Amazon EC2 Ubuntu + Xvfb：libGL錯誤：未能加載驅動程序：swrast

Question

我試圖在Amazon EC2上的Ubuntu實例中通過Xvfb運行ParaView。我已經安裝了X11/Xvfb相關軟件包根據http://mike.ucoz.com/publ/programming/ubuntu/selenium_ubuntu_amazon_ec2_headless/8-1-0-4

但我似乎無法越過與swrast庫相關的錯誤。

這裏開始Xfvb

我看不到任何東西上面戲劇性當該消息。但運行glxinfo

$ glxinfo

時注意：提前

感謝。

Answer 1

假設你已經安裝了xvfb-run，你可以嘗試用：

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

Answer 2

Amazon EC2上使用了Nvidia的GPU，所以這個問題可以通過NV的驅動程序引起的。

只要給它一個嘗試，與搬運工容器運行的基礎上，我dockerfile Dockerfile_cuda80

這dockerfile是基於官方CUDA圖像，修改運行OpenGL的所有CUDA樣，你應該使用了nvidia-泊塢窗來建立&運行它。

這解決了我通過WINE運行Windows程序時遇到的類似問題。
