====== Workarounds for Gazebo Intel Graphics Card Issues ======
===== Segmentation faults =====
If you encounter the error
<code>[gazebo_gui-19] process has died [pid 6086, exit code 139, cmd /opt/ros/fuerte/stacks/simulator_gazebo/gazebo/scripts/gui __name:=gazebo_gui __log:=/home/winkler/.ros/log/ba357cea-d1b2-11e1-b926-8c705ac51404/gazebo_gui-19.log].
log file: /home/winkler/.ros/log/ba357cea-d1b2-11e1-b926-8c705ac51404/gazebo_gui-19*.log</code> or similar and you're running on a system with only an Intel graphics card, setting the following ENV variable might reduce the frequency in which this error comes up:
<code>export OGRE_RTT_MODE=Copy</code>
Just add it to your ~/.bashrc.
===== Rough background info =====
The command that actually fails with a segfault is the following:
<code>`rospack find gazebo`/gazebo/bin/gzclient -g `rospack find gazebo`/lib/libgazebo_ros_paths_plugin.so</code>
Once Gazebo launched (but did not display the GUI window) you can run this command to open the gazebo client ui window (instead of launching the gazebo master again).
