Error message not displayed when GDM fails
Tails 6.0~rc1 introduced a regression: when GDM fails to start (most likely because of unsupported hardware), no text is shown to the user.
see:
config/chroot_local-includes/usr/libexec/gdm-wayland-session.tails
To reproduce this, just run Tails adding autotest_broken_gnome_shell
