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)))
```
