    Unable to get tight VNC working

    Hi Forum,

    Im a new linux user but have been an IT tech for 15 years now. Im pretty good with Windows but Linux is a whole new world.

    Could I get some assistance with this please? Im totally stuck. I have been following guides etc and following the guides exactly. It seems that there is no single guide that gives 100% of the information so I have used bits and pieces from mulitple sources. Here is what I have done:

    Kali GNU 2019.4
    1. Login as root user
    2. apt-get install update
    3. apt-get upgrade
    4. apt-get install xfce4 xfce4-goodies gnome-icon-theme tightvncserver
    5. apt-get install tightvncserver
    6. adduser vnc
    7. apt-get install sudo
    8. gpasswd -a vnc sudo
    9. su - vnc
    10. chmod 755 /home/vnc/.vnc/xstartup
    11. chown vnc /home/vnc/.vnc/xstartup
    12. chmod 755 /root/.Xauthority
    13. chown vnc /root/.Xauthority
    14. vncserver
    15. nano .vnc/xstartup (add gnome-session & to the bottom of the file)
    16. vncserver -kill :1
    17. vncserver :1 -geometry 1280x720 -depth 24 -dpi 96 (same as desktop resolution but not sure about depth and dpi)

    When starting the VNC server as the VNC user I get this:
    Timeout in locking authority file /root/.Xauthority

    When attempting to connect with the client I get "Unable to contact setting server could not connect: permission denied"

    So I tried running vncserver as the root user. It doesn't error when starting but I just get a grey screen with a black X as the cursor.

    Any suggestions on what I am missing please? Should tightvnc run OK as root? I read somewhere else that it won't run as the root user for security reasons.

    Firstly I removed tightvnc

    Code:
    apt-get remove tightvnc
    Then I installed x11vnc

    Code:
    apt-get install x11vnc
    The defaults of x11vnc just worked right off the bat. No screwing around with the desktop environment settings or startup behaviour. It just worked immediately.

    After some more fiddling about I even managed to get it to start as a system service so I get presented with the login screen. I should have probably added to my cheat sheet how I did this but I didn't. If you really really want to know how to do this (and can't figure it out after searching for it) i'll dig out the article that I used.

    I already have x11vnc installed, Maybe if I follow the tutorial you used it might help.

    We recommend tigervnc though, that works with new NH app including KeX VNC out of the box

    I cannot connect to tigervnc though using realvnc client on windows (32bit)

    vnc server is starting fine no errors, but after connection attempt status of vncserver.service shows :

    Feb 12 23:43:54 kali dbus-daemon[1623]: [session uid=0 pid=1621] Activating service name='org.gtk.vfs.Metadata' requested by>

    Feb 12 23:44:15 kali org.gtk.vfs.Daemon[1806]: A connection to the bus can't be made

    Looks like a kernel problem (out of memory on dbus ?)... any ideas ?

    Cheers
