Well, I am definitely a newbe, so I am sure someone out there will be laughing their pants off over the trouble I brought myself in.
I was trying to mount some network drives, I found this post:
and thought I was home free. I tried to do what it said, but apparently messed things up big time in the process. Now my Ubuntu partition starts up with the command line and I cant get into the GUI and I can't edit fstab back to what it originally was (I can edit the file using Editor, but can't save it (even after starting Editor with sudo). If I can start up the GUI I can probably find my way through the mess I have created. But why oh why does it suddenly start up with only the command line?
Hopefully someone can guide me on my way.
