Yes, NX successfully connects to server now that X is properly installed.  Perhaps there’s an issue remaining w.r.t. the claim that NX will ‘create a Virtual display on demand’ and doesn’t.  I suspect the bad X installation is the root of that problem too.

[iceback]

The issue has been resolved by fixing the xdm initialization.  I believe that is a remnant issue in what NX is doing in absence of a GUI – claiming it will start an virtual session, then failing to do so – but that’s for another day.

The heart of the issue is a fault in ‘prefdm’ script:  it does an rpm query for packages which supply a graphical interface, then iterates over the results.   The configuration of the server in question had at some point in the recent past (last OS update?) lost it’s X packages and the query return “no packages found for graphical interface” but the prefdm script never recognized the error and tried to process each of those words as a possible display manager!  And did so repeatedly.

Re-installing the 500+ packages involved in X did the trick.

This machine has a KVM attached so it should not be (and in the past wasn’t) headless. Currently x is not starting and am looking in to that as well.

Please confirm.

Attaching logs generated with debug level 7. It seems to be in a tight loop.

As I said u0886896 was a member of the team but has moved on. BTW, that Id had ‘technical difficulties’ and he was issued a new account name “raja”.

I can/have reproduce the problem over several nxserver –restart calls and will do so again (barring a miracle). Do you want the .xsession from the client or the server?

[iceback]

Thanks for that clarification.

[iceback]

I will try another install, but it won’t be this week.  Just back from vacation and am far behind

Relevant contents of the server.cfg file suggest post #11940 is not applicable

# Set the interaction level for the session connected to the physical

successfully ran

• setxkbmap -option “” -option “ctrl:swapcaps” -option “terminate:ctrl_alt_bksp“

Yes, that used to work but now, from an ubuntu client, it has no effect.  I disconnected from my session, ran that on my desktop, restarted nxserver, reconnected and no change

 

[iceback]

Yes, both server and client are running linux.  Centos 6.7 on the server, Ubuntu-14.04 on the client

 

[iceback]

The client would have been 5.50~ and the server was 4.6.4

[iceback]

Well yes, the graphics come from the nx-server end of course.  From my end it’s all keyboard and mouse.  Still suspect a client side delay/buffering as part of the problem.

[iceback]

Is there any input buffering?  As in ‘wait-this-long’ for more keyboard input before sending to server? And if so is it configurable?
