seems that the -X option doesn't work or not implemented.

thanks

Yep ! It's a must have feature !

Thanks for the app :)

While this would, of course, be the perfect feature, it would require 
implementation of the entire X11 windowing system (which has been done but ends 
up being somewhat slow...)

Yes but what i need isn't to display X11 on my phone but to be able to lunch 
graphical applications on my server from a ssh connection initiated by my phone 
and i can't switch display if the -X option isn't implemented .

DISPLAY=:0
xhost local:username

I can't run these commands to turn display to server without the -X option .
ps: if someone have an alternative solution i will be glad to hear about it .

Switch the display to what? You can't have it display on your phone because 
your phone doesn't have X11. If manipulating the DISPLAY on your server to 
display the graphical programs *on your server* doesn't work, it's not anything 
adding an X11 forwarding feature to ConnectBot will solve.

@rickgha,
make connectbot execute this
export DISPLAY=:0 
after logging in to shell, and your gui commands will be launched on your 
server screen

How do you tell connectbot to execute 'export DISPLAY=:0' after it logs into 
the shell?

@phillip It's a command just like any other that you type in connectbot after 
it connects to your shell.

I would like to reopen this one:

See:

https://market.android.com/details?id=com.theqvd.android.x

The intent that can be used is:

x11://localhost:0

If any feature is needed in the X11 application, I would be happy to implement 
that.

My goal is displaying on Android remotely lauched apps on Linux.

Sooo, is it possible to forward X11 ports with ConnectBot or not ?

I am trying to use the "X server" app but I don't think opening 600X ports 
manually is a good idea.

Also I tried "Xvnc:X/X11", but didn't want to do a VNC.

@kenny my phone *has* x11. See comments 9 and 10.

Please reopen!!!

Similar issue but I'm not even at the -X option. (not to mention forced closes 
but that's for another day)

I've got open-ssh on the linux box.
I did the ssh-keygen -t rsa thing.
I've tried to connect from the phone through Fing (which uses ConnectBot) and 
directly
with ConnectBot. 

In both cases I get connected but the password authentication fails.
I suspect character encoding but for the life of me can't find a setting for it.

If I can get past this step I can try the -X option.

I don't understand why this issue is medium. X servers are available on 
android. I can not use them at work only because I have not found a way to do 
ssh -X (or ssh -Y). The slowness is not an issue: Xserver were working 
perfectly fine 20 years ago and tablets are getting more powerful.

Hi guys!
I tried to export the display like this:
export DISPLAY=ipaddress:0 , also export DISPLAY=ipaddress:6000 .

Gnuplot (on remote machine) thinks about it a while, then says that it is not 
able to open display.

So the question is: is it possible on android to remotely run gnuplot w/ x11?

I'm using android-xserver as x server.

Thanks.

OMGOMG I got it working !
Here is how I did (if someone is still looking for it...)
So, I am using Connect bot along with the app "X server" (which is not really 
beautiful, but this is kind of a proof of concept)

Config "X server":
You need to specify what ip addresses are allowed to display anything in it. 
Add "127.0.0.1" in the "access control" menu. (Yes it's stupid that it's not 
here already..) You can also add the address of your server, but that would 
mean you will be streaming X11 on the network without any encryption (baaaad 
!!) This is it for the "X server" config.

Config "Connect bot":
I guess you all know how to connect to your ssh server using that. But I was 
never sure how to do a port forwarding (yes I am gonna forward the 600X port :/ 
)
So this is a "remote" forward. From the 6001 port (remote) to the 
localhost:6000.
I choose port 6001 because on the server, 6000 is already used by the local 
display (if you have any...) So now server's 6001 port goes on the mobile's 
6000 port (yeay !)
We now have to specify that any X app should be launched on the 6001 port.
Edit your connectBot connection and edit the "Post-login automation" (or type 
this after you logged in...)
"export DISPLAY=:1" and press enter, so it executes it more than just typing it.
This means that what will be executed in this session will be displayed on the 
6001 port of the server, which is forwarded to the 6000 port of the mobile, 
that is accepted by the "X server" app. Voila !
Ho! Just check that the "X Server" app is still runing, it might shutdown when 
you are multitasking.

So things like xterm and xclock are working great. You just don't have a window 
manager... Unless you manage to startx... but I couldn't be bothered so to make 
it work so far.
Also it seems that bigger apps like firefox, thunar (etc...) are missing some 
x11 server extensions to work properly. If anyone is a pro in X11... Maybe 
other X server apps implement those, I have to try !

I did exactly what you suggested, but it says "Error: Can't open display: :1"

But still i cannot run xterm 
What i need (as in several above comments) to run programs like gnuplot, 
xmgrace.. , or any other programs that needs such interface(in the terminal)

As a workaround to display on your Android device (tablet/nettop/smartbook...) 
X11 server (like GPL "X server" application) is :
* launch network connection (wifi, ethernet or whatever.
* get your device IP (for exemple by using settings=> about your phone => state 
(status ?), you will see on this page your IP address.
* launch X server on your phone, 
* connect to the system that will launch X11 application (aka clients) and type 
:

 export DISPLAY=<yourdevice_adr_ip>:0  (for exemple DISPLAY=192.168.0.2:0)

launch your X11 client... et voilà !

Warning everything is transfered without encryption at all, this is a 
workaround until SSH X forwarding is implemented in connectbot (or other 
android SSH client ?).
