Ubuntu 14.04没有检测到我的独立GPU
我最近购买了一台配备Nvidia GeForce 860m的笔记本电脑，并安装了Ubuntu 14.04。 在我的旧笔记本电脑上，我有12.04，它自动用Nvidia驱动程序填充其他驱动程序。 但在这台计算机上，附加驱动程序中唯一的function就是高通。 所以我手动安装了Nvidia，但是X Server Settings似乎没有检测到任何GPU ……
lspci | grep VGA lspci | grep VGA仅报告我的集成Intel GPU，但是
lspci -v报告很多东西，包括Nvidia GPU：
01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 860M] (rev a2) Subsystem: ASUSTeK Computer Inc. Device 157d Flags: fast devsel, IRQ 16 Memory at ec000000 (32-bit, non-prefetchable) [size=16M] Memory at c0000000 (64-bit, prefetchable) [size=256M] Memory at d0000000 (64-bit, prefetchable) [size=32M] I/O ports at e000 [size=128] Expansion ROM at ed000000 [disabled] [size=512K] Capabilities: access denied
不知道这是什么意思。 不确定是否应该说“拒绝访问”……
我需要我的GPU来做CUDA和OpenGL编程。 我还能做些什么来弄清楚为什么这不起作用？
编辑：每个请求，xorg.conf的内容：

它是通过安装nVidia驱动程序版本331修复的：
sudo apt-get purge nvidia* sudo apt-get install nvidia-331-updates-dev
然后根据这里的说明安装大黄蜂：
sudo apt-get install bumblebee bumblebee-nvidia primus
重启后，我可以使用’optirun’命令将我的nVidia gpu用于特定程序。 🙂
