E2B-2497 How do i change the desktop Enviroment

You'll need to change the startup script. This is currently hardcoded in Python and JS SDK but we will make it possible to configure it separately. Here's an example start script for XFCE:

#!/bin/bash

# Set display
export DISPLAY=${DISPLAY:-:0}

# Start Xvfb if not running
if ! pgrep -x "Xvfb" > /dev/null; then
    Xvfb $DISPLAY -ac -screen 0 1024x768x24 -nolisten tcp &
    sleep 2
fi

# Start XFCE session if not running
if ! pgrep -x "xfce4-session" > /dev/null; then
    startxfce4 &
    sleep 5
fi

# Start VNC server
x11vnc -bg -display $DISPLAY -forever -wait 50 -shared -rfbport 5900 -nopw \
    -noxdamage -noxfixes -nowf -noscr -ping 1 -repeat -speeds lan &
sleep 2

# Start noVNC server
cd /opt/noVNC/utils && ./novnc_proxy --vnc localhost:5900 --listen 6080 --web /opt/noVNC --heartbeat 30 &
sleep 2
