Hello, I am working on a fairly well-known ongoing problem where you have a slow logoff if connected wirelessly to a Samba share. You get the message 'CIFS VFS: No response ...' and it takes about 2 minutes for the laptop to shutdown. Apparently it happens because Network Manager closes down before the CIFS mounts are unmounted.
It will probably be some time before this gets fixed at the root cause but there is a good work-around for Gnome. It entails running a process in the Gnome session that waits for the 'save-yourself' event (see below). Is there a similar closing-down event that can be hooked into with an XFCE session ? Would anyone be able to supply the few lines of code required in main() below ? I could then test and, if successful, post the solution back into the Ubuntu forums article below. #!/usr/bin/env python #Author: Seamus Phelan # http://ubuntuforums.org/showthread.php?p=8451352#post8451352 #This program runs a custom command/script just before gnome shuts #down. This is done the same way that gedit does it (listening for #the 'save-yourself' event).
