    One of our users is experiencing strange hanging in certain applications when connecting with NoMachine.  There even seems to be some interaction with local applications if the NoMachine connection is up.

    Sorry this is vague, but it’s a very strange thing.  Is anyone else seeing this?

    EL8.10, NoMachine 8.11.3

    There even seems to be some interaction with local applications if the NoMachine connection is up.

    Do you mean that even if the application seems to hang, the user can still move the mouse and/or key press events show on the remote desktop?

    Is the display server Wayland or Xorg?
    What desktop environment is the user connecting to on the EL host?
    Is the user connecting to a free NoMachine host? Is it headless?

    This is KDE on Xorg.  It is a headless host.  Client is the free version.  One host is using the free version, another is the workstation version.

    If you attach a monitor to the server do the applications hang?

    This was caused by our attempts to automatically register the nomachine pkcs11 module via /usr/share/p11-kit/modules/nomachine.module:

    module: /usr/NX/lib/libpkcs11.so

    When not running in a nomachine environment this causes problems, at perhaps inside of one as well.

    Hi, maybe your answer is for your other topic? 🙂

    No.  Our attempt to address that issue broke firefox and other applications.

    Clear. So we will need logs when this behaviour is reproduced. Please submit from both sides, not forgetting the client sides logs as well. Please see the instructions here for those: https://kb.nomachine.com/DT09T00266. For clients side logs please refer to the section “Fourth Step: Collect Client Side Logs”. You can submit them to forum[at]nomachine[dot]com.

    If the smartcard has a UBS interface, could you try forwarding the device using the USB option instead? Does it show?

    Edit: Submit a new topic if the issue re-occurs.
