    common: Reload settings when CanGraphical flips
    
    If GDM starts faster than graphics initialize, then the
    udev rules that write out /run/gdm/custom.conf might get
    run too late for GDM to notice.
    
    This commit changes GDM to reread its config when CanGraphical
    flips from false to true.
