Use ctrl + alt + F1 to switch to terminal, 2. login. 3. run sudo service lightdm *stop* , lightdm and *xserver* should be stopped now (check with ctrl + alt + F7 , which is your current *xorg* session, it should not show any desktop now) 4. do your things. 5. run sudo service lightdm start to start lightdm and *xorg* again.
