Subject: sddm does not start after update to 0.20.0
Date: Mon, 5 Feb 2024 23:37:52 +0100

Today I rebooted my workstation running Guix System and somehow sddm
didn't started anymore.

I quickly found a suspicious commit:
05fad99a431c6708ec18c7d0db67178bd8d36597
gnu: sddm: Update to 0.20.0.

Then I pulled and reconfigured to this commit (Generation 14) and to one
commit before (Generation 13). And indeed the sddm update to 0.20.0
breaks my system.

The relevant part of my configuration.scm:

  (sddm-configuration
    (display-server "wayland")))
```

There is an upstream bug report which is maybe relevant:
https://github.com/sddm/sddm/issues/1456

@Feng Shu: I CC'ed you for this bug as you updated the sddm package.
Maybe you are not affected by this issue or have a workaround :)

Hi tumashu,

Thanks for that super fast response! Indeed this was the trick, sddm
works now again without setting the display-server to wayland.

I wonder what we could do in the mean time to save other users from this
pitfall?

Would it make sense to deprecate the `display-server` configuration
parameter in order to always default to xorg?

Or maybe just add a note to the manual:
https://guix.gnu.org/manual/devel/en/guix.html#index-sddm_002dconfiguration

I think, we should let sddm-service-type create the below config:

    CompositorCommand=
    Path of the compositor to execute when starting the greeter. Default value is "weston --shell=fullscreen-shell.so".
