I am trying to get into terminal on a Xubuntu system, but when I select terminal in the menu, I get logged out and the log-in screen comes up.
The reason I am trying to do this, is that I have just installed Puppy400 frugal on the system and I need to edit /boot/grub/menu.lst
If I try to edit menu.lst using a gui editor, I cannot save the file as I don't have superuser access so I need to go to terminal and sudo.
Shift/Ctrl/n doesn't help. It puts me to a cli prompt, asks for a user name and password and hangs.
