После успешной работы шмеля на ubuntu 12.04, установив ubuntu 14.04 долго пытал BUMBLEBEE, много гуглил, ставил и сносил новые ядра... пока не наткнулся на
это. Возможно, кому-то пригодится мой вольный перевод. У меня всё получилось.
Для начала, если что-либо из шмеля ставили, удаляем
sudo apt-get purge bumblebee* && rm -r /etc/bumblebee
sudo apt-get purge nvidia-*
sudo apt-get autoremove
Перезагрузка, перезагружать придётся ещё не раз.
Добавляем репозиторий
sudo add-apt-repository ppa:xorg-edgers/ppa
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
Устанавливаем необходимые пакеты
sudo apt-get install nvidia-331 nvidia-settings bumblebee bumblebee-nvidia primus primus-libs primus-libs-ia32 virtualgl virtualgl-libs virtualgl-libs-ia32 linux-headers-generic mesa-utils
Перезагрузка.
Теперь необходимо подправить "конфиги"
sudo gedit /etc/bumblebee/bumblebee.conf
Я просто удалил всё что было и скопировал следующее:
# 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:/usr/lib/primus:/usr/lib32/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
PMMethod=auto
# colon-separated path to the nvidia libraries
LibraryPath=/usr/lib/x86_64-linux-gnu/nvidia:/usr/lib/i386-linux-gnu/nvidia:/usr/lib/nvidia:/usr/lib/nvidia-331
# comma-separated path of the directory containing nvidia_drv.so and the
# default Xorg modules path
XorgModulePath=/usr/lib/nvidia-331,/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
Теперь надо посмотреть BusID дискретки NVIDIA
lspci | egrep 'VGA|3D'
Увидим что-то похожее
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
02:00.0 3D controller: NVIDIA Corporation GK107M [GeForce GT 750M] (rev ff)
Запомним или запишем то, что касается NVIDIA -- 02:00.0
Внимание! У Вас могут быть другие цифры.
Правим ещё два "конфига"
sudo gedit /etc/bumblebee/xorg.conf.nouveau
Section "ServerLayout"
Identifier "Layout0"
Option "AutoAddDevices" "false"
Option "AutoAddGPU" "false"
EndSection
Section "Device"
Identifier "DiscreteNvidia"
Driver "nouveau"
# 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 is needed on Ubuntu 13.04.
BusID "PCI:2:0:0"
EndSection
В строке BusID "PCI должно быть не 02:00.0 , а именно "PCI:2:0:0" (это пример)
то-есть по одной цифре через двоеточие из того что запомнили, записали.
sudo gedit /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:2:0:0"
# 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
Здесь аналогично меняем BusID на свой.
Перезагрузка.
Проверка
lspci -vnnn
Nvidia видна, но не отображает параметры, то-есть дискретка отключена от питания.
glxgears
Крутятся шестерни и ~60fps --работа интегрированной карты
optirun glxgears
Крутятся шестерни и много больше ~fps --работа дискретной карты.
Если всё так - удача!
Извиняюсь, что много букв.
