I want to remove gdm-service-type from %desktop-services because I don't
know how to make gmd-service-type use Sway, so I'd rather launch sway
manually after logging in with my user.

The reason I want to remove gdm-service-type from %desktop-services is
because whenever I boot my system, my system switches to tty7 and GNOME
Display manager is shown. After logging in in EXWM Display Manager, EXWM
is started. I don't want EXWM to be started, because I want to use Sway.

I have two questions:

1. How to avoid the automatic visit to tty7 and the execution of GNOME
   Display manager?

2. I wouldn't need to answer the first question if I could make GNOME
   Display Manager to use Sway (currently, it only uses EXWM and I don't
   see a button to change the window manager from EXWM to Sway)

Hi Rodrigo,

(answering in reverse order because I think that makes more sense)

According to the Guix manual’s entry for gdm-service-type:

     GDM looks for “session types” described by the ‘.desktop’ 
     files in
     ‘/run/current-system/profile/share/xsessions’ (for X11 
     sessions)
     and ‘/run/current-system/profile/share/wayland-sessions’ (for
     Wayland sessions) and allows users to choose a session from 
     the
     log-in screen.  Packages such as ‘gnome’, ‘xfce’, ‘i3’ and 
     ‘sway’
     provide ‘.desktop’ files; adding them to the system-wide set 
     of
     packages automatically makes them available at the log-in 
     screen.

I think the solution to your problem may be as simple as adding 
`sway' to your operating-system’s `packages' list, then selecting 
the Sway session type in GDM, by clicking the gear icon in the 
lower-right after entering your username.

Your system config looks correct to me, so I’m not sure what’s 
wrong.  Did you run `sudo guix system reconfigure' after editing 
your system config?

On the VT swtiching behavior, I believe that’s how Xorg is set up, 
and it’ll continue to do that no matter what display manager you 
choose.  I may be wrong.

If I recall correctly, something in /var/lib/gdm is notorious even in other 
distribution for its ability to call GDM when not asked. The usual advice was 
to rm -r the directory. DO double check this advice, as I do not trust my 
memory on this one.

You could also go to the GUIX repository, find the file with the definition of 
%desktop-services and copy the variable definition directly into your file. 
This way you are able to freely inspect and modify the variable to your 
liking. This is what I do with my changes to default data.
