安装了视频驱动程序，但没有 WebGL 或 OpenGL 加速工作

Question

我有一个带有 14.04 的戴尔 XPS 13 开发人员版（我第一次在服务器之外认真使用 linux）并安装了 oem 视频驱动程序，但没有任何需要 3d 加速的工作。

lspci | grep VGA 给我：

00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09)

和lshw -c video输出

  *-display

modinfo i915 给我这个

我在另一个问题中发布的 Chrome 中启用了 WebGL，但我得到一个误报，表明一切正常chrome://gpu

Graphics Feature Status Canvas: Hardware accelerated Flash: Hardware accelerated Flash Stage3D: Hardware accelerated Flash Stage3D Baseline profile: Hardware accelerated Compositing: Hardware accelerated Multiple Raster Threads: Enabled Rasterization: Hardware accelerated Threaded Rasterization: Enabled Video Decode: Hardware accelerated Video Encode: Hardware accelerated WebGL: Hardware accelerated

对于 ubuntu n00b，任何指导都将不胜感激。

Answer 1

我遇到过同样的问题。升级英特尔显卡驱动程序解决了这个问题（除其他外）：

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt-get update
sudo apt-get upgrade

然后重新启动。

你可以在我的博客上阅读详细的解释。
