CJK font issues on GDM screen

CJK font issues on GDM screen

[Taiju HIGASHI]

Hi,

I am not currently having trouble, but I do have one question.

I have had trouble displaying CJK fonts on the GDM screen.

I have followed the steps below to install Guix initially, which
allows me to temporarily display CJK fonts on the GDM screen.

1. Specify `ja_JP.utf8` as locale on the graphical installation screen.
2. Set CJK fonts to be installed globally.
3. Execute the installation.

However, if I run `guix system reconfigure` after this, I cannot see
the CJK fonts on the GDM screen. (The letters will be tofu.)

I asked on #guix on IRC and was given a solution, so I am not
troubled, but the following questions remain.

https://logs.guix.gnu.org/guix/2022-04-09.log#174359

  1. Why do I see CJK fonts on the GDM screen after setting the locale
     and installing CJK fonts during the initial installation?
  2. Why can't I see CJK fonts on the GDM screen after running `guix
     system reconfigure`?

Is there a special process to generate a font cache during initial
installation?
Also, is that process absent when the system is reconfigured?

I feel that it would be desirable for the system to behave the same
when reconfigured as when initially installed.

Thank you.

I have faced the same problem, so I have switched to use slim, which 
*only* show English, so have no this problem :-\

I knew it.
I know there are not many Guix users in Japan, but I was wondering how other languages users are solving this problem.
Is this problem that does not occur with SLiM?

I do not know, slim just show English, do not use CJK.

The problem is that gdm can not find a CJK fonts.
you can try:

              (modify-services %desktop-services
                 (gdm-service-type
                  config => (gdm-configuration
                             (inherit config)
                             (gnome-shell-assets
                              (list adwaita-icon-theme
                                    ;; the below is a CJK font                        
                                    font-wqy-microhei)))))

Maybe we should add an example to guix document.
