Amazon EC2 Ubuntu + Xvfb:libGL错误:无法加载驱动程序:swrast

Question

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

但我似乎无法通过与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

注意:

提前致谢.

假设您已经xvfb-run安装，您可以尝试：

xvfb-run --auto-servernum -s "-screen 0 640x480x24" <something_that_needs_X11>
