Desktop Screen Sharing (VNC)

[limbei]

Hi,

Does anyone knows how to share Desktop Screen via VNC?

I have a python program written with GUI output.
This program has been set to run immediately after the Pi is powered up.
I wish to be able to view the GUI output remotely via VNC.

I am currently using vnctightserver.
However, vnctightserver only allows remote control and not screen sharing.
Example, whatever I have done on the client will not be reflected on the host and vice-versa.
The process can only be verified through the terminal using 'ps -A'

I read about vino-server. Its not supported anymore.

Any help is appreciated. Thanks.

Sorry, same problem.

Im searching the net for "desktop sharing" for days now but every article or tutorial means remote access.

But I really need to interact parallel to the remote user to give support. Therefore I need remote access to the users screen, mouse and keyboard.
All "solutions" I found in the net provide a second session via VNC on port 5901. It's driving me crazy.

I don't want to create another session than the one running on port 5900.

My targets are:
- to have a lean solution without big workaraounds, in the best case via VNC because of good support in Android and Windows
- to have access via internal network, no internet needed
- to get access already at startup - I'd like to see already the login screen of the remote user
- to have optionally the ability of access via internet (must be able to deactivate)

So, pls. help with a solution you can recommend and maybe give a little bit support with configurations.

Thank you in advance.

Whilst, unlike "tightvnc" (which open a new "desktop session), the "x11vnc" server will forward the Pi's (current?) physical (X) display to a remote computer (which has X support) I suspect that that will not solve your "problem". This is because I think the connection to the remote computer has to be established before forwarding the display and then running your python GUI. (ie. I'm not sure that all of those things can be done as a "boot-time process" - but I could be wrong). To run an (X-based) GUI app. does not necessarily require a VNC server, just X-forwarding which can be provided via a ssh connection (assuming the client already has a local X-server running - easy if it's also a Linux box). I often use PuTTY to ssh in to my Pi's with X-forwarding enabled from my Ubuntu netbook and that's sufficient (FWIW, some brief notes are here: http://www.cpmspectrepi.webspace.virgin ... aspPi.html.) but this is always done after the Pi has booted up.

I'm using vino-server. It's in the Raspbian repository. What do you mean be "is not supported an more"? It's available and does exactly what you are looking for.

I use RHUB screen sharing appliance for desktop screen sharing & online meetings. It allows me to share my desktop with all my meeting attendees.
