Yes. After changes in /etc/config.scm and running as root `guix system reconfigure /etc/config.scm` and reboot I've got it!
 Your advice solved! Thank you!



Hello, I think this can be done by set 'handle-lid-switch' to 'ignore'(it's 'suspend' by default) for the 'elogind-service-type', for example:(operating-system  ...  (services    (cons* (xfce-desktop-service)           (modify-services %desktop-services             (elogind-service-type               c => (elogind-configuration                      (handle-lid-switch 'ignore)))))))Hope it helps!
