My computer for some reason is no longer booting into the GUI. It sends me straight to the command line. How do I get it to launch the GUI and how do I get it to launch the GUI by default on startup? I'm using Lucid Lynx.
I was able to get the login screen by running: sudo start lightdm
This was in Ubuntu 12.04.1 though so YMMV.
This may not serve as an answer (but I can't comment yet):
when u login on terminal type
Best luck :)
