Hello.
Did you add the boolean value to enable a PAM entry and disable the
setuid entry? Screenlockers usually refuse or complain when started with
setuid due to security.
Also xdg-screensaver is a frontend that is part of the xdg-utils
package. As far as I know, this program is only compatible with
xscreensaver or xautolock, you should try defining one of these
two on the screen-locker-service-type, not xdg-screensaver, and see if
it works.
Example:
```
(service screen-locker-service-type
(screen-locker-configuration
(name "xscreensaver")
(program (file-append xscreensaver
"/bin/xscreensaver")) (using-pam? #t)
(using-setuid? #f)))
```
