When it returns False the row can't be selected. Here's an example: treeview = builder.get_object("treeview3") selection = treeview.get_selection() selection.set_select_function(_select_func, ...

From there I had the same issue..when I was prompted to enter a password it would not let ...

If you have tried everything and still have the same problem check the ~/.xsession-errors log file and see if there is an error like this: init: dbus pre-start process (PID XXXX) terminated with status 2 If that's the case you may have a problem with the upstart cache. After rm -rf ~/.cache/upstart and a reboot unity started to work again.
