Change the keyboard layout in LightDM

keyboard-layoutlightdm

I installed LightDM on an Arch Linux system (using pacman) and it runs fine, except, that if I try to type a special character (like "@", "$", …) in the user or password field it doesn't do anything. I'm using the gtk3 greeter, but it doesn't work with other greeters aswell.

I configured the keyboard and the locale like described in the Arch Linux installation guide and it also says in the top right corner of LightDM "de_DE.utf-8".

The problem was that I forgot the file /etc/X11/xorg.conf.d/20-keyboard.conf . I created it with the content:

Section "InputClass"
    Identifier "keyboard"
    MatchIsKeyboard "yes"
    Option "XkbLayout" "de"
    Option "XkbVariant" "nodeadkeys"
EndSection

and now LightDM works.

Adding a custom keyboard layout (and setting it as the default)

Add an entry for the layout to /usr/share/X11/xkb/rules/xorg.lst under ! variant and add the layout to /usr/share/X11/xkb/symbols/us. Then it will be a variant of the us layout. Format of the entry to xorg.lst should be obvious from other entries. If you want the layout listed as a separate language, put the entry in xorg.lst under ! layout and the layout to a separate file name of which is the name of the layout.

Linux – Change lightdm keyboard layout US to Portuguese Arch Linux

Ok, I have found the answer to my question, I believe that it can be applied to other languages than Portuguese.

The LightDM keyboard layout to Portuguese is done with this command:

localectl set-x11-keymap pt

I did this as root, and I think it is the right way, but you can do it has a normal user too, I believe.

I've found this on Fedora forum.

For set-x11-keymap to work, first, we need to install package libxkbcommon, without that will give you an error message.

I've found it on ArchLinux forum.

UPDATE

I asked this question also in Arch Linux forum and this answer, solves the problem too, adding to the file /etc/X11/xorg.conf.d/20-keyboard.conf, these configs:

Section "InputClass"
    Identifier "system-keyboard"
    MatchIsKeyboard "on"
    Option "XkbLayout" "pt"
    Option "XkbModel" "pc105"
EndSection

and reboot...
