Hi.

This is forwarded from the mentioned Debian bug:

The new version seems to somehow break the F10 key.

When being in GNOME, and havin a gnome-terminal opened, e.g. aptitude running...
pressing F10 should cause aptitude's menu to open.

But now, aptitude's menu opens, as well as the context menu of the
terminal itself.

Downgrading fixes the issue.


Cheers,
Chris.

What I suspect is that some app (gnome-terminal?) somehow checks the key
definition. Why? I have no idea. Something was hardcoded - some
workaround, perhaps - there was an issue with functional keys in 2.4.
But xev output proves there is nothing to fix in xk-c

Actually I am ready to reopen if you explain me what exactly would you

with everybody?

If that's the case, the software is using some other information from
XKB config - which is should not, I guess

Returning to the previous version of F10 definition is not an option
because it had clearly broken semantics of things like Shift-F10.

So, what would you propose to do?

This is not completely true. The new definition of CTRL+ALT consumes Shift,
the old one does not.  With the new definition, in a pedantic interpretation
of section 7.2.1 of the protocol specification of the X Keyboard Extension,
applications must not distinguish Shift-F10 and F10 anymore.

To see wether this is related to problem at hand, one could replace the 
definition of CTRL+ALT (file in types/pc) with the following one:

   type "CTRL+ALT" {
	modifiers = Control+Alt+Shift+LevelThree;
        map[None] = Level1;
        map[Shift] = Level2;
        map[LevelThree] = Level3;
        map[Shift+LevelThree] = Level4;
	map[Control+Alt] = Level5;
	preserve[Shift] = Shift;
	preserve[Shift+LevelThree] = Shift;
	preserve[Shift+LevelThree+Alt] = Shift;
	preserve[Shift+LevelThree+Control] = Shift;
	preserve[Shift+LevelThree+Alt+Control] = Shift;
	preserve[Shift+Alt] = Shift;
	preserve[Shift+Alt+Control] = Shift;
	preserve[Shift+Control] = Shift;
        level_name[Level1] = "Base";
        level_name[Level2] = "Shift";
        level_name[Level3] = "Alt Base";
        level_name[Level4] = "Shift Alt";
	level_name[Level5] = "Ctrl+Alt";
    };

I do not have gnome on my machine, so I cannot test myself.  Note that
the above definition is still not nice, but should be ok to check wether
consumed Shift is to blame.

Do you have a pointer where the problems with the old definition are
described?

How does it affect the behavior of the F10 when shift is not pressed? As you can see, the events are exactly same.

Basically, as Shift is consumed, one should not distinguish F10 and
Shift-F10.  This means that pressing Shift-F10 should be handled like
pressing F10; or that pressing F10 should be handled like pressing
Shift-F10.  So it is imaginable that consuming Shift assigns two functions
to pressing F10: the usual one for F10, plus the one for Shift-F10.

That is the idea.  Whether it happens like this, I do not know.  One has to
try or read the relevant source code.  In any event, the original report
speaks about two actions triggered by F10...

My own investigation confirms the finding in comment 17.
The xkeyboard-config changes in 2.4.1 make XKB translate Shift-F10 into F10 with level one, while telling my that the Shift modifier got consumed.

Also note that xev output being identical is pretty irrelevant here,
since xev only reports the core key events, not xkb data. that can be

Here is a modified type for CTRL+ALT that works in my testing.
It is similar to the one in comment 17, but avoids blowing up the map with lots of new entries.

With this map, XkbTranslateKeyCode still translates Shift-F10 into F10
at level1, but the Shift modifier is now preserved, so GTK+ uses it when
matching  accelerators, and thus F10 and Shift-F10 can once again have
different bindings.

Title:
  Shift + F12 keys don't work in any program

Status in central project for keyboard configuration:
  Fix Released
Status in “unity” package in Ubuntu:
  New

Bug description:
  Description:	Ubuntu 12.04.4 LTS
  Release:	12.04

  byobu:
    Installed: 5.17-0ubuntu1

  Shift + F12 key combination doesn't work.

  Normally in byobu Shift + F12 disables a specific setting, but it
  doesn't in 12.04

  Also in a custom 4gl (Empress) application we have Shift + F12
  normally opens a window, but it doesn't in 12.04.

  Any other program that uses 12.04 has the same issue.  I have tested
  this on 3 machines running 12.04.
