2013-05-23 09:26:07 -0500	asked a question	Gazebo Plugin Tutorial error I am running Gazebo with ROS Electric on Ubuntu 10.04 and I have been trying to do the Plugin tutorial. At Step 6, after trying roslaunch, I get the following error: `ERROR: cannot launch node of type [gazebo/gui]: Cannot locate node of type [gui] in package [gazebo]` tmp/buildd/ros-electric-simulator-gazebo-1.4.15/debian/ros-electric-simulator-gazebo/opt/ros/electric/stacks/simulator_gazebo/gazebo/build/gazebo/server/rendering/OgreAdaptor.cc:187 : Exception: Ogre TextureManager initialization failed.

Error Loading Gazebo /tmp/buildd/ros-electric-simulator-gazebo-1.4.15/debian/ros-electric-simulator-gazebo/opt/ros/electric/stacks/simulator_gazebo/gazebo/build/gazebo/server/Simulator.cc:309 : Exception: Failed to Initialize the Rendering engine subsystem /tmp/buildd/ros-electric-simulator-gazebo-1.4.15/debian/ros-electric-simulator-gazebo/opt/ros/electric/stacks/simulator_gazebo/gazebo/build/gazebo/server/rendering/OgreAdaptor.cc:187 : Exception: Ogre TextureManager initialization failed. Please double check your world file or glx support from your gpu / gpu driver, thank you. The world file I am using is straight from the tutorial. My graphics card is an ATI Radeon HD 4200, which is on Gazebo's list of working cards. Could this be an issue with paths?
2013-05-22 08:28:18 -0500	asked a question	Gazebo GUI flickering I'm using Gazebo with ROS Electric on Ubuntu 10.04. The first 3 or 4 times I opened an empty world with Gazebo, it worked fine, but lately launching Gazebo causes the simulation visualization part of the GUI to flicker, although the physics, etc. of the simulation work fine. Has anyone else faced this issue?
