Xlib: extension "XInputExtension" missing on display ":1" Atom Ubuntu

Question

I have an Amazon EC2 instance that runs Ubuntu 16.04 server. I installed atom and for some reason I am not able to start Atom. Everytime I start atom with the command line I see the following

Xlib:  extension "XInputExtension" missing on display ":1".

I used vnc to setup ubuntu desktop and I am using vncviewer to access the desktop and start atom.

I am not sure what I am doing wrong. My vncconfig file looks like this

#!/bin/sh

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

gnome-session &
gnome-panel &
gnome-settings-daemon &
metacity &
nautilus &
gnome-terminal &
[ -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 &

This is good in general if you use headless VM;

cd /usr/lib/x86_64-linux-gnu/
cp libxcb.so.1 libxcb.so.1.bak
sudo sed -i 's/BIG-REQUESTS/_IG-REQUESTS/' libxcb.so.1

It will fix all apps with same error

Reason:

Quoting from this link https://github.com/atom/atom/issues/4360#issuecomment-189942757 :

I was seeing the same error message and debugged it down to an X extension "BIG-REQUESTS". You can use xtrace to trace all the X traffic and I saw an 8MB message before it crashed. I first disabled all extensions with (xtrace -e ) and that worked. My final hack was to copy libxcb.so.1 into /usr/share/atom, open up in editor, and change 'BIG-REQUESTS' to '_IG-REQUESTS'. I figure when the client library asks if this extension is supported it will reply no and no more big messages. hope this helps

I still get the error in command prompt but I am able to start atom

Thanks to this guy https://www.zhukun.net/archives/8070

This is what I did

sudo cp /usr/lib/x86_64-linux-gnu/libxcb.so.1 /opt/atom/

sudo sed -i 's/BIG-REQUESTS/_IG-REQUESTS/' libxcb.so.1

and then

cd /opt/atom
./atom

The output of this being

Xlib:  extension "XInputExtension" missing on display ":1".
Xlib:  extension "XInputExtension" missing on display ":1".
Xlib:  extension "XInputExtension" missing on display ":1".
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell

But Atom did start as expected!! This is what I wanted.
