Thank you, I see it, Even if it might not be the problem here, I could have run into some issues later on with compatibilities.

Hi Everyone,

I just started that school project in which I have to work with gazebo to simulate turtlebots that we should receive soon. I am using ubuntu 12.04 on an old PC that the school provided us. ROS Hydro and GAZEBO 4.0 were already installed prior to the start of my project. I have not much knowledge on any of those programs yet but I have encountered a problem which seems to result from the computer not being able to handle GAZEBO.

I tried to run the tutorial given on the GAZEBO website but I run in an error as soon as I run GAZEBO, it tells me "Too many ALU instructions Using a dummy shader instead". Then GAZEBO opens with a black floor, grey sky. Only the wheels of the robot are red, the rest of the robot is black. What is the source of my problem?

I really appreciate any feedback you guys can provide me.

Thanks,

LOST STUDENT
