I've found that the following works on Ubuntu 9.10 Karmic while using wireless and WPA2 on my laptop:
After hours of beating my head against the wall trying to figure out how to get rid of those time-consuming CIFS VFS errors during shutdown, I cobbled together this (ugly) fix.
I take no credit for this script. I found it here. I simply put two and two together, as I guessed this script may execute before Network Manager is killed. I just plugged in the umountnfs.sh portion.
- Save the script somewhere safe. I saved it in ~/Scripts, and gave it root-only permissions.
- sudo chmod +x /path/to/script/scriptname
- Add the script to your Start-up Applications. (System > Preferences > Startup Applications)
Code:
#!/usr/bin/env python
#Author: Seamus Phelan
#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). This is different to placing scipts
#in /etc/rc#.d/ as the script will be run before gnome exits.
#If the custom script/command fails with a non-zero return code, a
#popup dialog box will appear offering the chance to cancel logout
#
#Usage: 1 - change the command in the 'subprocess.call' in
# function 'session_save_yourself' below to be what ever
# you want to run at logout.
# 2 - Run this program at every gnome login (add via menu System
# -> Preferences -> Session)

- Run in terminal:
- Add the following to the bottom of the file:
Code:
%admin ALL=NOPASSWD: /etc/init.d/umountnfs.sh
- Press Ctrl-X to exit, press Y to save changes, and hit [Enter] to write the file.
I hope this helps! I'm a linux noob, so apologies if my guide wasn't perfect.
