Hello

I'm using ubuntu 16.04 LTS subsystem on WIN10, and I follow the guide to visualize the Kitti data without maskrcnn. The catkin_make is completed and when I run the roslaunch kitti_ros kitti_ros_node.launch but I can't get the picture which shared in Github.

rviz is started but no lidar/picture played in rviz window. I recevied below error in terminal window.

QXcbConnection: XCB error: 170 (Unknown), sequence: 163, resource id: 90, major code: 146 (Unknown), minor code: 20

I'm not sure what the root casue is, it is regarding to the WIN 10 linux subsystem issue, or anything wrong with my ROS environemnt?

Hi, I have not met this problem, I think this is caused by the limitations of virtual machine itself. do you have access to an Ubuntu machine ? Sorry but cannot help much on this since I haven't worked on virtual machine in windows

Hello, I tried in Windows Subsystem for Linux(WSL) and Ubuntu 16.04 both, they all have this problem. Finally I reinstall the pcl 1.8 which is required in source code, this issue fixed. Before that original pcl 1.7 and pcl 1.10 are installed in my environment. I think the problem is the PCL library not compatible.

thanks.
