Annoyances
Ubuntu 9.10+10.4 shows the list of existing users on the login screen. You can disable this feature as follows: Open sudo -u gdm dbus-launch gconf-editor and then select apps -> gdm -> simple-greeter and toggle disable_user_list to True. Finally execute Close Window.
Ubuntu 10.4 shows the close, maximize, minimize buttons on the left side of the title bar. Switch back to the right side with gconf-editor: Choose apps -> metacity -> general and change the variable button_layout from "close,minimize,maximize:" to "menu:minimize,maximize,close".
