[IMPORTANT for me] Startup - Ubuntu Touch Q&A, Help & Troubleshooting

Hello,
I have a question to you. Does anybody know how to change the default GUI that gets loaded on startup?
If I'd know it I could install GNOME Shell on my Nexus 7 on top of Ubuntu Touch.
We could do so much with UT if somebody could help me with this...

Could someone start hacking with me this?
I've install 'gnome' and 'xorg' and if I type 'startx' it tells me that I have no permission because there is no file .Xauthority. How do I get those files?? Please help! I want to get it working...

try chmod 777 xorg or gnome (don't know wich one you want)in terminal or xterminal(my advice:xterminal because it starts with root acces)

Thanks! But that was not the problem. Please look at my thread with the Ubuntu Touch apps in the general section because I can't remember it (it's night here so I should better sleep now than writing this down ).
Maybe you can help me with the last problems (I hope) to get xorg working.

Ubuntu Touch has no xorg drivers, only SurfaceFlinger from Android, so xorg will not run.

Cant run Debian

Hi there, i was trying to run Debian on my pro, but i cant install it! i try two methods, the Linux installer Beta 1.7 (say kernel dosnt have ext and loop support) and the SU terminal emulator way (cant chmod to 4755 any file, even using the su command - from here: http://www.talkandroid.com/android-forums/android-development/1091-install-debian-android.html )...
My pro is ROOTED with latest z4root, i even do a factory repair with pc companion...
Any advice???
Regards!
I tried this as well... no loop is no loop ( required for chroot type runs )
works on a Samsung i5700 I have at work tho...
thnx for the reply, so i can add loop and the ext thing? or we need a custom kernel? , what rom have the samsung?, in other hand i dont know why i cant chmod the files, even using root explorer! regards...
needs a new kernel yes.
i5700 is running samdroid cooked ( forget which version, but added multitouch )
damn :/
now why i cant chmod the files using su terminal emulator or root explorer? maybe is because my sdcard is formated in fat32, regards!
fat32 knows nothing about *nix style permissions, in a way though... all files on a fat32 are set 0777, but not really... heh
For what it's worth, I've just had Debian running in a chroot on my X10 Mini Pro, using the instructions at talkandroid.com, as mentioned by the original poster. Sorry, but as a new poster, I'm not allowed to link directly to those directions. This is with stock ROM, upgraded to Android 2.1, rooted with SuperOneClick.
A few modifications are necessary to make it work. I'm going to try to describe what I've done, but I am working backwards, so it's entirely possible that I'll leave something out and you could suffer disastrous consequences. So please be sure you back up all crucial data before proceeding, and be prepared to accept the possibility that your phone could be destroyed in the process.
First of all, the instructions tell you to run scripts from your SD card, which isn't going to work unless the card has a partition with a Linux-compatible file system. I suggest following the directions as far as step 4. Then replace the "bootdeb" file in the "debian" directory with the modified version attached to this post. Rename it "bootdeb". Then you will have to run the following commands manually, preferably using adb shell, but it can be done in a terminal on the phone. Either way, using the ash shell helps by providing command completion and history.
As root (su):
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock0 /system
mkdir /data/local/mnt
cd /sdcard/debian
cp bootdeb /data/local/bin #note: you may need to mkdir /data/local/bin first
cd /data/local/bin/
chmod 4777 bootdeb
You should now be able to run the bootdeb script to start up Debian.
The installation file says, "Be sure to run /scripts/onetime.sh as root from the shell after your FIRST 'boot'." This will prompt you to set a root password.
At this point, the Debian installation is command line only and root only. The image file needs to be resized before much can be added.
The other files in the Debian directory may be useful, but they all need to be modified before they can be used.
This is only a beginning. I don't know that I'm likely to get very far with it, so anyone else who's inclined to jump in and make this work better is welcome to do so!
edit: correcting grammatical error
Just in case anyone else shares my obsession -- I mean interest in getting Debian to run on an X10 Mini Pro, I thought I should report my progress. Or lack thereof.
Actually, as I said in the previous post, command line Debian works, and that's a lot of power to have available. But it would be nice to get X working, despite the lack of video drivers.
There's a lot of information out there about setting up X with a VNC server on an Android phone, then running a VNC client to access the graphic environment. The source of most accounts seems to be a thread at the androidfanatic forums, with the title "Gnome, KDE, IceWM or LXDE Desktop on your Android!"
(Sorry, I'm still too new at this to be allowed to post links, so this is the only way I can indicate where to find the information.)
I've tried lots of variations on those directions, trying to adapt them to the X10 Mini Pro. And I've had a little success. I can get to the Icewm or LXDE desktop and run the terminal program, but I can't start any programs that use X. Invariably, I get this error:
Error: Can't open display: :1.0
I've run out of ideas, so I'm taking a break from the project. If anyone else is interested enough to try, good luck to you!
For what it's worth, the most recent and comprehensive account of running Debian with X on Android phones appears to be at lanrat.com, in the "android" directory, filename "debian".
@RobbH
Very interesting! I'm waiting a new 8gb card so that I try it! Should you come up with any new progress please report here

[Q] [ Backtrack 5 on LGP500 ]

Hmmm? Well, go and try it?
I tried... at first i thought it should work. As the file system and all are similar
It worked till the 'startbt' but when i entered 'bt' it said segmentation fault
So anyone can tell me please what i have done wrong ( I know the wrong thing is its not meant for Optimus but anything other than that?? ) or tell me how to make it work
Thank you
PS --> My First post on XDA
Ohk looks like something is missing.
do following
reboot your phone do startbt as usual...
after that us
http://forum.xda-developers.com/showpost.php?p=14006091&postcount=15
this script copy script to any location and run it.
sh debug.sh
output will be in /data/local/debug_log.txt
just copy paste the whole file here.
tips you can push the debug.sh file using adb push.
and simmilarly pull the log out using adb pull.
once you are done then post the debug log that can help in diagnostics.

two things.
1) reboot your phone and do startbt and bt again.
post all output here.
2) also segmentation fault could be coz of the busybox chrooting failure.

You really need a bigger screen size to get this working properly.

Java on webtop confirmed!

This guide was taken and revamped with files included from here http://forum.xda-developers.com/showthread.php?t=1067662
I do not take any credit for anything besides revamping the codes to fit new filenames and making the guide a bit easier.
I finally managed to get java to work with firefox. I test out runescape and it works great on minimum graphics setting may be able set higher.
This is a guide to run Java on webtop on any firmware version and more than likely (but untested) any hdmi hacks/mods.
Prerequisites: Rooted phone and minor knowledge of how to run terminals
webtop2sd (http://forum.xda-developers.com/showthread.php?t=1119555) installed would be a major help simply because lxterminal is so much easier to use!
If you refuse to use webtop2sd, terminal emulator on the market will work just fine.
Download this http://www.megaupload.com/?d=PF56FTWD
Extract the ejre1.6.0_27 folder and move to phone
Copy the ejre1.6.0_27 folder to
/usr/lib/
Ingore this code if you are running from lxterminal
Code:
su
/usr/bin/sudo -u adas bash

In lxterminal or whatever terminal
Code:

You can also use root explorer to set permission for the files
Set to this:
read write execute

I will try to make updates to this whenever possible.
If anyone could tell me an easy way to take a screenshot from the weptop I would gladly take some and upload.

I have it running flawlessly. Autosetup actually asks for high but I use safemode.
I have no idea how to post screenshots of webtop but I know its possible.
Also I'd like to add that if you do his method and download the current version... Java runs very very slow. This version is much better.

Quite possible, I'm not a Minecrafter so I wouldnt know. But feel free to try, I dont see why it wouldn't work.
I'll try to get my hands on some screenshots later after doing some digging on how-to's and update this a little bit.
You could try imagemagick. Not sure if it's in the repos though. I'm about to head off to work or I'd try it.
If it's installable just type in a terminal window.
Code:
import -window root whatever.png

Could you post a link to the exact download for this? I could include it in my post.
I dont own a laptop dock anymore by I thought there was a screenshot function built into webtop. (Printscreen key or ctrl+alt+c).
Also I dont think minecraft will work cause it has native libraries for x86.
Very correct, ctrl+alt+c works.
There is no printscreen key though.
Yeah, no luck with Minecraft. It starts to load then just displays a white screen.

Yep, imagemagick works, once you install it.
Works

No problem man.
can anyone give me a setup towards this?
I've currently have xterm working, I've installed synaptic. Iceweasel...
There is a major step im missing. I cant launch firefox off the tab, but I can launch Iceweasel via xterm.

I dont quite know much about the modded versions of Firefox, but I would assume it acts and functions the same as Firefox itself? Ie, there is an addon folder?
That or get your firefox back working by backtracking your Iceweasel.

BHT Installer (Basic Hacking Tools)

Hey guys, I came up with a basic set of tools which I find useful. You may redistribute , include in any custom ROMs and/or distributions.
This includes:
Rewrite /default.prop for ADB
Install and deploy busybox in /system/xbin
install bash, ipctool, strace, tcpdump, and viewmem binaries.
To install, you must be rooted.
Unzip the attached file
place it on your nook.
cd to the folder you installed
Run the following
Code:
sh /sdcard/BHT/run.sh
Please note, I use Android Market app QuickSSH to get into my nook terminal, your results may very.. I hope someone else grabs these files and makes it all more user friendly. I've got too many other things going on.
I encourage other developers to include these valuable debugging tools in their packages.
You, sir, are a monster! You get my vote.

I can turn this into an apk, if you don't mind. By turn on adb with this method, adb will be rooted and the device will still be allowed to sleep?

My vote too. I just hope after you win that you keep up the great work on the Nook Tablet. The last two weeks or so have looked very promising towards getting custom roms on here and a lot of that has to do with Adam's hard work along with a few others
Nearly all of these are already in snowball-mod, but I'll include ipctool, and viewmem for the next release.

How did you get default.prop reread into memory? The only think I can see is the 2nd init hijack? Am I missing something a lot easier?

Note, I said "nearly all". I don't really see though how changing /default.prop would keep over reboots... rootfs is stored in memory and recreated every time, isn't it?
I've added the binaries to NT Hidden Settings. I have not implemented /default.prop swap yet. I have to play with hijacking init before I do. Thanks again.

cool. where are you hosting that binary? I currently have a mirror set up at nook1.adamoutler.com for easy access... When someone gets a new device, they need to download 3 things onto their device to make it a real tablet.. nook1=hidden settings, nook2=homecatcher, nook3=market.. I may change 3 to launcherpro, but hidden settings is the number1 tool required for the nook Tablet.

Homecatcher? I mean, I understand if you want to keep using the B&N store and stuff, but if you don't care about the B&N stuff, then the hacked SystemUI.apk is a way better option than Homecatcher.
But then, you're advancing "launcher pro", while I would more generally say "any non-B&N launcher"...
I added another option to nt hidden settings to run adb as root. It doesn't require a reboot and it automatically turns off auto mount. I am using nemith's adbd.
remount / as rw
stop adbd
replace /sbin/adbd
remount / as ro
setprop to turn off auto mount
start adbd as root
It's not persistent after reboot, but it works and doesn't kill the battery. I am not going to bother with hkvc's hijacking init method, because it looks like you, hkvc, bauwks, and nemith will be able to replace the os soon. Thanks.

[Q] Howto upgrade the busybox properly ??

Hi,
I tried to upgrade the busybox with different manner (busybox, busybox installer, manual installation from xda), but no one works properly.
Each time i broke the original Archos busibox, so i lose the adb shell.
Can someone explain to me the good way to upgrade the busybox?
Thanks.

Google? also XDA has a great search feature have you tried that? :silly: Any particular reason why you want/need to upgrade busybox?
Hi,
As i said, i tried the different busybox installers and the installation was ok, but i each time, i lost the shell from adb.
That's just my problem.
So i just want to understand why the upgrade of the busybox broke the original archos busybox?
Moreover some application need to have other busybox installed.
Regards.

Ahhh right, the quest for knowledge Your problem is as much to do with adb ( /sbin/adbd to be precise ) as it is to do with busybox, firstly you've probably wiped out the symlinks in /bin, especially /bin/sh which is the location that adbd on archos looks to run the when you do adb shell from your desktop. This is not the default location which just about every other android OEM adheares ,that is /system/bin/sh.
If you are going to upgrade the archos busybox be aware that a large number of symlinks back to /bin/busybox exist not only in /bin but also in /usr/bin /usr/sbin
Archos for reasons I still haven't fathomed, really went to town on restructuring and customized Android on the platform level.
A little tip if you've got more question, to save you bumping threads , which really does upset some folks round here... you'll probably get more more if you add more details, such as error messages etc. Saying " i lost the shell from adb." doesn't really help anyone who might be able to offer assistance. There about 10 different ways adb can fail to connect, Did the device disappear from the list or report as offline. or even come up with the message "- exec '/bin/sh' failed: No such file or directory (2) -".??
Hopefully that's helped.
Hi SirOrch,
i don't know why you loose your adb shell, but concerning busybox... the things on Archos tablets are like this:
Basically on a non rooted device we got a squashfs image mounted read only.
This image contains the stock busybox compiled by Archos (sharing system's uclibc) with limited functionality,
but containing enough tools to handle the daily job.
The path to this busybox is "hard-coded" as well. It's location is /bin which is the second entry in the path environment.
You might check that by typing printenv in your console.
The first entry should be /data/local/bin on your device.
So if you like to replace stock busybox with an advanced one, you should make sure that it will be installed to /data/local/bin.
Often there's no need to use all this apk Android Market stuff to get a proper busybox installation.
Sometimes it's little better to really understand what's happening under the hood.
Most busybox app's are statically linked, because with a static binary you don't have to take care of the device's libc or uclibc.
So you might easily extract on of the apk's or get one from xda-developers.
There are many floating around in the end.
If got one push it to /data/local/bin with adb.
You might need softlinks in this directory as well. This could be done by hand as well.
Anyway if you are a lazy person, who doesn't care about what's happening, go to the market install busybox.
Then check at /data/local/bin if it is there.
If it got installed elsewhere, some commands will still use stock busybox.
Extended commands might then use the installed one.
So check it out...
EDIT:
... aaaargh again simultaneous posting.

Hi gentlemen,
Thanks for your help and sorry to forget to give you the error message i had:
the message was : - exec '/bin/sh' failed: No such file or directory (2) -
After investigation i found my mistake:
- In manual mode, i forget to change the ownership of busybox to root in /bin.
- when i tried to use any application from the market, the busybox was well updated in /system/xbin but the application also delete the busybox in /bin and don't change the symlinks in /bin. That's explain why adb shell won't work.
Regards.
SirOch
