[ros-users] RVIZ error

[Vinay K]

Hi,

I was trying to visualize hokuyo laser data in rviz while using hokuyo_node.
Below is the error I am getting..... I need some suggestions although error
is mentioned in the troubleshooting of RVIZ
http://www.ros.org/wiki/rviz/Troubleshooting but still not clear.

 [please note that I am getting the same error if I just call $rosrun rviz
rviz]:
vros at powerbot:~$ rosrun rviz rviz -d 'rospack find hokuyo_node'
/hokuyo_test.vcg
[ INFO] 1278719927.352134000: Loading general config from
[/home/vinaypilania/.rviz/config]
[ INFO] 1278719927.353486000: Loading display config from
[/home/vinaypilania/.rviz/display_config]
rviz: OgreGLSupport.cpp:57: virtual void
Ogre::GLSupport::initialiseExtensions(): Assertion `pcVer && "Problems
getting GL version string using glGetString"' failed.

This error is mentioned in the troubleshooting. According to troubleshooting
Do I need to install graphics driver compatible to my laptop for ubuntu 9.04
or to install OpenGL. Please not that I have installed ROS on other computer
there I am not getting this error [only for $ rosrun rviz rviz  ] but there
I tested slam_gmapping package in the tutorial
http://www.ros.org/wiki/slam_gmapping/Tutorials/MappingFromLoggedData.
 In the end of this tutorial in "3. Variation: watching the mapping
progress", I am getting one error that is "graphics driver does not support
2000*2000" grid/array [approx]. From all these testing it seems that there
is some problem with rviz.

Looking forward for help please.

thanks
Vinay
