我试图在Amazon EC2上的Ubuntu实例中通过Xvfb运行ParaView。我按照http://mike.ucoz.com/publ/programming/ubuntu/selenium_ubuntu_amazon_ec2_headless/8-1-0-4
安装了X11 / Xvfb相关软件包但我似乎无法解决与swrast库相关的错误。
以下是启动Xfvb时的消息

我上面看不到任何戏剧性的东西。但是在运行glxinfo时
$ glxinfo

假设您已安装xvfb-run，可以尝试使用：
xvfb-run --auto-servernum -s "-screen 0 640x480x24" <something_that_needs_X11>

Amazon EC2使用Nvidia GPU，因此问题可能是由NV驱动程序造成的。
试试吧，根据我的dockerfile Dockerfile_cuda80
使用docker容器运行它此dockerfile基于官方cuda图像，经过修改后可以使用OpenGL运行所有cuda样本，你应该使用nvidia-docker来构建＆amp;跑吧。
这解决了我在通过WINE运行Windows程序时遇到的类似问题。
