So work is happening to accomplish replacing the webtop with a gentoo base img.
My proposition is to create a very slim gentoo so you guys can add as you please
So im making this post to hear from you guys what you would like to see in the Gentop.
So far my idea would be very basic.
Openbox + terminal + conky
and of course a browser.
So tell me, if this was your gentop. what would be there!?
In addition to your suggested items for a "gentop", I'd like to see more file viewers that take advantage of the lapdock screen resolution, like PDF, (Open)Office docs, even EPUBs.
I would add in some sort of rdp, vnc and ssh clients.. I could really use those. Thanks for all the hard work you do
Sent from my MB860 using XDA App
Could you guys prepare a version with synaptic and lxde? Im sure there are people interested in the fastest webtop experience possible, but have 0 skill in linux encoding. With that, we can customize as we please with easy visual reference.
About ssh clients -- it should be mentioned that there is already an "rsync" backup for android freely available in the Android market. It installs rsync and dropbear ssh clients. So with a terminal app, your webtop will have access to cli versions of rsync and ssh. Then just do a symlink from the installed apk into /system/xbin/ and presto instant ssh and rsync.
Would we still have a phone view within gentoo like we have in webtop?
If not, would the phone screen remain accessible while docked?
How would this handle incoming phone calls?
Okay guys I have been looking around the internet and I am bumbfounded by all of the crap that you have to sift through to get a simple answer.
I am a Student in a Robotics Team at a community college. I am trying to impliment the Kinect and Android powered phones/tablets into our program, but when I try and find the topic I get overwelmed by all of the technical jargin that they have on these sites.
I am a senior in Electrical Engineering Tech. but have little programming skill. If anyone could help me with this robot that I am building I would be extremely greatfull.
I am trying to use these two sites for inspiration and one is even a how to site, but I cannot figure out what it is trying to say.

I would like to just get the interface working but I have plans on either controlling a Propeller microcontroler to move forward and reverse and/or just controlling a paint-ball gun so that it can move up and down.
If anyone can help please do so. I know this is, what I believe to be, a hard task to jump into, but know that if you do help you are helping the Robotics Team expand their horizons in a small town in southern West Virginia.

I found this and tried it with a copy of chroot on my Acer Iconia but it doesn't detect that I have a kinect connected via the usb. I believe that the usb is not implemented over the bridge where I am viewing the ubuntu using the VNC viewer.
source: http://openkinect.org/wiki/Getting_Started
Also this will not work with the new Ubuntu 11.10 so I have no idea if this is even a good way of even doing this anymore. I know it worked on 10.10.
I am not sure what help this will be, but you may want to check out the FIRST Robotics competition forums. The task this year is to build a robot that can shoot basketballs from input delivered via Kinect.
http://forums.usfirst.org/forumdisplay.php?f=1537
It may not help you get the kinect stuff running on your A500, but it may be useful in working with it after you get it up and running.
Thank you Psichi for your help in the future. I also see some files that I could use with the windows problems that I have been having with it. lol.
I really only need help with getting the Ubuntu chroot on my Acer Iconia A500 to be able to read something when it is hooked into the USB slot on the side. It is running perfectly but the connection is not there.
You have the power for the kinect unit plugged in as well right? A developer on my team at work mentioned the unit can't do power over usb on anything other than the new xbox.
I know it is a stupid question, but the amount of times I forget to rule out the simple things are more than I would like to admit
Sent from my tomato filled Evo
Yes I went out and bought a 30 dollar plug in that separated the USB and the power. I had this working on an older version of Ubuntu but it won't connect via chroot now because the USB functionality doesn't bridge to the emulated Ubuntu...
You should have a look at hirotakaster.com he has connected Kinect to Android using OpenNI 1.5 and 2

How to host your own website on a Raspberry Pi
Requirements
Hardware:
Raspberry Pi
USB power cable
Ethernet cable and modem to connect to
HDMI cable (temporary need)
Monitor (temporary need)
USB mouse/keyboard (temporary need)
Standard SD card
SD card reader on your computer
Software:
Raspbian image - Debian based OS for Raspberry Pi
Lighttpd - lightweight webserver that is extremely easy to set up
PageKite - makes local websites or SSH servers publicly accessible in mere seconds, and works with any computer and any Internet connection.
Also you will need to buy a domain for your site. I purchased mine through hover.com, but there are many to chose from.
First you need to setup the SD card on your Raspberry Pi.
The SD card is the harddrive for the Raspberry Pi, you'll be installing Raspbian which is a derivative of Debian. If you are familar with Linux you'll be right at home.
Here is the guick start guide for Raspbian:
http://www.raspberrypi.org/quick-start-guide
Install the latest "Raspbian" SD card image from here:
http://www.raspberrypi.org/downloads
Just follow the instructions to download the image and install it on your SD card, once we actually boot the Raspberry Pi you will set it up.
Now, here is where you temporarily need to have a monitor, keyboard, and mouse that you can use to run your Raspberry Pi.
If you don't have a monitor, mouse and keyboard, you can set up your Raspberry Pi in headless mode. Here is a link to to this, although I did not utilize this method:
http://www.penguintutor.com/linux/raspberrypi-headless
Now plug in the ethernet from the Raspberry Pi to the modem, HDMI from the Raspberry Pi to the monitor, USB to your keyboard and mouse. Plug in the SD card that you
installed Raspbian and last plug in the power. Plugging in power is how you power on the Raspberry Pi. Go through the on screen setup, be sure and change the password,
turn on SSH, set the date/time and any of ther other setup options that you think you'll need. Complete the setup and pat yourself on the back, you are on your way.
Next step, setup a static IP on your router so the Raspberry Pi always has a static IP in your home network. Here is tutorial that I followed for this
step: http://www.penguintutor.com/blog/viewblog.php?blog=6306
Once you complete this come back here to continue the setup.
Good job so far. Let's use some of our Linux skills now(I'm a huge Linix fan, it's all I run on my PCs), don't worry, it won't hurt.
Open the terminal and run the following command:
sudo apt-get install lighttpd
Did you press enter at the end of that last row? You should.
Now run the command:
sudo reboot
While your rebooting here is something to read:
lighttpd is a lightweight open source webserver. It is pronounced "Lighty" and it will listen for requests on port 80, when it receives a request
it sends back the requested webpage.
Ok and we're back. So you should be rebooted now so let's check to see if lighttpd is doing it's job. Type in the IP that you assigned to your
Raspberry Pi, for instance 192.168.1.10, on your browser. You can do it on your computer or on the Raspberry Pi's browser, it's called Midori.
You should get a webpage showing that lighttpd is working. The file that is being displayed is sitting on the Raspberry Pi at /var/www/ and it's
named index.html. This folder is where you will place your website. You have created your website already right? If not, you can do that once you
have completed this setup. I used a starter page from http://www.styleshout.com/.
Ok you're doing great, we're getting near the end.
Next we are going to set up an account with PageKite. PageKite charges $36/year for an account. There are free options like Dyndns, but I have
Verizon fios and am forced to use their router, thus my Dyndns did not work well for me. If you wan to use Dyndns, you can set up a free account
that should work for you.
PageKite is easy to install, just visit their page from the Raspberry Pi and setup an account and install the software. You will be installing
the Linux version and the site walks you through all the steps. Make sure your account id is NOT the same as the site you are setting up. You will
use the site name also as a secondary pagekite. Once you have your account set up with PageKite, you will need to follow this guide to setup
PageKite to point to your own doman: https://pagekite.net/wiki/Howto/CnamePageKites/
For step 2 above, if you went with hover.com, you'll need to add a new DNS with the following format:
Hostname: www
Record Type: CNAME
Target Host: sitename.accountid.pagekite.me
Complete the CnamePageKites setup and then you are done! Your website is now live on the web! See that really wasn't very hard to do.

You need to do

Also try sudo apt-get install -f lighttpd
Static up setup for yoir pi is must for this to work
I wonder if it can support some light php tasks and maybe a database?
Also is there a posibility to connect 2-3 raspberry Pi and do some kind of loadbalancing. For example one could be the lighttpd server, an other server could host the files and do all the php work, while an other could by the mysql server.
Could this be done, how would you go by connecting all that together, through a router?

Seems a pretty simple setup, but you missed out a step.
You need to port forward port 80 on your router/modem so that your modem sends all incoming port 80 traffic to your Raspberry Pi.
Also, you should use Apache which is much faster, and the original open source web server.
@jji7skyline, on what did you base your opinion? Check this:

I just prefer Apache because of its wide support and speed, but maybe I was misinformed about its speed on ARM devices.
LAMP is a good package if you want PHP, MySQL and PHPmyAdmin.
what i would suggest is better go with NO-IP or similar stuff !!
they have nice ip update clients ! not only will you save money , it will make easy to manage the accounts as they have good apps for Linux !

i guess yes !
You can setup ip and port forwarding to make the same make happen !
like, may be, you can set up a My sql server at lan and then setup a port forward to that r-pi and necessary stuff !!
then your man server can issue requests as necessary!!

Have been using Apache for a damn long time ... very comfortable with the same !!
but in these recent years even i have been ranted over to use Lighttpd seems it is friendly with processor !!!
Also suggest no-ip. I use no-ip on the NexusQ site server. It cuts down on cost and you can take your server with you. I've even run it on a mobile server (read phone) that was wifi tethered to my phone while in my car. The same could be done from the RasPi as well.

I first used the Raspberry Pi for XBMC, RasBMC and it worked great. I did not use it to stream anything locally stored but I believe it would handle that just fine.
Sent from my Nexus 7 using xda premium
I've used the Pi to stream things from a share on a desktop computer and found that it worked wonderfully (as long as the connection could handle it). I've even done HD streaming with little to know issue at least streaming wise. I was using OpenElec at the time, but I imagine it's not different on Raspbmc, if anything it should work better.
Edit: I also want to note I constantly Stream things via Hulu or Youtube. These also work great as long as your connection can handle it. They can be a little slow while "loading" but once a show gets going they usually do just fine.
Wow an entire website hosted on something no bigger than my phone...EPIC
There is also the option to send your raspberry pi to http://www.edis.at/en/server/colocation/austria/raspberrypi/ instead of using your home internet connection. Higher availability and better speed. for free. I haven't used their service, though, so i can't say whether they are ok.

My respect sir, very good use for a raspberry pi, I tip My hat to you
If you don't understand what ssh or vnc is, please don't attempt this.
I am able to run Kali Linux armhf on the 13.3.1 by following this guide. It can run other distros too.
I can confirm it is working 100% and runs very smooth. Here is a link to the Linux Deploy app. You need a vnc app or a ssh app to interface with it. I recommend Real VNC Viewer. Instead of connecting to your private ip, just connect using your loopback 127.0.0.1 It is faster.
I hope this could be of some use towards cracking the bootloader. Comments, questions, discussion wanted.
Nice idea but what can you really do on Kali that you can't do via adb shell?
PS putty ftw!

Repurpose a device
I would really like to get a different OS on my device or even do a GRUB bootloader kind of thing which will allow Android or another OS. I want to repurpose a tablet for my car project and I don't want to use Android.
I have done the VNC thing in the past with Ubuntu and it was horribly slow. Anything emulating on top of an OS will be less than optimal. I have used VMPlayer and VirtualBox before on a regular desktop and they seem ok. But still I'd like another OS that will be fast on boot up and ready to go in the shortest amount of time.

This is very interesting. Has anyone managed to get Mer working through Linux Deploy? Having Plasma Active running like that would be pretty awesome. Other DEs aren't really optimised for touch the way Plasma Active is.
EDIT: Actually, it might be possible to get Plasma Active running via Gentoo, as they have an overlay for it. Still experimental, but then what isn't experimental at this point

You use a vnc app on loobback address(127.0.0.1) to connect. It is the fastest emulation I ever had running on any device. This is perfect for me if i can get a keyboard working. If you lower the resolution of the linux guest with a ui like lxde it is very easy to use it as a touch interface.

Try it out on the loopback address 127.0.0.1 It is blazing fast with ui like lxde or xfce. Fastest I ever seen on a tablet/android.

Yea, thanks. I'll read a bit more on Linux Deploy to see how it works. And I'm very familiar with Gentoo (have three Gentoo devices here), so setting it up shouldn't be a problem. I also asked on their IRC, and they said Plasma Active should theoretically compile on Gentoo ARM, but nobody ever tested it. Sounds like a good opportunity to do just that!
Got to run Gentoo, although it required a bit of effort. Since I want Plasma Active, I didn't choose any GUI (I need to set it up manually). However, the problem is that SSH wouldn't run, either, citing that OpenRC wasn't started itself, and that I had to execute touch /run/openrc/softlevel in order to get it to start. Which is nice and all, but it's a circular dependency: to create the file, I need to log in through ssh, and to log in through ssh I need to create the file. So I ended up doing this:
Create a bash script file with that line
Upload it to the device (I put it in the downloads directory)
Do a "chmod 777 /datamedia/media/0/Download/<myscriptfilename>.sh"
In Linux Deploy:
Enable Custom mount (leave the path default)
Enable Custom startup
Set Script file to "/mnt/0/Download/<myscriptfilename>.sh"
That allowed me to create that file and start sshd correctly. So now I can log in via ssh, yay!
It makes me wonder, though – is there a support forum for Linux Deploy in English? Their main forum seems to be Russian...

I actually took concepts from Linux Deploy and Complete(??) Linux Installer, and built a set of scripts to do all the chroot work without needing an Android app. Since I primarily use the terminal, running everything from the shell is much easier than using an app.
Using something like Android Terminal Emulator, you do not need ssh on the android side at all. You simply su to root and run a chroot command:
chroot <linux-mnt-pt> /bin/bash -i
or
chroot <linux-mnt-pt> /bin/su <user>
or
chroot <linux-mnt-pt> /bin/login <user>
The last option requires typing a password, but since it's a login, it sets up your environment correctly. The other two inherit your Android PATH (among other things), so you have to set PATH by hand or use an rc file which sets it from scratch.
Personally, I find even LXDE much too slow for regular use over vnc. Most of my interest revolves around emacs and gcc, which both work great in Android Terminal Emulator.

Ah, thanks for pointing that out. His issue list is in English, and that's exactly what I need!
I talked to people over at #systemd to see if it would be possible to have systemd launching things in a chroot, and unfortunately it seems to be impossible for the Kindle Fire HDX 7, because its kernel is not compiled with PID namespaces that systemd requires to function, and we don't have any means to compile custom kernels as far as I know. It's too bad, but I guess I can cope with OpenRC for now.

Interesting, although I do prefer an app (it's really quite convenient). Also, as far as ssh goes, I do prefer having that running over typing things into the terminal using the touchscreen.
Overall the experience of running Gentoo on ARM is interesting. The Snapdragon 800 is really quite a beast, but rather peculiar. There are often delays before my input starts to be processed, but once it does, it runs very fast, until it goes idle again. And the speed at which it compiles things is amazing. It's also nice that I can use all of those nice optimisations (I'm using -march=native and -mfpu=neon-vfpv4, with the neon USE flag enabled; I'd like to set -mcpu to something specific, but it doesn't seem to have Snapdragon as an option).
Ubuntu os
Maybe sometime we would be able to get Ubuntu os on our tabs.

You already can, although it's limited to the desktop version (which isn't any good when it comes to touchscreens). Not sure if Ubuntu Touch will be available at some point. But eventually Ubuntu will ship Unity 8, which will be more touch-friendly.
This is all great news!

I don't think -march=native is doing anything there buddy.
GCC doesn't officially "support" Krait (yet), nearest I can see would be Cortex-A9 which uses the same scheduling model (albeit with 3 less pipeline stages) as a Krait. Interestingly, LLVM/Clang has just patched in a krait -mcpu target, if you can use that. To be honest you'll not be gaining too much as, IIRC, the main difference between a Krait and an A9, in compiler specific terms, is vfp4, but you're setting that with the -mfpu option anyway.
My point after spouting that gibberish is to not sweat it, lose -march, change -mcpu to cortex-a9 and you're golden. At least until a krait mcpu target for GCC...

Nope, -march=native sets -march to armv7-a, which is close enough. The point in using it is that as soon as GCC gets better optimisations, -march=native will use the more optimised choice, without manual intervention.

Hi all!
Someone of you might already know about the virtualization engine ExaGear Desktop that enables running of x86 apps on ARM boards. And now ExaGear can be run on Raspberry Pi 2.

For owner of previous versions of Raspberry Pi there will be a special vertion of ExaGear. Submit pre-order request in order to be the first to know about this release:

That's pretty impressive.

Thanks! We'll keep you informed about updates.
Bty there is an interesting and very detailed article about ExaGear Desktop on ODROID board written by independent user:
http://magazine.odroid.com/assets/201502/pdf/ODROID-Magazine-201502.pdf
this sounds pretty interesting, i have been looking for a solution to a problem at work, we need 30+ work stations to do simple data entry through a Microsoft access frontend. is it possible to run MS access in ExaGear? and would it have any trouble linking back to an SQL server?
the hope is to buy 30 Pi's rather than having to shell out for that many PC's, if something like this works it would save us a fortune
Thanks

You can if your Access version runs on Wine[x86].
A processor emulation on the rpi should be very slow...

Exagear has very efficient bt core which utilize ~50% native performance. But rpi itself is not very fast device, so it depends on software requirements.
