1464189 – Lenovo T470p volume buttons do not work

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 3 Joseph Kachuck 2017-06-22 17:15:29 UTC

Hello Pgozart,
Please confirm if you are able to recreate this on RHEL 7.3?

Thank You
Joe Kachuck

Comment 5 Joseph Kachuck 2017-06-22 17:20:50 UTC

Hello Lenovo,
Would you be able to confirm if this is tested by Lenovo?

Thank You
Joe Kachuck

Comment 6 Ocean He 2017-06-23 02:41:54 UTC

Hi Pgozart,

I am not fully understanding what's going on here:

Does T470p means ThinkPad T470p? If yes, then Floyd call Peter help on this.

What the RHEL7.4 HTB means?

Ocean.

Comment 7 Joseph Kachuck 2017-06-23 14:29:43 UTC

Hello Lenovo,
HTB means = "High Touch Beta"

I believe T470P means Thinkpad T470P.
Pgozart please confirm this.

Thank You
Joe Kachuck

Comment 9 Wim Taymans 2017-06-26 06:58:51 UTC

First thing to check is if the keys get correctly mapped. Do you see any feedback on the screen that the volume button is pressed, like the gnome volume popup?

Run evtest as root first, and see whether any of the devices in the list respond to the key presses for those keys.

If none do, then it's a driver problem in the kernel.

Comment 12 Christian Kellner 2017-06-27 13:09:17 UTC

Tried to reproduce on a X270 (also a 2017 Lenovo model), but the volume buttons work fine on that machine (btw, FN lock was on by default on this machine, so it was Fn+F2/Fn+F3).

I got the following answers back from the customer.  --Paul

Pressing Fn+F2 and Fn+F3 does not work
Pressing Alt+F2 and Alt+f3 does work.

-----------------------

Tested on 7.3 you can click f2/f3 to change volume, no need to press any additional key.

Specs from lenovo

How do I detect if it is a HIDP?

You're supposed to then choose one of the devices and press the keyboard keys to see if they generate events. I'm guessing "ThinkPad Extra Buttons" on 7.4 is a good place to start.

Comment 17 Christian Kellner 2017-07-11 11:56:01 UTC

I just installed 7.4 Beta on a T470p and I can *not* reproduce the problem: with the exception of the new extra button, the thinkpad buttons, including the volume related ones, work fine.
The kernel: 3.10.0-663.el7.x86_64 with GNOME 3.22.2.

Comment 18 Tomas Pelka 2017-07-11 12:54:56 UTC

I can't reproduce either, let me close as current release.
