Ubuntu Fixed Computer Shutdown Problem

WOOT! Finally got it working after 1 whole night.

I simply edited this file:

/etc/init.d/alsa-utils

and added the lines:

ifconfig wlan0 down
ifconfig eth0 down

after "stop)" in the file (around line 353), so it looks like this:


stop)
ifconfig wlan0 down
ifconfig eth0 down
EXITSTATUS=0

:D

ok. better method which doesn't touch the sound part.

Details:

1. Open a terminal and become super-user (yeah, this is a bad security practice, but I'm too lazy to type sudo before everything).

Code:

su

2. Navigate to the init.d directory.

Code:

cd /etc/init.d

3. Touch and edit your new wireless shutdown script. I use "vi," but feel free to use "gedit" if you like.

Code:

vi killwlan

4. Add line(s) that "modprobe -r" your wireless driver module(s). In MY case, I remove "iwlagn" modules. In YOUR case, you'll need to find out the module names being used by your wireless device.

Code:

modprobe -r iwlagn

5. Save the script and exit the text editor.

Code:

[ESC] :wq [ENTER]

6. Navigate to the rc0.d directory.

Code:

cd /etc/rc0.d

7. Create a link to your killwlan script.

Code:

ln -sT /etc/init.d/killwlan S16killwlan

8. Navigate to the rc6.d directory.

Code:

cd /etc/rc6.d

9. Create a link to your killwlan script.

Code:

ln -sT /etc/init.d/killwlan S16killwlan

10. Now try to shutdown or restart.

Code:

init 6

File permission if needed:

Code:

cd /etc/init.d/
sudo chmod 755 killwlan
