The icons are themable. Change to Human icon theme and they will change. The icons are: - gnome-session-logout - gnome-session-halt - gnome-session-suspend - gnome-session-hibernate - gnome-session-reboot - gnome-session-switch - gnome-lockscreen (I am not sure about this).
I think this bug should be closed -- Themable logout dialog https://launchpad.net/bugs/40314 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
