Unknown Keycode for Touchpad toggle

[Muelli]

I expected to be able to toggle whether the touchpad works via Fn+F6 on my Lenovo Ideapad S10-3t.

But instead, I get this:
[ 2975.474700] atkbd serio0: Unknown key released (translated set 2, code 0xf2 on isa0060/serio0).
[ 2975.474716] atkbd serio0: Use 'setkeycodes e072 <keycode>' to make it known.

Description of problem:
The key for block/unlock touchpad is not set(HAL,ACPI,setkeycodes), but when i press it, it blocks the touchpad, and i require to suspend, then it back to works.

Version-Release number of selected component (if applicable):
2.6.32.21-166.f12

How reproducible:
always

Steps to Reproduce:
1.press Touchpad button
2.
3.

Actual results:
touchpad button not working correctly

Expected results:
should turn on and off the touchpad... synclient synaptics off 0 or 1 works... but button doesn't

Additional info:

so, it's impossible the button works by itself...

two first lines...
i press the button of touchpad, who are not set, nothing on lshal -m, acpi_listen, udevadm monitor, tailf -f /var/log/Xorg.0.log either messages...

nothing of nothing, but third line said it found a touchpad... so if the button is not doing anything how when i press it, it disable the touchpad?...

[Chuck (chuck-redhat-bugs)]

And does adding "i8042.nomux=1" to the kernel boot options fix it, as suggested in the upstream kernel bug?

[Maximiliano (maximiliano-redhat-bugs)]

well, i found a patch from Kernel to i8042

[Maximiliano (maximiliano-redhat-bugs)]

yes, it works, almost 2 suspend tested... but it have time delays some times, and i detect something, if we have a finger on the touchpad it doesn't unlock it...

well, about the /var/log/messages, i get:

[Maximiliano (maximiliano-redhat-bugs)]

why this are managed by the driver? this could have a lock/unlock function into input.h (kernel keycodes)...

This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '12'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 12's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 12 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

[Maximiliano (maximiliano-redhat-bugs)]

This is managed by a kernel driver, i8042
i resolv this using "i8042.nomux=1" at kernel boot line.

But this should be fixed by default, with no interaction of the users... because i have to search a lot to get it working, lot of options.

This could be managed by the kernel keycodes, or something what can be managed by the user

[Jeremy Foshee (jeremyfoshee)]

Hi Muelli,

If you could also please 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.

Still doesn't work with

I tried "showkey" on the console (i.e. Ctrl+Alt+F2) and it didn't show anything at all. Also, the message in dmesg is the same as reported.

Still does not work.

I can confirm this issue too on Lenovo G460. Only touchpad toggle key doesn't work.

[AceLan Kao (acelankao)]

I just happened to see this bug and wonder if the following steps useful

modify the file /lib/udev/keymaps/lenovo-ideapad
0xf2 unknown # trackpad enable/disable (does nothing in BIOS)
change the above line to
0xf2 f21

Reboot, and try

Muelli, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, 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>

[penalvch (penalvch)]

OR using EOL release, and no response since 2013.
