I have a computer with an attached display starting a Java application via startx.

Now I want to access the application remotely via VNC. Is it possible to open a x11vnc session for one Xorg window? (Without window manager)

# x11vnc -display :1
12/11/2019 13:31:53 x11vnc version: 0.9.13 lastmod: 2011-08-10  pid: 2759
No protocol specified
12/11/2019 13:31:53 XOpenDisplay(":1") failed.
12/11/2019 13:31:53 Trying again with XAUTHLOCALHOSTNAME=localhost ...
No protocol specified

12/11/2019 13:31:53 ***************************************
12/11/2019 13:31:53 *** XOpenDisplay failed (:1)

*** x11vnc was unable to open the X DISPLAY: ":1", it cannot continue.
*** There may be "Xlib:" error messages above with details about the failure.

/bin/sh /usr/bin/startx /usr/bin/java -jar my.jar -- :1
 \_ xinit /usr/bin/java -jar my.jar -- /usr/bin/X :1 -auth /tmp/serverauth.XruRNQHDLk
      \_ /usr/lib/xorg/Xorg :1 -auth /tmp/serverauth.XruRNQHDLk
     \_ /usr/bin/java -jar my.jar

Edit: I found out, that running the startx command without my systemd service works perfectly fine with x11vnc. Now I struggle to attach the x11vnc server to my systemd startx service.

  • What user is the startx running as? Also root? – Eduardo Trápani Nov 12 '19 at 12:53
  • Yes startx is running as root. – Nortol Nov 12 '19 at 12:55
  • All the processes you can see are running as root – Nortol Nov 12 '19 at 12:55

You can add x11vnc to ~/.xinitrc or, even better, to ~/.xsession.

  • Thanks you. I edited the initial post because the problem shifted. – Nortol Nov 12 '19 at 13:49

The problem was the systemd service. I changed my service to start with the runuser command. (Both x11vnc and startx)
