Ubuntu 12.04 graphical interface is gone

Question

I was trying to set up my build environment for beagleboneblack.I was following standard instructions from this site

    https://source.android.com/source/initializing.html

I was installing required packages one by one. Now after reboot, GUI is gone. It is giving a message with some options that I can't select through keyboard or mouse. Doing a escape takes me to a CLI. I tried this

 sudo services lightdm start

and

 sudo startx

but nothing happens.I remember while installing this one

  libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386

or this one

  libgl1-mesa-dev g++-multilib mingw32 tofrodos

It was removing x server things then again setting up. What can I do now? P.S. Also while installing libgl1-mesa-glx, it said something like this

  The following packages have unmet dependencies:
  libgl1-mesa-glx:i386 : Depends: libglapi-mesa:i386 (= 8.0.4-0ubuntu0.4)
  Recommends: libgl1-mesa-dri:i386 (>= 7.2)

So I did this

 sudo apt-get install libgl1-mesa-dri

yes. I reinstalled nvidia driver. Now I can't log in. After giving my password a blank screen comes and then again same login screen. — Mlo Bootloader, Aug 09 '15 at 12:36

I did some things, but in the end I installed new root partition. This is the problem with linux distros. You have to first learn various types of bug fixes before indulging in what you really intended to do. — Mlo Bootloader, Aug 09 '15 at 12:40
yes, installing root partition made me to install every package again but everything is ok for now. — Mlo Bootloader, Aug 09 '15 at 12:45
