Shift + Fn Keys Suddenly Don't Work

Hello,

On an ordinary keyboard, the extended function keys, F13 to F24, should
be accessible as Shift + Fn, where Fn are the keys F1 to F12.

Well, up until a few days ago, the Shift+Fn combination was working as it
should. Then suddenly, Shift+Fn stopped working correctly. I noticed
it when using the Midnight Commander (MC) file manager where I extensively
use Shift+F5 and Shift+F6 to conveniently rename and copy files.
MC is a terminal program but the problem also shows up in some X programs
that use Shift+Fn combinations.

Because I have no need to closely monitor changes on my system I can't
actually pinpoint any new install that may be responsible. My first
guess would be a new version of xorg-server-1.11.1 that was emerged
on October 2.

I need to know how I can debug this situation further. Using xev
to record key presses gives the following output when using
Shift+F1:

KeyPress event, serial 40, synthetic NO, window 0xe00001,
root 0x121, subw 0x0, time 6919279, (23,152), root:(463,411),
state 0x0, keycode 50 (keysym 0xffe1, Shift_L), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False

KeyPress event, serial 40, synthetic NO, window 0xe00001,
root 0x121, subw 0x0, time 6921351, (23,152), root:(463,411),
state 0x1, keycode 67 (keysym 0xffffff, VoidSymbol), same_screen YES,
XKeysymToKeycode returns keycode: 63
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False

The data for the F1 keypress is not correct. Compare this output with
the expected output that is shown in this forum thread:
http://forums.gentoo.org/viewtopic-t-524537-start-0.html

It appears that the X server is at fault.

Can anyone using xorg-server-1.11.1 very that the Shift+Fn keys
are broken?

I found this report of the same problem:

http://forums.funtoo.org/viewtopic.php?id=817

The culprit is the new keyboard-config-2.4.1, which I had installed
on October 5. This version breaks the Shift+Fn keys. Downgrading to
version 2.3 solves the problem.

Before filing a bug report with Gentoo, it would be good to have
a confirmation from someone with keyboard-config-2.4.1.

Same problem here. And downgrading to 2.3 fixes it.

Hi Frank,
I've never used the Shift-Function keys myself. Here is what I'm
seeing here using xev to capture Shift-F1:

KeyPress event, serial 30, synthetic NO, window 0x3e00001,
root 0x26a, subw 0x0, time 14761403, (323,554), root:(1606,577),
state 0x0, keycode 50 (keysym 0xffe1, Shift_L), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False

KeyPress event, serial 33, synthetic NO, window 0x3e00001,
root 0x26a, subw 0x0, time 14762104, (323,554), root:(1606,577),
state 0x1, keycode 67 (keysym 0xffbe, F1), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False

KeyRelease event, serial 33, synthetic NO, window 0x3e00001,
root 0x26a, subw 0x0, time 14762163, (323,554), root:(1606,577),
state 0x1, keycode 67 (keysym 0xffbe, F1), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False

KeyRelease event, serial 33, synthetic NO, window 0x3e00001,
root 0x26a, subw 0x0, time 14762733, (323,554), root:(1606,577),
state 0x1, keycode 50 (keysym 0xffe1, Shift_L), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False


I didn't read through the link you posted but it's showing left-shift
& F1, both key on and key off, so I assume it's working correctly
here. This is, however xorg-server-1.10.4 so possibly there's a bug in
the testing version? I still show 1.10.4 as stable but haven't updated
in a couple of days on this machine.

Thanks for taking the time to test, but I may have posted a bit
prematurely again. Further searching has revealed that the problem
is with the newest (and unstable in Gentoo) xkeyboard-config-2.4.1.
This package contains the configuration files for the X keyboards.

Hopefully, the next release will correct things, but otherwise
a downgrade to 2.3 will help if the problem affects you. Most
users probably don't have much need for Shift-Fn.
