QXcbConnection: Could not connect to display
I am running Raspbian Stretch and ROS Kinetic on a Rpi 3B+.
I have successfully built the ROS Desktop option, but I am getting the following message when using the roslaunch rplidar_ros view_rplidar.launch command string"
QXcbConnection: Could not connect to display [rviz-3] process has died [pid 7994, exit code -6, cmd /opt/ros/kinetic/lib/rviz/rviz -d /home/pi/rplidar_ws/src/rviz/rplidar.rviz __name:=rviz __log:=/home/pi/.ros/log/bf3bc964-d237-11e9-a538-b827ebcb393e/rviz-3.log]. log file: /home/pi/.ros/log/bf3bc964-d237-11e9-a538-b827ebcb393e/rviz-3*.log
Viewing the RPLidar output using the Test application commands works fine:
roslaunch rplidar_ros rplidar.launch rosrun rplidar_ros rplidarNodeClient
Since I am new to ROS programming, can anyone tell me why I am getting the error with the rplidar.rviz function?
