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

Try this:

                         (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

Maybe I need to add some (use modules ...) statements? Where should I put (mlet ...) statement?
