So I booted my computer up this morning, logged in, and found that both the top and the bottom panels were gone. My desktop background is still there, but the panels aren't. When I do open a window and minimize it, it goes to nowhere. I have read a number of people with similar problems, but the solution is always "right click on the panel and add the window list." My problem is that I don't have a panel to right click on.I have Ubuntu 10.04(gnome desktop).
Any idea what happened or how to fix it?
