the moment i love debian its my 'daily drive'
[Android Software Development] dustinhayes93:
Debian it is! Btw thanks for your work. Its amazing seeing full desktops in your pocket... Amazing work!
[Android Software Development] Andrioid.:
I got Debian to work on a Huawei U8800 Ideos X5 with the Aurora 2.0.4 ROM.

Everything was running smooth and great, but then I logged out from the system to see if I could switch DEs. :D

From there, all I saw was the wallpaper of the desktop and nothing else.

I exited with the terminal and tried again. Now I get this message:

Is there any way I could reset the cache and try everything again?

ALSO, after the sh-ing debian.sh, this is what I get:

It was different than before, so I thought this would be useful information.

I have no idea what to do at this point. :confused:
[Android Software Development] devwithzachary:
Hmmm looks like you broke vnc :P I would recommend reinstalling vnc do apt-get remove tightvncserver then apt-get install tightvncserver

then do a restart of your device and try again.

If you want to use a different desktop you need to configure it in in /root/.vnc/xstartup vnc dosnt run right if you log out of a session and thus is broke, didnt think vnc even let you log out but guess it will :P
[Android Software Development] Andrioid.:
Reinstalled vnc, rebooted phone, still not working.
[Android Software Development] con_ritmo:
the speed and responsiveness of debian on a nook tablet / cm7 is great!

however, is there any way to get flash installed/working on debian's iceweasel?
[Android Software Development] Bilgets:
what i was wondering is only, hows the battery?

as far as my lofic go, ubuntu on laptop is a battery drain.. and how if its running on a phone that majority has lower capacity of battery
[Android Software Development] devwithzachary:
Hmm ok you might have to try using a new image?

flash is not working very well on ARM linux, I do not think there is a official port and other 3rd party trys dont work well

really battery life not much more used than any other app running the whole time, of cause if you use the GUI none stop it will drain more but you should still get alot of life
[Android Software Development] Andrioid.:
Awesome! It worked! Thanks! :)

Is there any reason to get the complete linux installer for €2.40?
[Android Software Development] devwithzachary:
well it includes faster downloads of the files from a server not just source forge, you can boot by clicking a button in yhe app so no more typing commands, you will get all future distros and updates first and the best bit is you get this amazing feeling for helping a developer keep releasing amazing stuff (if i do say so myself :-P)
[Android Software Development] Andrioid.:
Alright. I was just wondering if I'm missing out on something. Unfortunately I can't donate. :/

Anyway, here's a picture of Debian running on my phone:
[Android Software Development] devwithzachary:
thats quite alright so long as you enjoy the app etc then my work here is done :)
[Android Software Development] splotz:
Hi Zac,

Can you please post the torrents or link to an overview of all torrents also on the first page ?

So its easier to find and get more people to use it (I also will download and seed stable releases)

I still have problems with the new 12.04 images (full and small).

I did apt-get update and apt-get upgrade and apt-get install update-manager but I still couldnt start the update-manager and firefox kept crashing.

ed.: (The unity icons on the left side arent shown, only grey boxes)

Regards, Splotz
[Android Software Development] barryflanagan:
The same for me.
[Android Software Development] devwithzachary:
Thank you yes was my fault missed something, I have now posted a new fixed version on the market

Ok thanks guys I shall have to download the image maybe something has got corrupt in the upload process, could I get screen shoots of how unity looks to people, and has anyone got it working? prehaps its something to do with older devices, what do you have?
[Android Software Development] barryflanagan:
Transformer Prime running ICS 4.04 (AOKP)

Screenshot attached. Looks just like the very first 12.04 image, before you dumped unity

BTW I also notice that the directory /var/run/dbus does not exist and therefore the dbus socket does not get created.

Also, the init.sh in this 1204 v1 no longer saves the screen dimensions.
[Android Software Development] devwithzachary:
Yes your right...its odd because mine looks fine, but if no one is reporting it working then maybe it is the image, and yes thinking about it your right..it should still ask for screen dimensions but it doenst...hay ho looks like there will be another update soon then
[Android Software Development] splotz:
My screen looks almost the same like Barrys.

Device: Lenovo Thinkpad Tablet, Tegra250, android 3.1
[Android Software Development] Dav_Edward:
Model: GT-I9100

ROM: Stock 4.03

Kernel: 30.15-I9100XXLPQ-CL223505 se.infra@SEP-94 #3 (rooted)

Busybox (installed via 1-click-root): v1.19.2-cm71 installed to /sbin/

The busybox version I have was the one automatically installed with the rooting method I used which I think was 1-click-root. Seems it put busybox in /system/sbin

If I look at the busybox installer, it suggests a version of v1.19.4 and suggests to install it to /system/xbin or /system/bin

Should I install the newer version? if so, which path?
[Android Software Development] devwithzachary:
try isntalling the new versions to /system/bin

To everyone finding unity not working, I have a few reports from people that its working fine so it seems the image itself is fine, there must be something else that is effecting it.

Those that find it not working, is your system partition mounted as r/w ?
[Android Software Development] barryflanagan:
Yes, my /system is mounted rw

-Barry
[Android Software Development] barryflanagan:
I also notice that ssh server was not installed on this image.
[Android Software Development] devwithzachary:
yes I have started to think it would be best to cut back on included programs etc to leave a cleaner install for people to do what they wish (much like to official ubuntu builds). But I think ssh should really be preinstalled your right, it shall be included in the next build :)
[Android Software Development] barryflanagan:
OK, I was mainly checking that this was as it was intended on the v1 image just in case for some strange reason I was using a different image than the latest.

I actually agree on not having sshd installed by default - could open up a bit of a security hole if people do not know it is running and there are default accounts/passwords.
[Android Software Development] splotz:
Maybe its the GPU which is not supported ?

Mine is the Tegra2,

Barrys seems to have the Tegra3.

And Zacs GT-N7000 seems to have a	ARM Mali-400 MP (GT-N7000)

Does this build version support Tegra GPU ?

I can see now the unity icons on the left side.

First I tried to install the newest nvidia driver by apt-get install nvidia-tegra.

But it seemed not to help.

So I thought its the hardware acclerated animation which cant be shown with vnc.

Then I tried this way here to remove the driver (dont know what I changed all there)

ed.: I didnt: "Reinstall xorg completely"

And I got the icons :)

It may be, i can confirm that i have issues with the new 1204 images on my motorola xoom tablet, it indeed has a tegra2, however it runs fine (although a little slow, which is expected) on my motorola droid 3 smartphone, which doesnt have a tegra proc.
[Android Software Development] LinkChef:
Hello! Thanks for the work you put in this. Anyway, I got it working on my Droid Incredible with Cyanogenmod 7 newest experimental/almost stable. So go ahead if you have that combination!
[Android Software Development] Dav_Edward:
I gave that I try. I had to leave my existing busybox install that was in /system/sbin/ alone, but I also installed the new version of busybox to /system/bin/ as advised.

Installed busybox: Busybox v1.20.0-Stericson /system/bin

I do however still get the exact same error as before when trying to boot the ubuntu.sh file. I still wounder if there's something wrong with my kernel.

Here's the log (manually typed it):

net.ipv4.ip_forward = 1
Ubuntu is configured with SSH and VNC services that can be accessed from the IP:

[Android Software Development] splotz:
Hello Zac,

could you please post the Torrents links also on page 2 of this thread

where you link to the sourceforge site (if it is in your interrest).

I think more people would use them then.

Regards, Splotz
[Android Software Development] devwithzachary:
Its very much possible that it is infact your kernel yes, the problem is I have yet to really come up with a sound boot script that can give useful error messages and pin point the problem, right now its a case of it could be a bunch of any of the problems :/

Will do :)
[Android Software Development] robherc:
This looks like the Infamous "my Samsung running android 4.4.x wont' chroot and run init.sh due to permission denied" bug.

Luckily for you, however, we have found a solution to this bug, apparently Samsung devices (and possibly some non-samsung ones running android 4.4.x) don't like a part of the busybox binary that's included with the Complete Linux Installer app. The current-best workaround is to download & run a "busybox installer" app that's made for your device, from Google Play; then rename /data/data/com.zpwebsites.linuxonandroid/files/busybox to /data/data/...../busybox.old

Once you find a busybox whose chroot calls are "acceptable" to your android version & kernel, you should no longer experience that error.

I'm sorry, but Android makes that incredibly difficult to accomplish without killing the android OS entirely while LinuxOnAndroid is running. So, at this time, there aren't any immediate plans to move to utilizing native graphics.
[Android Software Development] bluinitro:
I was able to fix this. Just flashed AGNi kernel and I was on my way to success. I tried SE linux app which didnt really help
[Android Software Development] fastguy:
To use these tools, you need selinux permissive and if possible a samsung kernel which does not block setuid (all samsung kernels do!).

As the android vpn client could not connect to our corporate IPSEC XAUTH PSK vpn, I managed to install strongswan inside the linux chroot and launch the vpn from there.

Strongswan connects and writes /etc/resolv.conf the new DNS values.

Apps in the linux chroot are able to access the intranet through VPN.

But the apps inside Android side, for example the browser, gets stuck while loading our intranet webpage. it does display the page logo, so can get few bytes of info, then gets stuck. Any idea how to enable android side to use the vpn that's initiated from linux side?
[Android Software Development] robherc:
It might work if you add a couple lines to bootscript.sh right after your image is mounted to $mnt:

$bbox mv /etc/resolve.conf /etc/resolve.bak
$bbox ln -s $mnt/etc/resolve.conf /etc/resolve.conf

Then, before all of the umount commands at the end of bootscript.sh, add:

$bbox rm /etc/resolve.conf
$bbox mv /etc/resolve.bak /etc/resolve.conf

That should take care of automatically linking the Android & LinuxOnAndroid resolve.conf files together while LoA is running (without damaging your original Android copy), to at least get you "one step closer" to getting full functionality on your corporate vpn intranet. Beyond that point, I'd really need more specific details on what exactly is, and what isn't, working already with your setup. If you need further help with that, please contact me on the irc channel freenode: #linuxonandroid-help so we can arrange more private communication in case we need to exchange potentially sensitive data about your corporate vpn network.
