If you put in XF86Config4
XkbOption "XkbLayout" "us,lt"
or change the keyboard layout directly with
setxkbmap -layout "us,lt" -option "grp:ctrl_shift_toggle"
xmodmap -pm prints
shift Shift_L (0x32), Shift_R (0x3e)
lock Caps_Lock (0x42)
control Control_L (0x25), Control_R (0x6d)
mod1 Alt_L (0x40), Alt_R (0x71)
mod2 Num_Lock (0x4d)
mod3
mod4 Super_L (0x73), Super_R (0x74)
mod5 Alt_R (0x71)
Thus Alt_R is modifier mod1 and mod5. Such situation renders xemacs21 prett=
y =20
unusuable. When pressing Alt it the issues warning
(1) (key-mapping/warning) XEmacs: Alt_R (0x71) generates both Mod1 and Mod=
5, =20
which is nonsensical.
so you practically can't use any meta key shortcuts in xemacs21 and that me=
ans =20
that you can't practicaly use xemacs.
With such configuration setxkbmap -print produces
xkb_keymap {
xkb_keycodes { include "xfree86+aliases(qwerty)" };
xkb_types { include "complete" };
xkb_compat { include "complete" };
xkb_symbols { include "pc/pc(pc105)+pc/us+pc/lt:2+group=20
(ctrl_shift_toggle)" };
xkb_geometry { include "pc(pc105)" };
};
Looking at the file /etc/X11/xkb/symbols/pc you can find lines
default
xkb_symbols "pc104" {
include "pc/pc(basic)"
key <LALT> { [ Alt_L, Meta_L ] };
key <RALT> { [ Alt_R, Meta_R ] };
key <LWIN> { [ Super_L ] };
key <RWIN> { [ Super_R ] };
key <MENU> { [ Menu ] };
// modifier mappings
modifier_map Mod1 { Alt_L, Alt_R, Meta_L, Meta_R };
modifier_map Mod4 { Super_L, Super_R };
};
xkb_symbols "pc105" {
include "pc/pc(pc104)"
key <LSGT> { type[Group1] =3D "FOUR_LEVEL",
[ less, greater, bar, brokenbar ] };
};
In the file /etc/X11/xkb/symbols/lt there are lines
<...skipped>
partial default alphanumeric_keys modifier_keys
xkb_symbols "basic" {
<...skipped>
key <RALT> { type[Group1]=3D"TWO_LEVEL",
[ ISO_Level3_Shift, Multi_key ] };
modifier_map Mod5 { <RALT> };
};
<...skipped>
Thus key RALT or Alt_R in lt layout is assigned to modifier Mod5 and thus t=
he =20
confusion is created.
I am pointing out the problem with lt layout, yet this problem may occur us=
ing =20
other layouts.
Solutions to the problem:
1. Use setxkbmap -layout "lt,us" (us and lt interchanged places, this fixes=
=20
the problem)
2. Comment lines
key <RALT> { type[Group1]=3D"TWO_LEVEL",
[ ISO_Level3_Shift, Multi_key ] };
modifier_map Mod5 { <RALT> };
3. Use setxkbmap -layout "lt(lt_us),lt".
in file /etc/X11/xkb/symbols/lt since in the basic lt keyboard variant no =
=20
third level letters are used.
I use up to date Debian Sid with kernel 2.4.22
