Hi Guix!

After upgrading Guix from c9cd16c630 to 188d18fc47, SDDM fails to start
and drops me onto a black screen. I heard from another user on IRC who
seemingly has the same issue, so I think there's a bug here and it's not
a "me" issue.

From the log, it seems like it might something to do with sddm-helper
communicating with PAM. Normally a line like "[PAM] Conversation with 1
messages" is printed after "[PAM] Authenticating..."

My SDDM configuration:

Toggle snippet (6 lines)
(service sddm-service-type
(sddm-configuration
(theme "guix-simplyblack-sddm")
(themes-directory (file-append guix-simplyblack-sddm-theme "/share/sddm/themes"))))

An sddm.log entry when it fails to start:

After updating to 4e7337536ba41e888a601c92fada8a4adca9d2c6, the issue
seems to have been resolved. I'll leave this open in case anyone else
who experienced the issue earlier is still dealing with it.

SDDM fails to start, black screen on 188d18fc47

I ran into this issue on my newly installed laptop (Guix System).

Even after reconfiguring to 15a523ea213065c275e4852673cbb27c72c0ad87
(current master as of today), the screen stayed black and SDDM didn't start.

My sddm configuration:
```
(service sddm-service-type
(sddm-configuration
(display-server "wayland")))
```

So in the end I switched back to GDM which works :)
