Gray screen with cross cursor in TightVNC

Question

I am trying to VNC to a Ununtu 16.04 from windows 10. I am getting a textured gray screen with cross cursor.

Below is my log file:

My xtartup file looks like:

#!/bin/sh

# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
x-window-manager &

I have searched internet thoroughly and have tried a lot of things suggested, but nothing does what I am looking for. If I comment the last two lines in the xstartup file, I get a smoother version of this gray screen with 3 check boxes on top-left corner. What I am looking for is a GUI as if I am directly using that machine.

Edit: I have checked; /etc/X11/xinit/xinitrc is installed. Following is the list of x11* packages that are on the system:

Edit 2: I checked -- file /etc/X11/xserver/SecurityPolicy is not present. I searched online. It seems a lot of others had this problem, but no solutions are there.

It means exec /etc/X11/xinit/xinitrc failed to execute. If it did, it won't go thru the next lines. Make sure /etc/X11/xinit/xinitrc exists. Kindly update your post and include all xorg-x11-* packages that are currently installed, – Tgroup

@alvits, I have updated the question. – Boatbill

You need to install xorg-x11-server-Xorg and at least 1 of the following desktop managers, gdm, kde, wdm or xorg-x11-xdm. If Ubuntu's packaging is good, it should pull all the dependencies. – Tgroup

I have exactly the same problem. None of these advices works – Portly

I have the same problem. Did someone resolved this ? – Overshine
