How do I open gnome-panel?


I'm trying to use gnome-panel. I run the command "gnome-panel" from the command line (gnome terminal) in my user account and get a pop-up box that says: "I've detected a panel already running and will now exit." When I do the same from root account, I get, "cannot open display"

Not sure what's going on here.

gnome-panel will start the menu bar and system tray at the top of the screen, and the task-bar and desktop switcher at the bottom of the screen.

You can only have one instance running at a time - if the Gnome panels are already visible, then you can't start another instance.

By default, only the user that started the X-Windows environment can use that display. Since your user started X, then root can't display windows on your display. If you run the command "xhost +" as the user that "owns" the display, then you can start other GUI apps using other user accounts such as root.

I hope this helps

Thanks. That makes perfect sense.

If you were trying to "open" the panel to add it, just right click on an empty portion of the panel you want and a menu of applet add-ons comes up. Assuming you're starting from a default Ubuntu install, there are a top and bottom panel. You may add to them independently. They can also be moved to the sides and the panel width and appearance can be modified with Properties.
