simple config with just startx not working for me

[Andreas Reuleaux]

I am fairly new to guix, thus bear with me please.

I want to start X on my system with startx - i.e. log into my system
just from a tty, and then start X by hand (and i3 will be my window
manager, I just have an .xsession file in my $HOME, where I start i3)
- I do not want any desktop-services / desktop-manager / graphical login manager
(this may seem old school - but has worked fine for me for years
under debian). 

I cannot really get this working though: I have xinit installed (with
startx therein, cf. my config below), but when I

  startx

on the command line, I get this:

    xauth:  file /home/rx/.serverauth.1957 does not exist

    xinit: unable to run server 
"/gnu/store/8v0sja48lmlx5j28hs2mci2rr7v8ilm5-xinit-1.4.1/bin/X": No such file 
or directory
    Use the -- option, or make sure that 
/gnu/store/8v0sja48lmlx5j28hs2mci2rr7v8ilm5-xinit-1.4.1/bin is in your path and
    that "/gnu/store/8v0sja48lmlx5j28hs2mci2rr7v8ilm5-xinit-1.4.1/bin/X" is a 
program or a link to the right type of server
    for your display.  Possible server names include:

        Xorg        Common X server for most displays
        Xvfb        Virtual frame buffer
        Xfake       kdrive-based virtual frame buffer
        Xnest       X server nested in a window on another X server
        Xephyr      kdrive-based nested X server
        Xvnc        X server accessed over VNC's RFB protocol
        Xdmx        Distributed Multi-head X server

    xinit: giving up
    xinit: unable to connect to X server: Connection refused
    xinit: unexpected signal 2

Also, in the guix manual I find an "xorg-start-command" mentioned, but I don't
know how that is supposed to be used (or if I need it at all)? - thus
xorg-start-command is commented out below.

Thanks in advance.
