否 - 错误：无法加载 GPU 驱动程序；无法访问辅助 GPU - 错误：无法加载 GPU 驱动程序

Question

我的笔记本规格：

CPU: Intel Core i5 3230m
RAM: 4gb 1600mhz
I have 2 GPUs:
    1st: Intel HD 4000 
    2nd: Nvidia GT 720m

今天，我安装了 bumblebee 和 Nvidia 331 驱动程序。安装成功，因此笔记本电脑启动时没有黑屏。问题是笔记本电脑无法启动 Nvidia 程序。而且它无法识别 GPU。以下是我所做的：

sudo apt-get install nvidia-331 bumblebee linux-headers-generic
sudo gedit /etc/bumblebee/bumblebee.conf

用以下值替换匹配的关键字：

Driver=nvidia
KernelDriver=nvidia-331
LibraryPath=/usr/lib/nvidia-331:/usr/lib32/nvidia-331
XorgModulePath=/usr/lib/nvidia-331/xorg,/usr/lib/xorg/modules

保存并退出

然后我删除了 304 驱动程序

sudo jockey-text -d kmod:nvidia_304

然后通过运行此程序并按确定来重新配置一些内容。

sudo pam-auth-update --force

已重新启动。

然后我安装了VirtualGL http://sourceforge.net/projects/virtualgl/files/VirtualGL/2.3.3/

sudo dpkg -i virtualgl_2.3.3_amd64.deb

运行 optirun 后，输出如下：

nikola95o@nikola95o-X550VC:~$ optirun -vvv glxgears

如果您需要我提供其他信息，请告诉我。

Answer 1

好的，我们的规格非常相似！您需要删除 Bumblebee 和 304 Nvidia 驱动程序。Bumblebee 无法在我的 Optimus 机器上运行，同样的问题。获取 Prime 指示器。

要删除并清除大黄蜂，请运行终端（如果出现黑屏，请按Ctrl+Alt+F2）并输入：

sudo apt-get remove --purge bumblebee

要安装 Prime，请运行：

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install prime-indicator

它应该可以与 Prime.Indicator 一起使用。如果不行，请使用以下命令清除所有文件：

sudo apt-get remove nvidia* prime-indicator && sudo apt-get autoremove

并从头开始：

sudo apt-get install nvidia-331 prime-indicator

当你让它工作时，安装 mesa-utils，sudo apt-get install mesa-utils它允许我们识别 GPU。从 Prime Indicator 切换到 Intel GPU 并获取英特尔显卡安装程序，在 Dash 中找到安装程序并运行它以使用最新的驱动程序更新您的 Intel 4000。

编辑：安装英特尔软件包后，如果sudo apt-get update“download.01.org”公钥失败，请在终端中运行以下命令：

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A902DDA375E52366

Answer 2

我在 debian 中遇到了这个问题，

Driver= to Driver=nvidia

和

KernelDriver=nvidia to KernelDriver=nvidia-current

然后重新启动 bumblebeed 解决了这个问题。希望这会有所帮助。无论如何，检查你的驱动程序的名称

ls -l /lib/modules/`uname -r`/nvidia/

并尝试将其设置为你的 bumblebee 配置。
