   Return a procedure that transforms an operating system, setting up
   DRIVER (default: nvda) for NVIDIA graphics card.
 
+  OPEN-SOURCE-KERNEL-MODULE? (default: #f) only supports Turing and later
+  architectures and is expected to work with 'linux-lts'.
+
   KERNEL-MODE-SETTING? (default: #t) is required for Wayland and rootless Xorg
   support.
 
-  CONFIGURE-XORG? (default: #f) is required for display managers that can start
-  the Xorg server (e.g. GDM).
-
-  OPEN-SOURCE-KERNEL-MODULE? (default: #f) only supports Turing and later
-  architectures and is expected to work with 'linux-lts'.
+  CONFIGURE-XORG? (default: #f) is required for Xorg display managers.  Currently
+  this argument configures the one used by '%desktop-services', GDM or SDDM.
 
   Use 'replace-mesa', for application setup out of the operating system
   declaration.
