I confirm this bug as well. You can put text into it by clicking with the middle-mouse-button. When selected it seems like the focus is overridden by the currently active window, so this might rather be a bug in compiz.
When opening the Gnome-Menu, the focus in the deskbar becomes visible, but you still cannot type and upon closing the menu, the focus disappears again. -- Deskbar is unselectable when using xserver-xgl https://launchpad.net/bugs/35475 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
