OK, yes, that seems to have fixed it!  Thank you so much!

sudo /etc/NX/nxserver –disconnect <username>

is exactly what I was looking for, and worked perfectly.  Thank you very much!

This seems to work perfectly!  Thank you!

[adamltaylor]

fisherman: Thank you for the suggestion, I will try that!  Sounds like exactly what I was looking for…

 

[adamltaylor]

katpan: Thank you for those suggestions!  I will try those soon.

Hopefully one or both of these methods will lead to me not losing my X session.  If that turns out not to be the case, I’ll follow up.

[adamltaylor]

It is understood that this is a privacy feature and that, therefore, one can’t implement something like “Press Ctrl-Alt-r to return control to the local screen.” But, I’m not requesting any new features.

I’m asking about a situation in which I can connect (and authenticate) to the local machine via SSH, and on this machine (although I didn’t say this), I have sudo privileges. I’m wondering if you can tell me the best currently available way to get myself out of the pickle I describe, given that I have SSH’ed in as the same user connected via NoMachine and given that I have sudo privileges.

In the past, I’ve done things like SSH’ing in and then shutting down the NoMachine server with this command:

sudo /usr/NX/bin/nxserver –stop

Then log in normally, restarting NoMachine. The trouble with this is that NoMachine seems to remember that there was a session going, but it blanks the screen again once the server starts, and I have to repeat the procedure. (I also end up losing my running X session.)

I think one time this happened, I SSH’ed in and did:

sudo apt remote NoMachine

This, of course, solved the problem. But again, I lost my running X session, and I also had to reinstall NoMachine. It’s not ideal.

More recently, I did this:

sudo /etc/NX/nxserver –history

<Get the session ID of the connected session>

sudo /etc/NX/nxserver –terminate <session id>

This worked, but again I think I lost the X session.

So: Can you suggest any other procedure that might work better?  The ideal procedure would simulate the action of disconnection from the remote end, if that is possible.

Thanks again,

Adam

I am also seeing this, and would be interested in a fix.
