in xev, no event happens when i press fn+F6 (hotkey to enable/disable touchpad).
In windows, this hotkey works

[Joseph Salisbury (jsalisbury)]

Do you recall what kernel you were running when the hotkey worked?

[FelipeAF (felipealexandref)]

Hi, some days after, back to work here... I don't know if a update fix it. Should i change status to fix released?
* i don't recall the kernel versions that happens it.

hi

I have the same laptop lenovo g470 .. and the Fn+arrows are working as expected

but i am running this ubuntu kernel on a debian rootfs :
Linux version 3.1.0-030100-generic (root@gomeisa) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #201110241006 SMP Mon Oct 24 14:07:10 UTC 2011

Regards

ps: your bios is not up to date can you backup it before upgrade ?

[FelipeAF (felipealexandref)]

Hi! The bug recurred :( I did a update yesterday which probably caused it. Today i try disable and noticed thatdisable don't works again. I do not know which packages have been updated (there are some log in somewhere?), but the only kernel version installed in synaptic is linux-image-3.0.0.12-generic in version 3.0.0-12.20. I always was running the same version of bios. when works or not.

bios version: 40CN09WW(V2.07)
ec version: 40EC08WW(V2.07)

BTW do you have an image of your bios or can you backup one of this :

Here some times happens, but in most of time no. However, when the bug happens, reboot seems not fix it. I have dual boot, and most of time i use ubuntu. I think it bug in linux may be related to entering the windows and perhaps enable and disable this.

It looks it is also affecting lenovo-y570 :

FelipeAF, 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? If so, could you please test for this with the latest development release of Ubuntu? ISO 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. Please do not test the daily folder, but the one all the way at the bottom. 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-v3.11-rc5

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

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.
