Not sure if this is a bug or misconfiguration.
Here is relevant part of my config.scm

(use-modules (gnu)
               (gnu system nss)
               (gnu services xorg))
(use-service-modules desktop)
(use-package-modules xfce ratpoison wicd avahi xorg certs)
;;;System definition cut away.
   (services (cons* (slim-service #:startx (xorg-start-command
#:configuration-file (xorg-configuration-file #:drivers '("radeon" "vesa")
                         #:resolutions '((1366 768) (1024 768)))))
                   ;;%desktop-services
                   %base-services))

But when I run gux system reconfigure /etc/config.scm I get error:

I believe this is because the return value of
'xorg-configuration-file' is a monadic value, and thus it needs to
"unwrapped" in order to pass the configuration file to
'xorg-start-command'.

Try this:

    (mlet %store-monad ((config
                         (xorg-configuration-file #:drivers '("radeon" "vesa")
                                                  #:resolutions '((1366 768)
                                                                  (1024 768)))))
      (slim-service #:startx (xorg-start-command #:configuration-file config)))

I've tried this

  (services (cons*
(mlet %store-monad ((config
  (xorg-configuration-file #:drivers '("radeon" "vesa")
                           #:resolutions '((1366 768) (1024 768)))))
(slim-service #:startx (xorg-start-command
#:configuration-file config)))
                   ;;%desktop-services
                   %base-services))

But still failed

I've found another possible solution:

https://lists.gnu.org/archive/html/guix-devel/2015-05/msg00395.html

  (define input-class
    "Section \"InputClass" ...")

  (define (my-slim-service)
    (mlet %store-monad ((config (xorg-configuration-file
                                 #:extra-config (list input-class)))
                        (startx (xorg-start-command
                                 #:configuration-file config)))
      (slim-service #:startx startx)))

  (operating-system
    ;; ...
    (services (cons (my-slim-service) ...)))

I'll try it later.

I was getting similar errors when I had stale .go files lying around
from before packages were moved.  The .go files would be picked up
because my os-config.scm included their modules explicitly.  Since this
is in slim and thus guixsd you might be experiencing something similar,
dunno.  Try "find ~/src/guix -name '*.go' | xargs rm" and then rebuild
guix, perhaps.

You can run 'make clean-go' to delete all of the .go files. :)

Where should I run make clean-go?

Anyway, I've tried

# find / -name '*.go' | xargs rm

Didn't help.

And I've tried reinstalling GuixSD from zero with config.scm mentioning
slim-service and #:resolutions. Didn't help either. Same error again. What
should I do now? Should I post my full config.scm? Should I ask you to try
slim-service configuration with #:resolutions ?

I've tried everything. Please help me. I want to help Guix, write new
packages and patches, but I can't. My eyes hurts because of wrong
resolution. Here is my full config.scm:

(use-modules (gnu)
               (gnu system nss)
               (gnu services xorg))
(use-modules (guix))

        (mlet %store-monad ((config (xorg-configuration-file
                #:resolutions '((1366 768)))))
        (slim-service #:startx
                (xorg-start-command #:configuration-file config))))

(operating-system
  (host-name "camelot")
  (timezone "Europe/Moscow")
  (locale "en_US.UTF-8")

  ;; Assuming /dev/sdX is the target hard disk, and "root" is
  ;; the label of the target root file system.
  (bootloader (grub-configuration (device "/dev/sda")))
  (file-systems (cons (file-system
                        (device "/dev/sda1")
                        (title 'guix)
                        (mount-point "/")
                        (type "ext4"))
                      %base-file-systems))

  (users (list (user-account
                (name "camel")
                (comment "Camel")
                (group "users")
                (supplementary-groups '("wheel" "netdev"
                                        "audio" "video"))
                (home-directory "/home/camel"))))

  ;; Add Xfce and Ratpoison; that allows us to choose
  ;; sessions using either of these at the log-in screen.
  (packages (cons* xfce ratpoison    ;desktop environments
                   xterm wicd avahi  ;useful tools
                   nss-certs         ;for HTTPS access
                   %base-packages))

  ;; Use the "desktop" services, which include the X11
  ;; log-in service, networking with Wicd, and more.
  (services (cons* (my-slim-service)
                   ;;%desktop-services
                   %base-services))

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


Have I configured slim-service properly? Do I need to use some modules I
haven't mentioned?

Sorry for the late reply.

The problem is in the line above: ‘xorg-start-command’ is a “monadic
procedure” so its result must be bound in an ‘mlet’:

  (define (my-slim-service)
    (mlet %store-monad ((config (xorg-configuration-file ...))
                        (startx (xorg-start-command ...)))
      (slim-service #:startx startx)))

HTH!

$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
   1024x768       0.00*

Here is some of my lspci. As you can see I have Radeon card:

$ lspci | grep -i radeon
01:05.0 VGA compatible controller: AMD/ATI [Advanced Micro Devices,
Inc.] RS880M [Mobility Radeon HD 4225/4250]
01:05.1 Audio device: AMD/ATI [Advanced Micro Devices, Inc.] RS880
HDMI Audio [Radeon HD 4200 Series]

And here is the answer to the topic question. How to set screen
resolutions? Like this:

(define (my-slim-service)
        (mlet* %store-monad ((config (xorg-configuration-file
;;              #:drivers '("radeon" "vesa")
                #:resolutions '((1366 768) (1024 768))
))
                             (startx (xorg-start-command
                #:configuration-file config)))
        (slim-service #:startx startx)))

But it won't work for me, because of non-free radeon microcode. If I
uncomment #:drivers line I'll get error like this on X startup:

Missing Free firmware
Failed to load firmware "/*(DEBLOBBED)*/"

It looks like Xorg falls back to VESA, which may be why ‘xrandr’ gives
you no choice.  So it’s probably not a GuixSD-specific problem.

I don’t know the status of free drivers for these Radeon cards.  Maybe
http://h-node.org or similar sites have more info?

Thanks,
Ludo’.
