Hello there!
Well, I need help...
## Context:
* I have just a little familiarity with Guile Scheme, because I'm a
LilyPond user;
* I finally have a desktop that doesn't need non-libre drivers;
* Although I'm not in the Tech world, I love GNU's (and the FSF's)
philosophy;
* I have been playing with Nix, but find it very cryptic -- not easy
to understand at all.
So, Guix seems to be the path I'm on now.
## Situation:
I have several problems to fix, but the most important right now is
to get my keyboard to work with sddm, and I need sddm for
Wayland. So, without sddm, this works:
```
...
(define %this-keyboard (keyboard-layout "br" "abnt2"))
...
(operating-system
...
(keyboard-layout %this-keyboard)
... )
```
But `guix system reconfigure /etc/config.scm` fails when this is this:
```
(use-modules
(gnu)
(gnu system nss)
(gnu services networking)
(gnu services sddm)
(gnu services cups)
(gnu services desktop)
(gnu services ssh)
(gnu services xorg))
...
(define %this-keyboard (keyboard-layout "br" "abnt2"))
...
(operating-system
...
(keyboard-layout %this-keyboard)
...
(services
(append
(list
(service dhcp-client-service-type)
(service ntp-service-type)
(service gpm-service-type)
(service cups-service-type)
(service elogind-service-type)
(service sddm-service-type
(sddm-configuration
(display-server "wayland")
(numlock "on")
(theme "guix-simplyblack-sddm-theme")
(xorg-configuration
(keyboard-layout %this-keyboard)))))
%base-services))
... )
```
Then, when I try to run `guix system reconfigure /etc/config.scm`, I
get this backtrace:

## Conclusion:
Two things tell me that the problem is really in the keyboard
configuration within the configuration of the sddm service:
* When I remove the `xorg-configuration` from the `sddm-configuration`,
the reconfiguration returns no error, and the sddm service works
normally.
* And in this setup, the keyboard works on the console, just not on the
desktop environment.
Best regards,
And thank you.
