commit 8b158e8b2cd0293eeebe73f5a71f0c513a89d606

    xorg: honor xorg-configuration-server in xorg-configuration->file
    
    Fixes <https://bugs.gnu.org/40806>.
    
    Previously the xorg-server package specified in the configuration was 
ignored
    entirely in xorg-configuration->file.  This had the effect that while the X
    program of the configured package would be executed, the modules of the
    configured package would be ignored in favor of the default xorg-server
    package's modules.  This fixes that.
    
    * gnu/services/xorg.scm (xorg-configuration->file): honor
      xorg-configuration-server.
