how can i convert my system into a remote desktop server

Question

We are a small team having limited resoueces but large projects and ideas. I use Ubuntu 12.04 on my system. I want to make my system usable to others also. Hence I want to convert it into a remote desktop server so that even while i am working on ubuntu they can use my system ( without effecting my work) just by logging in. Is it possible?

Note I want to allow multiple user sessions at once

Thank you

Answer 1

For the Ubuntu colleagues, create user accounts on your machine. Then have them login with ssh -Y and run their desired application. The -Y option allows the visual output to get tunneled to their box.

If you want your colleagues to have a full desktop environment, you could enable XDMCP on your box, and have them run one of the client solutions described in the Ubuntu XDMCP documentation. Note that running Unity or Gnome this way is pretty much out of the question, you could however give them a lightweight desktop environment such as XFCE.

There is a program in Ubuntu named Desktop sharing. You can access it from dash (press super key).

Edit: For a single user on remote Ubuntu/Linux only one user can be logged on. If you want to share your screen try tools like TeamViewer and a greate chrome extenssion from https://chrome.google.com/webstore/detail/chrome-remote-desktop/gbchcmhmhahfdphkhkmpfmihenigjmpp.
