X2Go relies on NX libraries with SSH for secure and efficient sessions, while NoMachine uses an optimized NX implementation focused on graphical performance.

Session Architecture

X2Go creates virtual X11 sessions, meaning each user receives an independent remote desktop environment that runs separately from the system’s physical console. This architecture is useful in multi-user environments such as shared servers, development labs, or academic systems, where multiple users can connect simultaneously without interfering with each other’s sessions.

NoMachine supports both virtual desktop sessions and connections to the active physical desktop. This allows users to either start a separate remote session or directly view and control the same screen currently active on the remote machine, which can be helpful for remote assistance, collaboration, or troubleshooting.
