Re: Since chvt works, the problem must be the keymap

That is interesting. "keycode  67 = F1 XF86_Switch_VT_1" is the output that I
get with "xmodmap -pke" and this command is supposed to return the exact
expressions which can be used with "-e" to set things up. I can only guess that
the format of the expressions is dependent on the general keyboard setup.

I would experiment like this:

xmodmap -e 'keycode  67 = F1 F13 XF86_Switch_VT_1'
xmodmap -e 'keycode  67 = F1 F13 F1 XF86_Switch_VT_1'
xmodmap -e 'keycode  67 = F1 F1 F1 XF86_Switch_VT_1'
xmodmap -e 'keycode  67 = F1 F13 F13 XF86_Switch_VT_1'

It would be interesting to know what works for you and also your general
keyboard setup. For comparison, here is what I have:

$ xmodmap -pke | grep 'F1 '
keycode  67 = F1 XF86_Switch_VT_1

$ setxkbmap -print
xkb_keymap {
        xkb_keycodes  { include "xfree86+aliases(qwerty)"       };
        xkb_types     { include "complete+caps(shift)"  };
        xkb_compat    { include "complete"      };
        xkb_symbols   { include "pc(pc105)+es(nodeadkeys)+compose(menu)"        };
        xkb_geometry  { include "pc(pc105)"     };
};

$ awk '/Section "InputDevice"/,/EndSection/' /etc/X11/xorg.conf
Section "InputDevice"
        Identifier      "Generic Keyboard"
        Driver          "kbd"
        Option          "CoreKeyboard"
        Option          "XkbRules"      "xorg"
        Option          "XkbModel"      "pc105"
        Option          "XkbLayout"     "es"
        Option          "XkbVariant"    "nodeadkeys"
EndSection
