That thread looks like it applies but I can't open menu.lst as the thread suggests because OpenOffice denies me access. Maybe, as chipbennett says, I need Root access. I'm logged in as administrator. Do you know how to gain Root access?
Are you using GNOME or KDE?
I know that, in KDE (Kubuntu, at least), using either Dolphin or Konqueror (file explorers), I can right-click on a file or folder, and the context menu will have an "open as root" or "edit as root" option. I am unsure of Nautilus has the same functionality.
Two options:
1) Open your file explorer, navigate to / (root directory), right click on /etc, and select "open as root". If the option is available, a new instance of the explorer will open, prompt you for your password, and then display the contents of /etc with root access.
2) Use the command line to open a root-access instance of your text editor. Open a command prompt, and type "gksudo gedit" (works in Ubuntu) to open gedit with root access. I think,
based on this thread, the command in OpenSUSE would be "gnomesu gedit" to open gedit with root access (or if that doesn't work, try "kdesu nautilus" to open a root-access instance of Nautilus).
I'm not sure I can be much more help than that. I really don't know my way around non-Debian based distros.
