Description yuyichao 2012-04-02 21:09:43 UTC

I use xkb to redirect certain keybindings to arrow key (C-npbf -> <Down><Up><Left><Right>). Before [this patch](http://patchwork.freedesktop.org/patch/9144/), gtk3 programs
    1, recognize a C-npbf event when I simply press npbf
    2, C-npbf are also being recognized incorrectly (seems like M-npbf but not sure)
    3, there is `Gdk-WARNING **: Event with type {8,9} not holding a GdkDevice. It is most likely synthesized outside Gdk/GTK+` error message generated when pressing C-npbf.

(1 and 2 also happen in wireshark.)

After the above patch, the npbf keys are recognized correctly (problem 1 disappear and 2 also disappear for wireshark), but problem 2 and 3 are still there for all gtk3 programs (I suppose this is a special case that the patch author haven't considered?).

According to the discussion of the patch, I think this can/should be fixed in x server (and also seems to be half-way fixed).

My configuration of one redirection key looks like this.

    key <AB05> {
        type= "EMACS_KEYS",
        symbols[Group1]= [b, B, Left, Left],
        actions[Group1]= [NoAction(), NoAction(),
                          RedirectKey(keycode=<LEFT>,
                                      clearMods=Control),
                          RedirectKey(keycode=<LEFT>, mods=Shift,
                                      clearMods= Control)]
    };

Distro: Arch Linux x86_64 with [testing] enabled
xorg-server: 1.12.0.901-1 from Arch Official Repo (I suppose the xkb patch has already been included in this release.)
Gtk3: 3.4-1 from Arch [testing]

THX for the xkb patch anyway. At least gtk3 programs are "useable" now. (although have some problem with shortcuts.)

Comment 1 Andreas Wettstein 2012-04-03 12:09:30 UTC

There is a reworked version of the patch:

  http://patchwork.freedesktop.org/patch/9252/

> xorg-server: 1.12.0.901-1 from Arch Official Repo (I suppose the xkb patch has already been included in this release.)

I looked at xorg-server-1.12.0.901.tar.gz from cgit.freedesktop.org, 
the patch is not included there (neither 9144 nor 9252).  I also do not see 
how it would fix your issue 1; that was probably fixed by another change.

So, it makes sense to try patch 9252. I suppose it will at least address 
issue 3 (the warnings).  If C-n misbehaves as C-Down, C-p misbehaves as C-Up,
it probably also fixes issue 2.

I C. so somehow the most weird problem is fixed somewhere~~~ I might guess gtk3.4 but~~ don't know......

I might test the git version when I have time to find out the how to compile that (since the PKGBUILD in aur is broken).

Thx again for the fix I have waiting for a long time. Close for now. Reopen if git version (or a future release with the patch included) still has problem.
