我使用的是 Ubuntu 13.10，最终设法为我的 nVidia 卡安装了正确的驱动程序（使用 bumblebee），glxinfo 最终显示我支持 OpenGL 4.20。所以，最后，对于我正在从事的项目，我需要在 Chrome 或 Firefox（我更愿意在 Chrome 中使用）中运行 WebGL 来测试我正在开发的程序。我相信这可能与我的板载 Intel HD5000 发生冲突？
当我尝试在 Firefox 中运行 WebGL .html 文件时，我在终端中得到了以下信息：

我的 nVidia 显卡是 765GTXM。当我在 Windows 中运行完全相同的文件时，一切都运行顺利。
答案1
我在使用 Chromium 时也遇到了类似的问题（下载 Chrome 时也遇到了）。事实证明，WebGL 仍属于实验性功能，因此默认情况下它处于关闭状态。
要打开它，请在地址栏中输入以下地址：
chrome://flags
然后按回车键（或刷新）。
然后选择 覆盖软件渲染列表
然后您必须关闭 Chrome（或 Chromium）才能使更改生效。
