Hi Guix,

the right shift key on my laptop's keyboard got stuck. It sometimes
isn't fully pressed, which allowed me to run

    xmodmap -e 'keycode 62='

and disable it, but I need to make this apply in GDM too. I assume I'd
have to specify that in the keyboard-layout record, but both the
documentation and the code aren't too clear on how I'd go about doing
that.

I'd appreciate any pointers.

Regards,
Jakub Kądziołka

Guix writes the keyboard layout in the InputClass section of
xorg.conf.  It seems what you need is more like xkbcomp:

https://wiki.archlinux.org/index.php/X_keyboard_extension#Using_keymap

You could probably use an .xinitrc file like Arch or you could patch
xorg-server to use your xkbcomp map by default.

That is, instead of patching xorg-server, you would patch
xkeyboard-config’s xkb/symbols.  I have not tried.  Maybe better use
.xinitrc?

That's not a terrible idea, though I'd rather have it apply even before
I'm logged in. (I previously mentioned GDM, though I now realize that I
actually use SLiM.) Is there an equivalent file I could use to run a
command when the login manager is starting?

I thought it was sufficient to add the files both to your home
directory and to root’s because SLIM is run as root.

But: Actually it seems the gnu/services/xorg.scm is defined in a way
that does not run ~/.xinitrc.  Sorry for not being helpful.  I tried
but was *not* able to modify gnu/services/xorg.scm to run xkbcomp on a
custom ~/.Xkeymap file, although manual execution after the session
started works fine.  Changing the xinitrc does not appear to work.

The attached changes are insufficient.

Florian

I believe patching the keymaps in xkeyboard-config is the best
solution.
