Description Marcelo Ricardo Leitner 2011-10-14 12:08:04 UTC
Description of problem:
I have 2 mute buttons on Lenovo ThinkPad T510.
The MIC mute key doesn't work on ThinkPad T510, while output mute key works fine.

Version-Release number of selected component (if applicable):
CSB 6.1, x86_64
6.2 Snapshot 1, x86_64 and also i686
I could reproduce on both versions.

On CSB 6.1:
xorg-x11-drv-keyboard-1.4.0-3.el6.x86_64
kernel-2.6.32-131.12.1.el6.x86_64

How reproducible:
Always

Steps to Reproduce:
1.Boot
2.Start xev
3.Press the mic mute key, you'll see the key has no symbol attached.
  
Actual results:
Nothing happens.

Expected results:
Mute the mic.

Additional info:
xev output:
KeyRelease event, serial 34, synthetic NO, window 0x5800001,
    root 0xb9, subw 0x0, time 94057986, (536,233), root:(542,336),
    state 0x0, keycode 248 (keysym 0x0, NoSymbol), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

it's also followed on dmesg with:
keyboard.c: can't emulate rawmode for keycode 240

I can provide more info if needed.

Comment 2 RHEL Program Management 2011-10-18 18:39:51 UTC
Since RHEL 6.2 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

Seems a very known issue, actually.

Comment 8 Lenny Szubowicz 2017-02-07 21:11:38 UTC
Given the age of this problem report and the current lifecycle stage of RHEL 6 development, I'm closing this request. If this problem is still present and you believe it's serious enough to warrant fixing in RHEL 6, please reopen this BZ.
