Hello,

First, thanks for all the work. 
I don't have time right now but i might look at this soon.
In the meantime, I looked in nixpkgs and they updated not so long ago.
They added this a few months ago:

    services.xserver.displayManager.sessionCommands = ''
      if test "$XDG_CURRENT_DESKTOP" = "GNOME"; then
          ${concatMapStrings (p: ''
            if [ -d "${p}/share/gsettings-schemas/${p.name}" ]; then
              export XDG_DATA_DIRS=$XDG_DATA_DIRS''${XDG_DATA_DIRS:+:}${p}/share/gsettings-schemas/${p.name}
            fi
            if [ -d "${p}/lib/girepository-1.0" ]; then
              export GI_TYPELIB_PATH=$GI_TYPELIB_PATH''${GI_TYPELIB_PATH:+:}${p}/lib/girepository-1.0
              export LD_LIBRARY_PATH=$LD_LIBRARY_PATH''${LD_LIBRARY_PATH:+:}${p}/lib
            fi
          '') cfg.sessionPath}
      fi
    '';
    
It seems to add a few environment variables to start Gnome from the
display manager. FYI, p is any package added to cfg.sessionPath.
It defaults to gnome-shell and gnome-shell-extensiosn. (They also advise
not to modify it and rather patch the package itself so it might just not be
possible for those two.)

I don't know if it's related. I hope it helps tho.

Have a nice day,
