Howto: toshset, bluetooth etc on 8.10 Intrepid Ibex

[adpsimpson]

In certain Toshiba laptops the bluetooth will only work using the toshset utitlity. In previous versions of ubuntu, this worked flawlessly. Expect it be be fixed soon in 8.10, but in the mean time it's worth having this here.

There are 2 issues to solve.
1) 8.10 kernels are compiled without the toshiba_acpi module, which is required by toshset.
2) Versions of toshiba_acpi in recent kernels do not work with toshset

The solution is to patch and compile the toshiba_acpi kernel module and manually install it. This is easier, and should be more compatable, than compiling the whole kernel.

I am far from an expert, so the steps below could probably be done better - please do add further info.

Here are the steps I took:

Install required packages

sudo apt-get install build-essential linux-source libncurses5-dev kernel-package

Copy and extract the kernel sources to a working directory (check your version number)

cd ~
mkdir src
cp /usr/src/linux-source-2.6.27.tar.bz2 src
cd src
tar xvjf linux-source-2.6.27.tar.bz2

Download the patch from here that most closely matches your kernel version. the 2.6.26 patch works on kernel 2.6.27 currently used in ubuntu 8.10.

wget http://memebeam.org/free-software/toshiba_acpi/toshiba_acpi-dev_toshiba_test5-linux_2.6.26.patch

Apply the patch - the first command checks it will all work. Only continue if it gives no errors.

patch -p0 < toshiba_acpi-dev_toshiba_test5-linux_2.6.26.patch --dry-run
patch -p0 < toshiba_acpi-dev_toshiba_test5-linux_2.6.26.patch

Create a makefile:

nano Makefile

Copy the following contents in, then exit with Ctrl+X, type 'y' to save, and take the default location:

obj-m += toshiba_acpi.o

all:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

clean:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

Build the kernel module:

make

There should now be a whole lot of files in that folder. The important one is called toshiba_acpi.ko

To install the module by hand, you need to copy it to the correct directory and modify one file which tells the kernel what dependencies the module has.

sudo cp toshiba_acpi.ko /lib/modules/`uname -r`/kernel/drivers/acpi/
cd /lib/modules/`uname -r`

Using the following command should add the required line to the end of the file, but for some reason even as sudo and having modified file and directory permissions, I got a permission denied error:

echo "/lib/modules/`uname -r`/kernel/drivers/acpi/toshiba_acpi.ko:" >> modules.dep

It works with nano though:

echo "/lib/modules/`uname -r`/kernel/drivers/acpi/toshiba_acpi.ko:"

Copy this output, then:

sudo nano modules.dep

press page-down to end of file, then paste in the copied output. Save and exit (Ctrl-X, 'y', Enter)

That should be it done. You can then load the module using:

sudo modprobe toshiba_acpi

Bluetooth can be turned on and off using the commands:

sudo toshset -bluetooth on
sudo toshset -bluetooth off

Further info from toshset:

sudo toshset -a

Done!

As always, I'm a beginner in this game, but if this helps a few others until the official patch is released then it's worth it.

Thank you so much for this post! This is exactly what I've been looking for. However, when I try to execute the patch (with options --dry-run) I get the following error:

<computer>:~/src$ patch -p0 < toshiba_acpi-dev_toshiba_test5-linux_2.6.26.patch --dry-run
can't find file to patch at input line 3
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|--- toshiba_acpi.c.orig 2008-08-30 22:12:50.000000000 -0700
|+++ toshiba_acpi.c 2008-08-31 12:03:07.000000000 -0700
--------------------------
File to patch:

Any idea why this might be happening? I verified that toshiba_acpi.c does exist, it's in /drivers/acpi/toshiba_acpi.c. How do I work through this?

Thanks!

[rubentm]

WOOOOOW!!!! THX. U are the best!!
The only thing that needs to add is, before aplying the patch:

cp toshiba_acpi-dev_toshiba_test5-linux_2.6.26.patch linux-source-2.6.27/drivers/acpi
cd linux-source-2.6.27/drivers/acpi

U ROCKS!!!

[raztus]

Thanks rubentm for the added step! That solved the error from my first post.

adpsimpson: the only part of your steps that confused me was the line "Copy this output, then: sudo nano modules.dep". I thought you were telling me to copy sudo nano modules.dep. A better way to word it would be "copy the above code, then run the following: sudo nano modules.dep".

Unfortunately for me, it looks like I might be out of luck on a Toshiba Satellite A305. My bios is v 1.50 InsydeH20. Turns out this probably isn't suppoted by toshiba_acpi. From http://memebeam.org/toys/ToshibaAcpiDriver:

Another important note: This driver does not work on all Toshiba laptops, particularly those models which seem to have a BIOS or other firmware which was not developed by Toshiba itself. New reverse engineering work will have to be done on these machines, or Toshiba will have to disclose the necessary details. (For support of machines with Phoenx BIOS, try the [Omnibook driver].) The error you will see in this case is:

$ modprobe toshiba_acpi
FATAL: Error inserting toshiba_acpi
(.../kernel/drivers/acpi/toshiba_acpi.ko): No such device

This is the exact error I got. I guess I'll try the Omnibook driver! Thanks for your help.

Hello,

thanks for this detailed procedure !
I've one problem when i execute this command :

sudo modprobe toshiba_acpi

The result is :

FATAL: Error inserting toshiba_acpi (/lib/modules/2.6.27-9-generic/kernel/drivers/acpi/toshiba_acpi.ko): Unknown symbol in module, or unknown parameter (see dmesg)

And dmesg :

[ 2334.701916] toshiba_acpi: Unknown parameter `hotkeys_over_acpi'

Can i've help please ?

[Paresh]

I get this error also on my Toshiba Tecra A9


'dmesg | grep toshiba' gives this

[28067.064484] toshiba_acpi: Unknown parameter `hotkeys_over_acpi'
[28110.661291] toshiba_acpi: Unknown parameter `hotkeys_over_acpi'
[28138.558902] toshiba_acpi: Unknown parameter `iba_acpi'
[28169.318486] toshiba_acpi: Unknown parameter `hotkeys_over_acpi'

Any help would be appreciated

[Paresh]

Well, I fixed my error by removing the line

options toshiba_acpi hotkeys_over_acpi=1

from the 'toshiba_acpi.modprobe' file and it worked for me.

Not sure what this line does, but bluetooth is now working.

Only issue now is that I have to do

sudo toshset -bluetooth on

after each reboot or resume from suspend.

[anjames]

Seems to work well enough, including of course the fixes added by rubentm and Paresh.

Now I'm roughing it out with toshset and xorg.conf trying to get my second monitor working...
toshset -v -video both
xorg.conf ...?

To the intergoogle.

Hello, i have a problem with the patch:

any ideas as to what may be the problem? I'm running on 8.10 intrepid fresh installed.

[trundlenut]

I have had exactly the same problem after reinstalling and updating intrepid. It worked OK a week or so ago so I am assuming that a recent update has done something to stop it. I have no idea what though.
