[Toshiba Satellite M645] Keyboard backlight does not work

Bug Description

Disabling ACPI causes the keyboard backlight to work perfectly. However, this has the unfortunate side effect of disabling monitor brightness control and suspend ability (and likely other things). Is there a way we can just disable ACPI for the keyboard alone?

Hi Matt,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 683133

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

    [This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

Jeremy,

It is indeed still an issue. Unfortunately I can't check with the latest dev version of Ubuntu as this is a work machine. Sorry!

Hello
Can someone test a live session of the newest build of Natty downloading from:
http://cdimage.ubuntu.com/daily-live/current/
to see if it is reproducible in the latest kernel?
Thanks

Last week I made a major update last week and the lights started to work out of the blue, but then I made a minor update a couple of days ago and they stopped working again. I don't know what exactly were the updates about (I just say yes to the update manager), so I don't know if this would be of any help.

Matt White, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 10, 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so:

+ Could you please specify the full computer model noted on the computer's sticker?
+ Could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.8-rc1

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

Hi, I'm in Ubuntu 12.10 64 bit with a Toshiba Qosmio X770-11Z and the keyboard backlight doesn't work either.
I tried almost all kernel from 3.2.0 until 3.8.8 and didn't solved the problem.
When I had ubuntu 12.04, I had the same error.
Also, toshset doesn't start, it says "required kernel toshiba support not enabled." and when I patch the kernel to make it work, it says "This PC does not have a Toshiba BIOS".
The only way to make it work for a few days is to have windows OS and hard reset it, but I can't still manage the backlight, only in BIOS and, as I said, after a few days, stopped working again.
Anything I can do to help?
