Sounds like your X server is not setup properly for 3D acceleration. What does "glxinfo" output?

Hi,I am trying to use the Stage simulation. I am following the tutorial given on the siteI am able to run the simulation environment and even the commandrosrun teleop_base teleop_base_keyboard base_controller/command:=cmd_velBut I get a very slow response to the inputs typed on the keyboard. I see the robot moving very slowly and after few minutes. Later on the blue robot just disappears from the screen.Do I need to change any parameters in the world file ?I even tried changing the world file tointerval_sim 1 # simulation timestep in millisecondsinterval_real 1 # real-time interval between simulation updates in millisecondsBut I still get the same response.I have one more concern.I was not able to run the commandrosrun rviz rviz -d rviz/stage.vcgI get the following error.No protocol specifiedError: Unable to initialize gtk, is DISPLAY set properly?The result of the command $ echo $DISPLAY:0.0Basically I trying to use ROS for a good simulation environment for my project. Do you recommend me to use Stage or do we have a new simulation environment by ROS ?Thank you.
Regards,
Suraj Swami
