[ros-users] hokuyo_node error

[Vinay K]

HI Blaise,

Yes I have already checked with VV command that SCIP 2.0 and FIRMWARE 3.3.
Laser is working , this is clear from below given.

vros at powerbot:~$ rosrun hokuyo_node hokuyo_node
[ INFO] 1278719145.793650000: Connected to device with ID: H0507384

seconds.

[ INFO] 1278719149.806085000: Streaming data.

while running rviz command for visulaziation, I got some errors given below
[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

Ogre::GLSupport::initialiseExtensions(): Assertion `pcVer && "Problems

I searched for rviz troubleshooting they have reported the same error there
saying that some graphics driver problem with ubuntu. here is the
