Ubuntu 15.04 上的大黄蜂

我有一台装有 Ubuntu 15.04 和 Nvidia 显卡 GT840M 的笔记本电脑。我以如下方式安装了视频驱动程序：

sudo apt-get purge nvidia*
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-340
sudo apt-get install nvidia-settings
sudo nvidia-xconfig

之后我安装了 bumblebee 和 primus

sudo apt-get install bumblebee
sudo apt-get install bbswitch-dkms
sudo apt-get install primus
sudo systemctl enable bumblebeed

我/etc/modules-load.d/modules.conf添加了几行

i915
bbswitch

我/etc/modprobe.d/nouveau.conf添加了一行

blacklist nouveau

几乎一切都运行正常。在 nvidia-settings ( sudo gksu nvidia-settings) 中，我选择了要使用的 CPU Intel (power saving mode)，并且我的独立显卡默认处于关闭状态（正如我所希望的那样，因为我需要在大学使用笔记本电脑，而那里没有很多插座可以给它充电，并且打开显卡会消耗大量电量）。当我启动 PC 并输入时，lspci -v我收到一条消息

03:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 840M] (rev ff) (prog-if ff)
!!! Unknown header type 7f

这表明我的卡已被关闭——现在一切正常。

The problem is当我尝试使用我的卡时，例如，primusrun firefox它会打开，当我停止 Firefox 时，它不会关闭。所以我一直开着，耗电很多。关闭它的唯一方法是

# echo OFF > /proc/acpi/bbswitch

但我不想每次使用它时都这样做。如何才能自动完成？

这个问题只在我开始使用 Ubuntu 15.04 时出现过。在此之前（我使用的是 Ubuntu 14.10），它运行正常。

我发现编辑 /etc/bumblebee/bumblebee.conf 以匹配您安装的驱动程序。您的文件应该看起来像您当前的配置。配置完成后，它将在使用命令时自动启用并工作primusrun，退出程序后它将关闭。

# 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)

## 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.

# 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

#         bbswitch - new in BB 3, recommended if available
#       switcheroo - vga_switcheroo method, use at your own risk

我不知道如何“自动”执行此操作，但您可以尝试将 shellscript 放在桌面上，然后在每次关闭正在使用的程序时运行它。这不一定是您想要的，但至少是一种临时的、不太繁琐的解决方案。
