I have installed Lubuntu 14.04 on my computer but i can only log into terminal (tty1) and not graphical mode. So i want to install Graphical mode via terminal i tried every possible thing to make it work.I ran command like
sudo apt-get install lubuntu-desktop
But it didn't work gave an error about broken held packages so I installed aptitude and again ran sudo aptitude install lubuntu-desktop. then I upgraded updated dist-upgraded. After rebooting, I got an error "The System running on low graphics" so I followed these steps.
Now no error of low graphics but still Lubuntu is in command line and whenever i press Alt+f7 only black screen appears.
I am not understanding at all what's happening.
