[Toshiba Satellite M645] Keyboard backlight does not work

[Matt White]

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.]

[Matt White (mattw922)]

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
Fabio

[SkekTek (skektek)]

I have the A665D-S5175 and the results are the same with 11.04 April 4th build:
ACPI on: no keyboard backlight.
ACPI off: keyboard backlight works perfectly.

[satet (order-regis)]

I just tried the daily (26 April 2011) version of Ubuntu 11.04. The keyboard backlight problem has not been solved for my Toshiba
A665D-S6059. With acpi=ON the lights do not work, with acpi=OFF the lights do. This has been a problem for me since 10.10.

[satet (order-regis)]

I downloaded and tried the live disk for the final version of Ubuntu 11.04. The keyboard backlight problem has not been fixed.

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.

[Aaron Gerber (agerber85)]

Bought my Satellite last month, installed Oneiric a couple weeks ago, and I don't believe I've seen the keyboard backlight work in Ubuntu once.

[Tony (tonyget)]

I have dual boot and I found out that when I boot with Windows, the next time I boot Ubuntu (11.04), the lights work, but when I boot Windows again, they stop working. I don't know why.

I fail to see how this is how priority bug it has to affect a lot of machines and with the future in pads and tablets I would think this warrants resolution https://help.ubuntu.com/community/MacBookPro6-2/Lucid#Keyboard gets warm but not nailed

[Matt White (mattw922)]

I think most of us have just learned to live with it, hence the lack of complaining. But it's still annoying when I try to code in the dark. Why don't we just get it fixed?

[penalvch (penalvch)]

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?
