Wayland setup

[Thorsten Wilms]

Hi!

Potentially switching distributions seemed like a good opportunity to 
try Wayland, especially since I'm playing with the idea of writing a 
schemey WM; doing so based on X11 seems like wasted effort at this point.

I would like to have a system with just a floating-window Wayland 
compositor installed (Weston?) and the least amount of Gnome and Xorg 
dependencies.

My understanding from the documentation is that the default login 
manager Slim doesn't deal with Wayland. The only alternative seems to be 
sddm. %desktop-services would bring in Slim, AFAICS, so I tried to do 
without and list things explicitly.

Surprised to see Wayland handled via xorg service, _trying_ to make 
sense of the documentation, I ended up with
(service xorg-service-type (sddm-configuration (display-server 
"wayland")), but commented it out to get beyond yet another error 
message on the way.

Actually, I would be OK with logging in on a VT and type whatever the 
Wayland equivalent of startx might be.

What's behind (banana-service) vs (service banana-service-type)? Maybe 
I'm a bad reader, but the documentation left me guessing / piecing it 
from examples, which form to use, except that the later seems to allow 
configuration?

I'm also a bit on a loss on what I actually need regarding networking 
services. During installation, "ifconfig enp5s2 up; dhclient -v enp5s2" 
was sufficient. No Wifi here, just one wrong device enp2s0 to avoid.

My attempt:

(use-modules (gnu)
             (gnu packages freedesktop) ; guix suggested this one
             (gnu system nss)
             (gnu services networking))
(use-service-modules admin avahi base dbus desktop mcron networking sddm 
ssh xorg) ; desktop was suggested for elogind
(use-package-modules base idutils bootloaders certs ntp)

(operating-system
  ...
  (packages (cons* wayland
                   weston
                   nss-certs ;for HTTPS access
                   %base-packages))

  (services (cons* ;(colord-service) missing the right service module
                   (elogind-service)
                   (dbus-service)
                   (polkit-service)
                   (service mcron-service-type)
                   (service network-manager-service-type)
                   (service rottlog-service-type)
                   (sddm-service)
                   (service wpa-supplicant-service-type)
                   ;(service xorg-service-type (sddm-configuration 
(display-server "wayland")))
                   %base-services)))

  ;; Allow resolution of '.local' host names with mDNS.
  ;(name-service-switch %mdns-host-lookup-nss))


I was dismayed to see lots of Xorg stuff scroll by and ending up with 
5,6G on the second generation, before even installing any applications.

If one should do a guix pull before init, 
https://www.gnu.org/software/guix/manual/html_node/Proceeding-with-the-Installation.html#Proceeding-with-the-Installation 
should say so. I only recalled having seen that somewhere else, afterwards!


Got collision warnings at the end of init, whatever that means:

Any help getting closer to my goal appreciated!
