try to subscribe map topic with "$rostopic echo nav_msgs/OccupancyGrid" . could you say me the map has published from gmapping or not?

the Lidar is working and is active... but there is no map. sr1@sr1- Thinkpad-T430:~$ rostopic echo nav_msgs/OccupancyGrid. WARNING: topic [nav_msgs/OccupancyGrid] does not appear to be published yet

You also need to be running the gmapping to see the grid map being formed. Try changing the fixed frame in rviz from map to odom.
