I have been using ubuntu for quite sometime now and haven't ever faced this situation. All my icons are missing including the terminal. ctrl+Alt+T does not bring up the terminal, right clicking does not show any dropdown either. Most of the answers that I found were wrt to unity and cases where terminal was present. I am using ubuntu 16.04
Any solutions as to how this can be fixed are most welcomed.
