bumblebee on ubuntu13.04 没检测到图形设备的解决方法[双显卡同样]

情况:

[ERROR]Cannot access secondary GPU - error: [XORG] (EE) No devices detected.

[ERROR]Aborting because fallback start is disabled.

nvidia驱动的情况下:

root@crper-Aspire-5755G:~# lspci | grep VGA

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 630M] (rev ff)

获取到你的独显的BUSID...就是那个01:00.0

接下来修改 vim /etc/bumblebee/xorg.conf.nvidia

Section "ServerLayout"

Identifier "Layout0"

Option "AutoAddDevices" "false"

Option "AutoAddGPU" "false"

EndSection

Section "Device"

Identifier "DiscreteNvidia"

Driver "nvidia"

VendorName "NVIDIA Corporation"

# If the X server does not automatically detect your VGA device,

# you can manually set it here.

# To get the BusID prop, run `lspci | egrep 'VGA|3D'` and input the data

# as you see in the commented example.

# This Setting may be needed in some platforms with more than one

# nvidia card, which may confuse the proprietary driver (e.g.,

# trying to take ownership of the wrong device). Also needed on Ubuntu 13.04.

BusID "PCI:01:00:0"

# Setting ProbeAllGpus to false prevents the new proprietary driver

# instance spawned to try to control the integrated graphics card,

# which is already being managed outside bumblebee.

# This option doesn't hurt and it is required on platforms running

# more than one nvidia graphics card with the proprietary driver.

# (E.g. Macbook Pro pre-2010 with nVidia 9400M + 9600M GT).

# If this option is not set, the new Xorg may blacken the screen and

# render it unusable (unless you have some way to run killall Xorg).

Option "ProbeAllGpus" "false"

Option "NoLogo" "true"

Option "UseEDID" "false"

Option "UseDisplayDevice" "none"

EndSection

把BusID这一行的注释去掉,修改里面的PCI号(你获取到独显BUSID号码),值得注意的是,获取到的ID号最后一位必须为冒号.

也就是PCI:01:00:0

修改bumblebee的主要配置文件

# Configuration file for Bumblebee. Values should **not** be put between quotes

## Server options. Any change made in this section will need a server restart

# to take effect.

[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-specific settings are grouped under [driver-NAME]. The sections are

# parsed if the Driver setting in [bumblebeed] is set to NAME (or if auto-

# detection resolves to NAME).

# PMMethod: method to use for saving power by disabling the nvidia card, valid

# values are: auto - automatically detect which PM method to use

# bbswitch - new in BB 3, recommended if available

# switcheroo - vga_switcheroo method, use at your own risk

# none - disable PM completely

# https://github.com/Bumblebee-Project/Bumblebee/wiki/Comparison-of-PM-methods

## Section with nvidia driver specific options, only parsed if Driver=nvidia

[driver-nvidia]

# Module name to load, defaults to Driver if empty or unset

KernelDriver=nvidia-current

PMMethod=auto

# colon-separated path to the nvidia libraries

LibraryPath=/usr/lib/nvidia-current:/usr/lib32/nvidia-current

# comma-separated path of the directory containing nvidia_drv.so and the

# default Xorg modules path

XorgModulePath=/usr/lib/nvidia-current/xorg,/usr/lib/xorg/modules

XorgConfFile=/etc/bumblebee/xorg.conf.nvidia

## Section with nouveau driver specific options, only parsed if Driver=nouveau

[driver-nouveau]

KernelDriver=nouveau

PMMethod=auto

XorgConfFile=/etc/bumblebee/xorg.conf.nouveau

修改

Driver=nvidia

KernelDriver=nvidia-current

Module=nvidia-current

Module=nvidia
