I have downloaded this image https://bitnami.com/stack/edx/virtual-machine and installed it in virtual box
Then I executed the following
sudo apt-get update
sudo apt-get install ubuntu-desktop
set display=:0
ubuntu-drivers devices | grep recommended
sudo apt-get install (recommended driver file)
sudo apt-get update
sudo apt-get upgrade
sudo reboot
startx
However the desktop is empty, what can I do know? how do I open a browser? network settings?
