HI everybody,

I am getting an error when trying to run rviz. I search everywhere, looked
up troubleshooting pages, FAQ, previously posted questions, and Ogre website
and could not find anything useful.
When I enter "rosrun rviz rviz" I get the following output:

[ INFO] [1285443273.197913669, 58.446000000]: Loading general config from

I own a PC with Windows 7 but I have installed Ubuntu  10.04 LTS (the Lucid
Lynx)  in a separae partition and I have 2 GB free space. I have installed
all of the required packages and I am able to run all of my desired modules
including gazebo, Pr2 simulator, etc. As far as revisions, I got the latest
stable version from repos just few hours ago so everything should be the
latest version.

 I followed the followings instructions to install rviz:

rosdep install rviz
rosmake rviz
rosrun rviz rviz

Can you please help me on this?
Thanks
Aidin
