Red Hat Bugzilla – Bug 810409
Function keys for lcd brightness and wireless does not work on HP Folio 13 laptop
Last modified: 2014-10-08 04:02:50 EDT
Created attachment 575568 [details]
Description of problem:
FN+F2+F3 keys for changing LCD brightness does not work.
FN+F12 (enable/disable Intel Centrino 1030 Wireless/bluetooth combo card) does not work.
Switching "actions keys mode" to disable in BIOS (so that you have to use the fn key + other key as usual) does not help.
xev reports nothing when pressing these keys. Other actions keys like for the led backlit keyboard works)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Unable to enable wireless (hardware disabled)
Unable to ajust lcd brightness via action keys
Adjusting LCD brightness via fn+f2/f3 keys should work.
Enable/disable wireless should work.
acpi_listen does not output anything on these keys.
After additional trial and error I've got wireless to work.
hp-wmi kernel module needs to load at boot for this to work but it is somehow blocking the wireless after boot.
After boot simply remove the hp-wmi module:
Wireless immediately picks up wireless networks and you can connect and use it.
Blacklisting hp-wmi kernel module does not work.
This trick does not work in RHEL 6.2. ( Older hp-wmi module? )
(Wireless button still doesn't work but atleast you can use wireless this way.)
This trick does not work in RHEL 6.3 so there is currently no way to enable the Intel wireless 1030 card. If this gets fixed for Fedora could you please backport this to RHEL6.
I can confirm that the rmmod workaround does at least get the wireless going. hp-wmi must need some kind of keymap update?
I believe this one corresponds to https://bugzilla.kernel.org/show_bug.cgi?id=43097
Are you still having issues with 3.8.2 in updates-testing?

I'm not sure why I've CCed myself on this bug :-) but just FYI, my results with recent version:
$ uname -a
Linux kvolny.usersys.redhat.com 3.8.2-206.fc18.x86_64 #1 SMP Fri Mar 8 15:03:34 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
after switching to text mode, the function keys do not work
but that's Lenovo T510 => not cleaning NEEDINFO, can some HP Folio owner test this?

Also confirmed that acpi_listen is _not_ reporting output for wifi/brightness keys.
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. 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 '17'.
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 17'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 17 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, you are encouraged change the
'version' to a later Fedora version prior to Fedora 17's end of life.
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.
Confirmed that this is _not_ working on Fedora 19 as well.
Looks like this might be fixed in kernel v3.10'ish?

This works for me with 3.10 on Fedora i686: 3.10.11-200.fc19.i686
(I've had to roll back my 3.11 kernel due to a few bugs)
thanks for confirming. Note that the issue preventing you to use 3.11
has been fixed in v3.11.8, so you can move to that one now.
Alexander, ok to close this one?

I just switched to 3.11 (3.11.9-200.fc19.i686) and (re)confirmed that this works as expected on my Folio.
Thanks for the info on the 3.11 fix.
I can't test this as Im on RHEL 6.4 now on a HP workstation laptop.
Given that we have at least one confirmation that things are ok now and that
the original reporter cannot test this, I am closing this BZ.
Remove needinfo. Bug closed.
