For learning purposes, I'm trying to start my GUI (unity) on Ubuntu 12.04 from the command line.
quiet splash in
text and I successfully booted into the command line. I was able to start X11 and play around with some lightweight window managers like icewm-lite. Now I want to start the full unity desktop that's default with ubuntu 12.04, so I type
unity in the command line and I get
WARNING: no DISPLAY variable set, setting it to :0 compiz (core) - Fatal: Couldn't open display :0 unity-panel-service: no process found
and unity doesn't start. What am I doing wrong?
