[solved] Special keys not recognized in some applications

[cweiske]

After the upgrade to X 1.6.3 Gtk applications do not detect special keys anymore.
Since I use a macbook, I map the right Apple key to Iso level 3 shift via xmodmap:
> keycode 134 = ISO_Level3_Shift NoSymbol Pointer_Button3

Now I can press <right apple>+l = @ or <right apple>+6 = ]. This works in some applications (xfce terminal, xterm, xev, konqueror, kdiff3), but not in Gtk applications (Mousepad, claws mail, meld etc.) and Opera.
This is my problem - previously it worked, now after the latest upgrade, it does not anymore.
Did someone experience and solve the same problem?

Hi the same is happening with me. Also on a macbook.
There is a Bugreport for Ubuntu: http://ubuntuforums.org/showthread.php?p=7931422. I
I filled one for gentoo: http://bugs.gentoo.org/show_bug.cgi?id=281755
But no reaction so far. I was beginning to think that I'm the only one using gentoo on a macbook.
It still isn't reported upstream, maybe i need to do this.
I tried almost every possible combination with keyboard layouts and models on gnome. Only connecting an external keyboard and choosing explicitly "Right Alt, Shift+Right Alt key is Multi_Key" in gnome-settings get the left alt-key (AltGr) to work in gnome (gtk-applications). Terminal apps work just fine. But i don't want to go to mutt again ...
Seems like a bug in GTK+ or gnome.

I found a solution to this problem, thanks to a german post: http://forum.ubuntuusers.de/topic/third-level-chooser-und-gtk/#post-2112685.
Probably a change, doubling the mapping of "ISO_Level3_Shift", in xorgs xkeyboard-config triggerd a bug in GTK+: https://bugs.freedesktop.org/show_bug.cgi?id=19500

A fix would be to clear mod4 with xmodmap or as a workaround change /usr/share/X11/xkb/symbols/pc, removing the line with Mod4. Apparently a patch for xkeyboard-config would the best.

Thanks! That worked for me, too.
