Let's say I want to share a screen with someone. I want this person to be able to control one application in this screen (the application is started with my user).
To do that I am doing the following: - Starting a new X server with Xvnc in DISPLAY :2 - Running the application in this display - Giving remote access using VNC
Doing so, will the person be able to open other programs or have access to my user? Is this a good solution? If not, what is a better/safer way to achieve what I want?
