X11 Forwarding for Desktop over SSH
Type the command below, which will activate xinit in virtual terminal 8. Note that you will be automatically switched to virtual terminal 8. You can switch back to the original virtual terminal 7 by pressing Ctrl+Alt+F7.
# xinit -- :1 &
After switching to virtual terminal 8, execute the following command to launch the RPi desktop remotely. Type pi user password when asked (see picture below).
# DISPLAY=:1 ssh -X pi@192.168.2.5 lxsession
You will bring to your new virtual terminal 8 the remote RPi desktop, as well as a small terminal launched from your active virtual terminal 7 (see picture below).
Remember, do not close that terminal. Otherwise, your RPi desktop will close immediately.
You can move between first and second virtual terminals by pressing Ctrl+Alt+F7 or Ctrl+Alt+F8.
