我有一台安装了 14.04 版本的 Dell XPS 13 开发版(我第一次在服务器之外认真使用 Linux)和 OEM 视频驱动程序,但是任何需要 3D 加速的东西都无法运行。
lspci | grep VGA
给我:

和lshw -c video
输出

我在 Chrome 中启用了 WebGL,发布于另一个问题我得到了一个误报,认为一切都在正常chrome://gpu

对于 ubuntu 新手来说,任何指导都将非常感激。

我遇到了同样的问题。升级英特尔显卡驱动程序解决了此问题(以及其他问题):
sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt-get update
sudo apt-get upgrade
然后重新启动。
你可以阅读我的博客上有详细的解释。
问候,
