Dear All,

I am following up with my previous post as I am still stuck and unable to use X2go.

I have a crashed session and I am unable to close.

Does anyone have any suggestion?

Thanks! Ilaria

I have used it successfully for a couple of weeks.

Then, once, I got the following error message while attempting login (windows10):

Failed to start X2Go Agent session with ID xxxxxxx. X2Go Agent terminated unexpectedly. Aborting session startup.

I tried to

restart PC unistall-reinstall delete session-recreate session exit putty-re-entering

I have no more attempts to do.

I have used other clients before, and for one of those this sometimes would happen.

Sometime vcxsrv crashes and leaves the remote x2goagent in a bad state which results in another crash of vcxsrv on reconnect. The only way to fix that is to kill the remote session (the remote x2goagent process) and start a new one. From your text it is unclear if you have tried that.

I did the following in the x2go GUI: Session-session management-terminate session I also uninstall and re-install X2go, but the crashed session was still there.

What I was doing was to -kill geometry in putty and then re-do one.

What do you mean by that? I was using a command line in putty terminal that would kill anything pending and then I was re-configuring the geometry upon the next re-start. I do not remember exactly what the command line was about, but I remember it was using -kill and -geometry flag. Sorry I wish I could be more specific. Anyway I was using TightVNC and not X2go. Likely it does not applies.

Is there something similar I can do here?

You can try to use mobaxterm to connect to your server and see if you can run "x2goagent :1" there. If that does not work, that's the reason for the connection problems. If it works, then we need to search the problem elsewhere.

I cannot use mobaxterm, because my institution (and relative cluster I am trying to connect to) only supports X2go.

I tried to visualize the Archive of this mailing list but I could not find a way to search previous posts.

I had seen the list of Archived posts (https://lists.x2go.org/pipermail/x2go-user/). I started searching by clicking on the first Thread or Subject, then the second, third, and so on... I was wondering is there was a way to visualize them all in a long list so that one can ctrl-F keywords.

Thank you again for your kind support.

Ilaria

Thank you Uli for keeping the ball rolling!!!

Following your suggestion, I pgrep -f x2goagent And got a number of ongoing processed that I am not allowed to kill. e.g. pkill: killing pid 133596 failed: Operation not permitted

So I tried to figure out if any of those were mine:

pgrep -f x2goagent -u sani pgrep -f x2goagent -s sani-67-1637314001_stDXFXF_dp32

But no line appeared

Is it possible that my crashed session is not listed there?

Thanks, Ilaria

In German the button means "Delete session" (so this is likely to be a translation mistake), and it will (only) delete the session configuration on the x2goclient side, not stopping any running session.

putty to your server, run pkill -f x2goagent -> will kill all _your_ x2gosessions.

You can try to use mobaxterm to connect to your server and see if you can run "x2goagent :1" there. If that does not work, that's the reason for the connection problems. If it works, then we need to search the problem elsewhere.

Mobaxterm is an alternative to putty which comes with an embedded X server. The only thing you need is ssh access to the server, which you (obviously) have.There's a portable version of mobaxterm that can be run without installation.

Well, I am not aware. But you can use google to and limit the search with "site:lists.x2go.org"
