Hi,
Followed ROS Intro / Starting system step by step - Example (ROS introduction | Husarion),
When i get to Starting image view node (ROS introduction | Husarion), and type this code and get the following results:
husarion@husarion:~$ rosrun image_view image_view image:=/camera/rgb/image_raw
[ INFO] [1614828220.890086650]: Initializing nodelet with 4 worker threads.
[ INFO] [1614828221.301916587]: Using transport “raw”
Unable to init server: Could not connect: Connection refused
(image_raw:4056): Gtk-WARNING **: 03:23:41.313: cannot open display:
Segmentation fault (coret dumped)
Please provide suggestions.
Thanks
Vineet
