<EDIT> Starting again

The information you want should be here:

http://www.thinkwiki.org/wiki/How_to_setup_Bluetooth

and mentions the Fn-F5 button too.

If Bluetooth is disabled and you have Ibm-acpi running you could enable/disable bluetooth by entering:
#

Code: Select all

echo enable > /proc/acpi/ibm/bluetooth

or
#

Code: Select all

echo disable > /proc/acpi/ibm/bluetooth

You should also be able to toggle bluetooth with Fn+F5 keys.

------------------------
Can you try:

Code: Select all

echo enable > /proc/acpi/ibm/bluetooth

Also the critical phrase there is

If IBM-acpi is running. If it's not it may explain why you're also getting the higher temps as in your other post.

I'll get back with checking how to make sure IBM-acpi is running

Good old Lightweight to the rescue

In one of his other posts he lists the commands to show the state of ibm-acpi.

So could you post back the outputs of:

Code: Select all

lsmod |egrep "acpi|ibm|think"

and

Code: Select all

ls /proc/acpi

Thanks Lightweight for that!

Posted: **Tue Sep 30, 2008 7:49 pm**

Code: Select all

echo enable > /proc/acpi/ibm/bluetooth 
echo disable > /proc/acpi/ibm/bluetooth

thanks , those 2 commands works to open and close bluetooth .

i wonder if lightweight know code change Fn+F5 to open wireless
then he should know how to turn it back to open bluetooth !!!

thx for help Nick

Good that the commands switch bluetooth on & off.

I'm sure I found a post last night about enabling the Fn-F5 button & I'll have a look around tonight for the post. I'm fairly sure it was in Ubuntu forums if you want to have a look yourself - do an advanced search under 'bluetooth'.

In the meantime, you may be able to create two Desktop launchers - one to switch bt on, and the other to turn it off:

Accessing Desktop launcher:

Desktop - right mouse click > Create launcher.
New launcher window opens

-------------------------------------------------
Launcher for turning bluetooth on:

Type: select 'Application in Terminal'
Name: Bluetooth On (call this anything you want)
Command: copy the code below into this box:

Code: Select all

echo enable > /proc/acpi/ibm/bluetooth

Comment: leave blank.

At the top left handside of the window there's a spring like symbol. Click on this and select a suitable icon for your launcher (not necessary but makes it look better!).

-------------------------------------------------

Launcher for turning bluetooth off:

Type: select 'Application in Terminal'
Name: Bluetooth Off (call this anything you want)
Command: copy the code below into this box:

Code: Select all

echo disable > /proc/acpi/ibm/bluetooth

Comment: leave blank.

As above for a launcher icon.

---------------------------------------

When you click either icon there'll be a brief flash on the screen as the terminal opens to run the command, and hopefully bluetooth will be switched on or off.

Assuming this works, you only have a single mouse click rather than two fingers to operate the keyboard!

Type: select 'Application in Terminal'

Code:

hello , i was doing this way on windows

and i tried it on ubuntu as u said , but dont know why it don work when i press on shortcut !!!?

(even if you get an error, post the output. Basically post anything your terminal spits out during the steps below -- errors are useful.)

What happens if you just call the target of Fn+F5 directly?

Code: Select all

sudo /etc/acpi/ibm-wireless.sh

If bluetooth does turn on, there's some problem with acpi calling the script, or with the script itself.
- do this, press Fn+F5, and paste the output. We're looking to see if acpid calls an error before, after, or while it tries to talk to the hardware abstraction layer.

Code: Select all

sudo tail -f /var/log/messages

(in a second terminal)

Code: Select all

sudo tail -f /var/log/acpid

- and this, to make sure all users can call the script.

Code: Select all

ls -l /etc/acpi/ibm-wireless.sh

- and make sure acpi has the right keymap to call the right script

Code: Select all

cat /etc/acpi/events/ibm-wireless

If bluetooth does not turn on, it sounds like the script was not backed up or restored correctly. It should look like this (notice that it only sanity checks if bluetooth is on, then echos enable or disable into /proc/acpi as poshgeordie instructed you to before. Linux is cool

)

Code: Select all

#!/bin/sh

test -f /usr/share/acpi-support/power-funcs || exit 0

# Find and toggle wireless of bluetooth devices on ThinkPads

. /usr/share/acpi-support/state-funcs

BLUETOOTH=/proc/acpi/ibm/bluetooth

if [ -r $BLUETOOTH ]; then
    grep -q disabled $BLUETOOTH
    bluetooth_state=$?
fi

# Note that this always alters the state of the wireless!
toggleAllWirelessStates;

# Sequence is Both on, Bluetooth only, Wireless only, Both off
if ! isAnyWirelessPoweredOn; then
    # Wireless was turned off
    if [ -w $BLUETOOTH ]; then
        if [ "$bluetooth_state" = 0 ]; then
            echo enable > $BLUETOOTH;
        else
            echo disable > $BLUETOOTH
        fi
    fi
fi

'case anyone else wants to make Fn+F5 toggle wireless, its the same concept except you're doing an ifconfig up and down for the wireless interface. Battery-minded folk can save some time if they load and unload their wireless card's modules as well. You can either edit the ibm-wireless event (to call your new script) or the target (/etc/acpi/ibm-wireless.sh). Make sure the target script is executable by the acpi daemon.

Anyway, HTH.
