Hi, I stuck while developing ROS based application. while running 'rosrun rviz rviz', i got error message as 'Segmentation fault' as....

CPU: iMX6Q, OS: Ubuntu Bionic 18, ROS: melodic

I tested the 'glxinfo | grep version', it shows me.....

client glx version string: 1.4
GLX version: 1.4
OpenGl version string: 3.1 V6.2.4.p4.190076
OpenGL shading language version string: 3.00

I tested the 'glxgears', it gives me....

1455 frames in 5.0 seconds = 290.972 FPS
1553 frames in 5.0 seconds = 310.516 FPS

...and so on.

Please suggest. Thanks.
