当我尝试使用 rviz 时，出现错误 "Segmentation fault (core dumped)"。详细信息如下所示。我现在用的是两张显卡，一张GTX-750，一张K40，不知道是不是下面这个问题的原因，以及如何解决。

我能做什么？我试过将 OGRE_RTT_MODE 更改为 Copy 或 FBO 的方法，但仍然
检查 RVIZ :
默认建议将使用不带参数的 RVIZ，
$ rosrun rviz rviz
如果这也不起作用，可能是因为配置文件错误。所以，删除 ~/.rviz folder 并重新开始。我曾经遇到过同样的问题，这解决了它。
另外，如果您最近更新了您的 ROS 发行版，您可能还需要更新您的显卡。如果没有，请尝试 RVIZ troubleshouting page.
中的解决方案
检查食人魔：
在终端中，运行以下命令：
$ glxgears
这是一个很好的测试，可以查看 OpenGL 是否在 system/driver 级别为您工作。 （你会得到一个漂亮的 window 机械的东西）
还有
$ glxinfo | grep 'OpenGL renderer'
应该不是说'software rasterizer'，应该是你显卡的型号
如果这些都不起作用，则意味着您的显卡已过时并且 Ogre 无法正常工作。 （这使得它独立于 Rviz）。
卸载 rviz 并从源代码重建它为我解决了这个问题。
正在删除 rviz：
sudo apt-get remove ros-noetic-rviz
从源构建：
git clone https://github.com/ros-visualization/rviz
catkin build rviz
