Remap Alt_r to Super_R for Cyrillic layout - keycode 108 (keysym 0x0 nosymbol)

I remapped Alt_R to Super_R.

.Xmodmap

Quote

remove mod1 = Alt_R
2 keycode 108 = Super_R
3 add mod1 = Alt_R

But when I change layout to Cyrillic, xev shows keycode 108 (keysym 0x0 nosymbol) for Alt_R.

This breaks switching window groups with tiling window managers.

I don't feel ready to dive into remapping topic, as it seems solutions are not always straight.
On tackexchange people give up to use xmodmap for CapsLock <-> Escape switch, and instead just use
setxkbmap caps:escape.
So ready solution appreceated.

I know you can run things like this as a desktop startup application command, this would put a Euro sign € on shift + left-super (windows key) for example:

Code: [Select]

xmodmap -e 'keycode 133 = Super_L EuroSign Super_L'

At one time I had some problems getting that particular command to work in a browser of some sort incidentally although I can't remember the exact details, but some apps have their own keymappings that might interfere with your changes.
Anyway, when I installed fcitx I had to run xmodmap again manually after the desktop had started, perhaps the keymap was getting reloaded? So I put a delay of 5 seconds (a random selection, didn't try others) on the startup command, and then it worked again.

I remapped ...
But when I change layout to Cyrillic, ...

It is extremely simple and easy.

.Xmodmap

Code: [Select]

clear lock
keycode 66 = Mode_switch NoSymbol Mode_switch
add lock = Mode_switch
keycode 10 = 1 2 3 4 5 6

How to use:

Code: [Select]

1=1
Shift+1=2
AltGr+1=5
AltGr+Shift+1=6
CapsLock+1=3
CapsLock+Shift+1=4

Your task is to replace position 3 and 4 in the Xmodmap file with characters of your choice on the corresponding keys.
When you are done, you have your own keyboard layout with layout switch (CapsLock).

Problem is not with 1 2 3 4 5 keys but with Alt_R.
As I mentioned when I swithch to Cyrillic, Alt_R becomes empty

xev prints

keycode 108 (keysym 0x0 nosymbol)

Instead of

Quote

keycode 108 (keysym 0xffec, Super_R)

My solution is exactly what you are looking for, but you have to implement it yourself.

For problems like this I have used my ./.bashrc file with setxkbmap

such as this to kill the cap locl key that makes me crazy

setxkbmap -option ctrl:nocaps

Code: [Select]

SETXKBMAP(1)                        General Commands Manual                        SETXKBMAP(1)



NAME
       setxkbmap - set the keyboard using the X Keyboard Extension

SYNOPSIS
       setxkbmap [ args ] [ layout [ variant [ option ...  ] ] ]

DESCRIPTION
       The  setxkbmap  command  maps  the  keyboard to use the layout determined by the options
       specified on the command line.

       An XKB keymap is constructed from a number of components  which  are  compiled  only  as
       needed.  The source for all of the components can be found in /usr/share/X11/xkb.

That is with X11 though.
