Answer 2

I'm using the following Bash function:

# Configure virtual display and wine.
# Usage: set_display
set_display() {
  export DISPLAY=${DISPLAY:-:0} # Select screen 0 by default.
  xdpyinfo &>/dev/null && return
  if command -v x11vnc &>/dev/null; then
    ! pgrep -a x11vnc && x11vnc -bg -forever -nopw -quiet -display WAIT$DISPLAY &
  fi
  ! pgrep -a Xvfb && Xvfb $DISPLAY -screen 0 1024x768x16 &
  sleep 1
  if command -v fluxbox &>/dev/null; then
    ! pgrep -a fluxbox && fluxbox 2>/dev/null &
  fi
  echo "IP: $(hostname -I) ($(hostname))"
}

Then source the file and call set_display. Consider configuring the password via -usepw.

I'm using it in the following Docker project (check .funcs.cmds.inc.sh).
