I was trying to learn more about xorg configuration and came through an exercise that should be run at run level 3. So, I wrote init 3 in the command line then the x server stopped and the system was trying to enter run level 3 but then it hangs and nothing happens. At that time I was connected to the system via putty and wrote the command init 5 and the x server started again normally. I tried init 3 again and had the same thing.
