我有一台三星 RF711 Intel Core i7 笔记本电脑，运行 Ubuntu 14.04 LTS 64 位。它配有两块显卡 - 一块是英特尔显卡（默认运行），另一块是 Nvidia GeForce GT 540M（我从未在 Ubuntu 上使用它）。
我尝试了 bumblebee 的各种配置，但是当我尝试使用 optirun 时最终都失败了（我在 Xorg 日志中看到过几次“无法分配软件渲染缓存”之类的错误）。
今天早上我又尝试了一次 nvidia-prime。首先，我确保没有安装任何 bumblebee 软件包，然后运行
sudo apt-get purge nvidia*
删除所有已安装的 nvidia 软件包。然后我执行了
sudo dpkg-reconfigure lightdm
确保 lightdm 是默认设置，然后
sudo apt-get install nvidia-331
安装了 331 个驱动程序、nvidia-prime、nvidia 设置等。
重启后，我进入低图形模式。从这里，我设法回到桌面的唯一方法是使用以下命令删除 nvidia 软件包
sudo apt-get purge nvidia*
然后重新启动。当然，这会将笔记本电脑恢复到最初的状态。
以下是 lspci | grep 3D 的输出

答案1
您可以尝试nvidia-prime包，以更好地支持Nvidia Optimus技术。
第一步是使用以下命令清理一下您的系统：
sudo apt-get purge bumblebee* primus libvdpau-va-gl1
我们安装 nvidia 驱动程序和 nvidia-prime：
sudo apt-get install nvidia-331 nvidia-prime mesa-utils
如果您想要高清视频的图形加速，您可以安装：
sudo apt-get install vdpau-va-driver
然后重启系统。然后进入“nvidia-settings”检查 nvidia-prime 部分是否可以切换显卡。
您还可以添加一个小程序，以便于在卡片之间轻松切换：prime-indicator
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install prime-indicator
sudo reboot
答案2
根据您的 xorg.conf，您似乎使用的是 nvidia 而不是 Intel，因此：
“服务器布局”部分
标识符“布局”
屏幕 0“nvidia”
不活跃的“情报”
我发现的所有信息都表明，此配置下的驱动程序已损坏，您最好只使用英特尔。我会联系制造商这里并询问是否可以进行您想要的功能的 BIOS 更新。
答案3
我也遇到了同样的问题。安装 bumblebee 很可能可以解决您的问题。这里
