startx doesn't connect to internet, it just launches the graphic interface. If you want to check network connectivity try :
ping google.frX11 doesn't start because it can't find the driver for the VirtualBox video card during auto-detection. To circumvent the problem, you'll need to create a configuration file called xorg.conf to force another driver.
To automatically create one, type :
Xorg -configureThen, move the file to /etc/X11 with :
mv xorg.conf.new /etc/X11/xorg.confAt this point, running startx should start the X server with the VESA driver.
If you want to quit X11, type exit in the login window. You'll be back to the console prompt.
