Neither the desktop icons nor the launcher display after I log in.
First, try this:
sudo rm -fr ~/.cache/compizconfig-1
sudo rm -fr ~/.compiz
sudo rm -fr ~/.Xauthority
sudo rm -fr ~/.config/autostart
sudo reboot
If the above doesn’t work, try this:
sudo apt-get update
sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install unity
sudo reboot
