XDCMP for controlling desktop

cn flag

Can XDCMP be used to view the current user session / desktop?

I'm running Ubuntu Desktop 21.04 and have modified my /etc/gdm3/custom.conf file so the xdmcp section looks like

[xdmcp]
Enable=true
Port=177

However, whenever I connect to it, it wants me to try and log into the machine. What I am after is seeing the currently logged in user's desktop and being to see what they are doing / take control.


I am aware that there are alternatives to this such as Vino and NoMachine that provide this functionality, but I am specifically interested in XDCMP for this question.

xdmcp is a login protocol, it isn't a screen sharing protocol. It is functioning as designed.

If you want to see the current logged in user's desktop, you will need to use screen sharing software like vnc and enable vncserver in the session you want to view.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
