Hello! GuixSD is nice for offers to users to have own software sets in one machine. I work with Guix and need more examples on how to write system config. Please, help me to write config.scm to use LXDE desktop with Xfce. Here are presented only xfce-desktop-service, gnome-desktop-service, mate-desktop-service, but no lxde. So here https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/lxde.scm only mentioned packages, but no services. I could only add (use-modules (gnu packages lxde)) but lxde did not appeared in login screen. Pressing F1 gives nothing. Here I could not understand https://www.gnu.org/software/guix/manual/en/html_node/System-Configuration.html#System-Configuration Please, how to set up lxde with xfce and make lxde default? Where can I read about this?
