I never tried a dual monitor (dual head) setup "since display manager"
[1] so I'm just reflecting here

have you configured xorg for dual head?

Archlinux wiki have a simple example:
https://wiki.archlinux.org/index.php/Multihead#Configuration_using_xorg.conf

I think you should adapt it to your needs ("xrandr -q" to show each monitor
ID) and use an extra-config in GuixSD xorg-configuration-file as shown
in this example (raplace bepo-evdev with your dual monitor section
definition):

 https://www.gnu.org/software/guix/manual/en/html_node/X-Window.html#index-xorg_002dconfiguration_002dfile

I don't know if SliM can start a custom display setup script, I found
this gist for Lightdm:

  https://gist.github.com/ciarand/8592193

maybe it could be adapted for SliM

anyway, using the xorg configuration explained above should be better

Ciao
Giovanni


[1] I just used dual head on laptop via xrandr commands, after "sigle
headed" display manager
