My OS is raspbian jessie and I run ROS on my mechine. when I executed "rosrun rviz rviz", I came across the problem: segmentation fault.

Xlib:  extension "RANDR" missing on display ":1.0".
[ INFO] [1464613179.571870535]: rviz version 1.11.14

[ INFO] [1464613179.573252712]: compiled against OGRE version 1.9.0 (Ghadamon)   
Segmentation fault

so I try "gdb rviz rviz", and here is my detail information:

I don't understand what does this mean. Anyone could do me a favour and give me some clues. Thanks a lot!

Please let me know if I can provide more information.
