Recently I installed x2goserver on an Ubuntu Mate 20.04 machine and x2goclient on my CentOS 7 workstation. I configured the session with "[X] Try auto login (via SSH Agend ot default SSH key)" as I have an SSH key installed on the remote machine. It connects fine over my LAN and I find the CPU utilization on the remote machine much lower than with x11vnc which I had been using. Her are my client related questions...
What is the CORRECT way to disconnect from the remote machine and leave the remote session (and the programs on it) running? The goal being to be able to check back later on the status of the work which the remote machine is performing.
How does one connect to more than one remote machine? I have only been able to do this by loading an additional x2goclient for the next remote machine. This seems to waste a lot of real estate.
I explained my adventures in detail on linuxquestions.org but did not receive any advice. https://www.linuxquestions.org/questions/linux-software-2/x2go-how-to-discon...
Thanks,
Ken

You can right-click on the x2go icon in you tray and select to suspend the session. Or you can close the session window. It will then ask you if you want to terminate or suspend the session. Of you can send a HUP signal to the x2goagent process of you session (on the server). Finally you can run the x2gosuspend-session command, but you must first determine the session id from x2golistsessions.

For x2goclient there's currently no other way that to start it a second time (but you can specify the session to use from the command line).Or you can use pyhoca-cli (and maybe pyhoca-gui). I personally have no experience with the pyhoca tools.

I do not have a "tray" on Mate per se. I do have a notification area on the top panel but x2go does not show there (client machine). I do have Suspend and Terminate buttons on the Session information window on the big blue x2goclient waste of space area. If I click Suspend it does close the window which shows the view of the remote machine. By connecting to the remote machine with an SSH terminal and examining what is running it appears that the remote SESSION is running, not suspended (which my research lead me to believe should happen.) And I can reconnect to the remote session which is a good thing. Thanks.

On Linux I can launch many instances of the x2goclient. However, each instance of the x2goclient can only connect to ONE remote machine. I am spoiled from using vinagre to connect to conventional vnc sessions. It presents them in a tabbed interface. Very space efficient and easy to switch between remotes.

x2goagent will always be running for the session, this is the session's X server. "Suspended" means it will use less cpu cycles.

Yes, x2goclient should have something like that. Someone should code that...

Thanks again Uli,
I will have to do some experimenting and monitor CPU usage. Other than the client interface I am pleased with x2go. It was VERY easy to setup and seems very efficient.
I have used vnc4 and Tigervnc going back to probably Red Hat (not enterprise) 8 or 9. I always thought it was cool to be able to connect to a remote PC and do my business without having to interact with the physical console. Sort of like a REAL (mainframe) computer :-) The biggest stumbling block to using these products has been the xstartup script. Some of it I understand and some of it I have no clue. Over many years I have taken a working one, moved it to the next OS version, looked on-line and tweaked it until it worked. I had vnc4 working on Ubuntu Mate 18.04 but it is not available on 20.04. I have used Tight/Tiger on CentOS 6 and 7 but my xstartup would not work on Ubuntu.
Yesterday I found a tutorial on setting up Tightvnc on Ubuntu 20.04. The example used the XFCE desktop. I followed it and it worked! I tried to clone the process onto my Ubuntu Mate 20.04 test machine. No go. I started stripping lines out of the xstartup which I did not understand. I ended up with one new line from the XFCE example and 2 from my old script which worked on 18.04. The vncserver runs and I can connect to it !!! I get a couple of pages of log from the startup - mostly error - but that seems to always happen.
CPU utilization by the Tightvnc server seems to be in the middle. More than x2go but less than x11vnc.
Again my thanks,
Ken in North Carolina, USA
