A FAQ incrível fornece um answer :
Why does Mod4 "swallow" succeeding key presses?
On some systems xkb by default maps the left windows key to "Multi_key" (at least in us and de layouts).Multi_key
is an xkb feature which may be used to access uncommon symbols by pressingMulti_key
and then (consecutively) two "normal" keys. The solution is to remap your windows key to mod4 and remove the Multi_key mapping. This can be done by including "altwin(left_meta_win)" in the xkb keyboard description xkb_symbols line.
#!/bin/bash
xkbcomp - $DISPLAY<<EOF
xkb_keymap {
xkb_keycodes { include "evdev+aliases(qwertz)"};
xkb_types { include "complete"};
xkb_compat { include "complete"};
xkb_symbols { include "pc+de(nodeadkeys)+inet(evdev)+group(alt_shift_toggle)+level3(ralt_switch)+altwin(left_meta_win)+capslock(escape)" };
xkb_geometry { include "pc(pc104)"};
};
