With the desktopsharing function of X2go you can have full-access the desktop from somebody else like with programs as Remote Desktop. TeamViewer or LogMeIn. You can see an X2go session from somebody else, but you can also see a normal desktop.
To do this you need access to port 22. So maybe you need to make a portforwarding on your router. Portforwarding is not discussed here on this page.
First you need to install the package x2godesktopsharing on the server (the machine you want to access, this can be a very normal PC):
aptitude install x2godeskstopsharing
Then there is a new application in the menu. I can find it with “Applications | Internet | X2go desktop sharing”. You can start the program with this command too:
After starting the application and some searching, you will find a new icon on your panel. On the top the icon it's blue, and under it is white with a red cross in it. When you right-click on the butten you can activate the desktop sharing there. After activating other people who can login, can access your desktop.
Preparing the session:
Making the connection:
After this you will login on the desktop of the other user. When your monitor is smaller than the other ones, it might be a bit difficult to read.
Be aware, that by selecting 'shutdown' within the shared desktop, the remote system will be turned off!
