我已经安装了 Bumblebee，它可以正确加载 nvidia 驱动程序...我可以在以下位置看到它/proc/drivers：
quux@quux-Ideapad-Z570 ~ $ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86 Kernel Module 319.60 Wed Sep 25 13:58:16 PDT 2013
GCC version: gcc version 4.8.1 (Ubuntu/Linaro 4.8.1-10ubuntu9)
quux@quux-Ideapad-Z570 ~ $
但是驱动程序工作不太好，我尝试过 304、304-updates 和 319-updates：
它提供的 fps 比集成的低得多。glmark2 基准测试工具对 Nvidia 的评分为 59 分，而对集成的 Intel 的评分为 751 分！
当我运行时，optirun nvidia-settings它说You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just runnvidia-xconfig as root), and restart the X server.。Bumblebee 配置：
[bumblebeed]
# The secondary Xorg server DISPLAY number
VirtualDisplay=:8
# Should the unused Xorg server be kept running? Set this to true if waiting
# for X to be ready is too long and don't need power management at all.
KeepUnusedXServer=false
# The name of the Bumbleblee server group name (GID name)
ServerGroup=bumblebee
# Card power state at exit. Set to false if the card shoud be ON when Bumblebee
# server exits.
TurnCardOffAtExit=false
# The default behavior of '-f' option on optirun. If set to "true", '-f' will
# be ignored.
NoEcoModeOverride=false
# The Driver used by Bumblebee server. If this value is not set (or empty),
# auto-detection is performed. The available drivers are nvidia and nouveau
# (See also the driver-specific sections below)
Driver=nvidia
# Directory with a dummy config file to pass as a -configdir to secondary X
XorgConfDir=/etc/bumblebee/xorg.conf.d
## Client options. Will take effect on the next optirun executed.
[optirun]
# Acceleration/ rendering bridge, possible values are auto, virtualgl and
# primus.
Bridge=auto
# The method used for VirtualGL to transport frames between X servers.
# Possible values are proxy, jpeg, rgb, xv and yuv.
VGLTransport=proxy
# List of paths which are searched for the primus libGL.so.1 when using
# the primus bridge
PrimusLibraryPath=/usr/lib/x86_64-linux-gnu/primus:/usr/lib/i386-linux-gnu/primus
# Should the program run under optirun even if Bumblebee server or nvidia card
# is not available?
AllowFallbackToIGC=false
[driver-nvidia]
# Module name to load, defaults to Driver if empty or unset
KernelDriver=nvidia-319-updates
PMMethod=auto
# colon-separated path to the nvidia libraries
LibraryPath=/usr/lib/nvidia-319-updates:/usr/lib32/nvidia-319-updates
# comma-separated path of the directory containing nvidia_drv.so and the
# default Xorg modules path
XorgModulePath=/usr/lib/nvidia-319-updates/xorg,/usr/lib/xorg/modules
#XorgConfFile=/etc/bumblebee/xorg.conf.nvidia
XorgConfFile=/etc/X11/xorg.conf
正如你在配置中看到的，我甚至尝试使用由nvidia-xconfigBumblebee 生成的 xorg.conf 而不是 xorg.conf.nvidia，结果是一样的。

帮我运行 nvidia-settings

这个问题很久以前就被问过了，但这对我有用：optirun nvidia-settings -c :8
