This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1063804

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.6 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. Please only remove that one tag and leave the other tags. 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.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

apport information

[Leonard Peris (leonard+peris)]

I am using the same machine, and I too face the same issue.

I installed the Mainline Kernel as per @jsalibury's request in comment #2. The issue remains, using the Fn+F9 keys to decrease brightness and Fn+F10 to increase brightness has no result.

Running apport against this bug fails as I am running the Mainline Kernel.
Please advise if I should modify the tags.

[penalvch (penalvch)]

Leonard Peris, if you have a bug in Ubuntu, could you please file a new report by executing the following in a terminal:

I could try the steps Joseph Salisbury suggest to gather more information, but can I do this without corrupting my current installation of ubuntu 12.10? this because it's my main computer.

ERROR: The launchpadlib Python module is not installed. This functionality is not available.

Apport does not work any more in ubuntu 12.10. Seems to be the same with other users. I assume this is by choice and I wont file a bug report about this.

[2green (zendhetmij)]

@ Christopher M, thanks for the suggestion. Although I was more concerned about corrupting my ubuntu install.

Your instructions are apreciated, very easy to follow.

Could you please perform the apport-collect following https://help.ubuntu.com/community/ReportingBugs#Error:_The_launchpadlib_Python_module_is_not_installed ?

As well, could you please test http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc3-raring/ ?

Thank you for your understanding.

@Christopher M. Penalver:

Thanks for the apport instructions. Apport information is added.

Just retested with kernel 3.7 rc3. This solves a part of the problem. With kernel 3.7 rc3 my brightness settings are remembered. But using the Fn+F9 keys to decrease brightness and Fn+F10 to increase brightness still has no result.

[penalvch (penalvch)]

2green, thank you for apport-collect'ing. Regarding your comments https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1063804/comments/30 :
>"With kernel 3.7 rc3 my brightness settings are remembered. But using the Fn+F9 keys to decrease brightness and Fn+F10 to increase brightness still has no result."

As we have two different problems, Fn+F9/F10 toggling brightness, and brightness settings remembrance, let this report focus on just Fn+F9/F10 toggling brightness.

For more on this, please see the Ubuntu Bug Control and Ubuntu Bug Squad article:
https://wiki.ubuntu.com/Bugs/BestPractices#X.2BAC8-Reporting.Focus_on_One_Issue

and Ubuntu Community article:
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette

You are welcome to file a new report about brightness settings remembrance via a terminal:
ubuntu-bug linux

and feel free to subscribe me to it.

Hence, could you please test http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc4-raring/ ?

[2green (zendhetmij)]

Christopher, just tested with RC4. With this kernel the problem is fixed.

Didn't know what to do with bug report. For now i've set it on confirmed.

I'm going back to stable kernel 3.5 inless you have other tests to run for me.

p.s.
brightness settings are also solved with kernel 3.7, is there a need for me to report this? Does it help anyone?

[Kirill Kozlov (kirill-kozlov)]

I have HP Compaq 6510b and fn keys for brightness not working.
On Ubuntu 12.04 was worked fine.

[penalvch (penalvch)]

2green, thank you for your comments. I've engaged the Ubuntu Kernel Team on the next step for this report at https://lists.ubuntu.com/archives/kernel-team/2012-December/024197.html .

[penalvch (penalvch)]

2green, could you please test this in Raring via http://cdimage.ubuntu.com/daily-live/current/ and comment if the issue is reproducible in it?

[Kirill Kozlov (kirill-kozlov)]

Ubuntu 12.10
HP Compaq 6510b
Fn keys for brightness controll start working after the last update.

[Ivo Roghair (ivo-82)]

I can confirm that for HP 6710b, the recent update fixed the problem.

Thanks all!

[2green (zendhetmij)]

Problem solved on ubuntu 12.10.

Great job! Thanks.
