    The issue: Anytime I type anything in my remote desktop, I get letters that do not correspond to what I typed.

    Ex: The key ‘Enter’ becomes a backspace, ‘e’ becomes a ‘9’.

    It’s not just on terminal; it’s anytime I need to type. If I login to the remote server using just SSH (no NX involved), everything works fine.

    INFORMATION:

    NoMachine Product: NoMachine

    Version: 7.41

    Platform: client (Windows 10), remote: Ubuntu 16.04

    Virtual Display (I think)

    Using Lightdm on remote

    Hello, xev reports correct events and keymap looks OK as well.

    For example, qwerty produces events keypress/keyrelease for Q W E R T Y. I can’t see the E becoming 9.
    Enter and Backspace are in the expected place in the keymap.

    Did you run terminal and Xev in the remote session?

    I’m an idiot. I just realized that I couldn’t have run in the remote session because I can’t type anything in the remote session. Even if I copy and paste text into the remote terminal, I can’t figure out which button corresponds to the “Enter” button.

    So I finally figured out to run: xev -event keyboard. I typed ‘qwerty’

    New Question: How should I go about debugging this?

    Background info: this is my first time using NoMachine. It’s not like I had a working version and some update ruined my settings, etc. I’m using defaults. I checked on the keyboard settings, and it says I’m using system defaults. And when I uncheck the system defaults. I unclicked that and restarted the nxserver, but nothing changed.

    Xvnc has such a keymap. Is it possible you are running Xvnc in place of Xorg?

    This is probably what is going on. I killed vncserver (which I forgot I was running). Now, the problem is that I can’t log in.

    After stopping vncserver, and restarting nxserver, I get warning: “Cannot find X servers running on this machine.” Now, when I try to login from the client, a window pops up for about half-a-second, then immediately crashes. That’s all that happens.

    To try and get around this, I tried starting lightdm (on Ubuntu 16.04) but I can’t login. What happens is that I when I try to login, I get a “system program problem detected” popup, then I get a screen with nothing but the background (can’t interact with the desktop when it is like this), and then, after a 3-4 seconds, a new login screen is presented.

    It is likely a crash in lightdm or in the desktop environment (that is the compiz-based Unity Desktop in Ubuntu 16.04).

    If you turn lightdm off, NoMachine will present an option asking you if you want to launch a virtual display server. You’ll get an X11 session although no X server is running on the physical display.
