Setup a virtual screen for connect from VNC viewer (example VNC VIwer Android)

enable-remote.sh

#!/bin/bash

WIDTH=1280
HEIGHT=800
x11_cmd=x11vnc

if [[ ! -z $(pgrep ${x11_cmd}) ]]; then
	pkill ${x11_cmd}
fi

MODE=$(gtf ${WIDTH} ${HEIGHT} 60| egrep -v '#' |  awk '{first = $1; $1 = ""; print $0, first; }')
MODE_NAME=$(echo ${MODE} | awk '{ print $1}')

OFFSET=$(xrandr | grep primary | awk '{ print $4}' | sed 's/\([0-9]*\)\(.*\)/\1/')
PRIMARY=$(xrandr | grep primary | awk '{print $1}')
VIRTUAL=VIRTUAL1

xrandr --newmode ${MODE} 2> /dev/null
xrandr --addmode ${VIRTUAL} ${MODE_NAME} 2> /dev/null
xrandr --output ${VIRTUAL} --right-of ${PRIMARY}

LOG=/var/log/x11vnc.log

if [[ ! -f "${LOG}" ]]; then
	sudo touch ${LOG}
	sudo chown ${USER}. ${LOG}
fi

x11vnc -usepw -noxdamage -bg -forever -display $DISPLAY -clip "${WIDTH}x${HEIGHT}+${OFFSET}+0" -o ${LOG}
xset r

Thanks, works great!

How I can create the Virtual1 Display?

@Sergi030 i had the same issue, got it back after creating
/usr/share/X11/xorg.conf.d/20-intel.conf
Section "Device" Driver "Intel" Identifier "Intel" EndSection

I just found out you don't need vnc server, You can just use software like deskscreen and share ur virtual monitor lol
