Upgrading to Ubuntu Netbook Remix 10.04 - no title bar or window decorations
I upgraded from UNR 9.04 to 10.04 the other day, and found that the window decorations such as the title bar and close/maximize/minimize had disappeared from all windows (even in “GNOME” log-in sessions).
My particular problem seemed to be caused by saved GNOME session state. I’ve attached a suggested resolution to Launchpad bug #576696.
