Laptop now using Kubuntu PC...

systemctl restart x2goserver

systemctl status x2goserver

sudo x2golistsessions_root | awk -F'|' '{ print $2 }' | xargs -I % sudo x2goterminate-session %

sudo x2golistsessions_root: Lists all active or suspended sessions for all users.

awk -F'|' '{ print $2 }': Extracts the unique session ID (which is the second field, delimited by |) for each session.

xargs -I % sudo x2goterminate-session %: Passes each extracted session ID to the x2goterminate-session command, forcefully ending each session

OR start new session on the client

Terminating Individual Sessions from the Server 

If you need more granular control than the automated script:

    List sessions to find their IDs using:

    bash

x2golistsessions

# or as root

sudo x2golistsessions_root

Terminate a specific session by its ID (e.g., someuser-50-1440778845_574):

bash

sudo x2goterminate-session <session_id>

X2Go has limited or poor support for advanced OpenGL features. Try an alternative remote desktop protocol (VNC/TightVNC): Many users report success running Stellarium over VNC solutions like TightVNC which handle graphical applications differently than X2Go's protocol.

    Install a VNC server on your host and a VNC viewer on your client machine.

    Connect via VNC
