Bug#241034: xlibs: Meta key not working in emacs with XkbOptions altwin:left_meta_win

If (X)emacs used XKB extensions, it could make this distinction, so one could argue that this is a limitation in (X)emacs. But on the other hand, having 2 keys of distinct types (Meta and Super) bound to the same modifier is certainly not a good idea; if these keys handle different actions, binding them to different modifiers is natural.

I filed http://bugzilla.xfree86.org/show_bug.cgi?id=1344 but I am afraid that mapping a key to another modifier might cause other trouble, so let's see what upstream will propose. Thanks for the explanation. If I understand you correctly then from the XFree86 point of view this bug is probably a duplicate of #234081. It seems that people use altwin:left_meta_win mostly because altwin:meta_win cancels AltGr, see http://bugzilla.xfree86.org/show_bug.cgi?id=1341 Right, that was the reason why I went with left_meta_win. But this one can easily be fixed, here is a patch. All *_win options are then handled in a similar manner and do not modify Alt keys. Thanks a lot! I applied your patch in /etc/X11/xkb and am happily using altwin:meta_win now. Denis Felix

And it's not a problem with the Xserver itself, because the problem also occurs with a self-built server from the DRI project that I was using before the XFree86 upgrade without problems. Denis Felix
Bug#241034: xlibs: Meta key not working in emacs with XkbOptions altwin:left_meta_win
Package: xlibs Version: 4.3.0-7 Severity: normal The meta key stopped working after upgrading to XFree86 4.3. This is with XkbOptions set to altwin:left_meta_win, compose:menu. It used to work with XFree86 4.2.x. The left windows-key was Meta. When I remove the XkbOptions I can use left-Alt as Meta key. When I use altwin:meta_win, the windows key works as Meta, but the AltGr key becomes Alt_R and I can't access the 3rd mapping of certain keys (making the german keyboard useless). That's why I really want to use the left_alt_meta option.
