双显卡：nvidia和intel集成显卡

起机时默认nvidia显卡关闭，只使用intel集成显卡，有：

sudo lshw -C video *-display description: VGA compatible controller product: 3rd Gen Core processor Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:29 memory:f3000000-f33fffff memory:d0000000-dfffffff ioport:6000(size=64)

使用nvidia显卡看电影：

然后关闭smplayer，再观察显卡：

sudo lshw -C video *-display description: 3D controller product: GF117M [GeForce 610M/710M/810M/820M / GT 620M/625M/630M/720M] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=nvidia latency=0 resources: irq:16 memory:f2000000-f2ffffff memory:e0000000-efffffff memory:f0000000-f1ffffff ioport:5000(size=128) *-display description: VGA compatible controller product: 3rd Gen Core processor Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:29 memory:f3000000-f33fffff memory:d0000000-dfffffff ioport:6000(size=64)

发现nvidia和intel显卡都被识别。请问现在是不是nvidia也在工作，如果是，怎么关闭它呢？

这可能与 poloshiau 提到的双显卡 ‘muxed’ 设计有关。这种情况下，“…独立显卡是接在集成显卡上输出的…”。
这种情况下，独立显卡会被识别为 3D controller，而不是 VGA compatible controller
参考 forum.ubuntu.org.cn/viewtopic.php?f=42&t=476675

具体还是要请 @poloshiao 来讲解

至于 nvidia 是不是在工作，我想还是通过功率来判断
断开电源适配器，运行 powerstat -d 0 监测电池放电功率。一张独立显卡吃掉几瓦功率是正常的
不管怎么样，只要不耗电我们就可以放心了 :slight_smile:

vickycq 已有詳細介紹 相同部份不再重述 只補充說明

  1. muxed
    顯卡 分 muxed 及 muxless
    1-1. muxed : a multiplexer (or mux)
    1-1-1. en.wikipedia.org/wiki/Multiplexer
    1-1-2. zh.wikipedia.org/wiki/%E6%95%B0 … 9%E5%99%A8
    1-1-3. wiki.cchtml.com/index.php/Features#MUXed_Systems
    1-2. muxless : 顧名思意 不是 muxed
    1-2-1. wiki.cchtml.com/index.php/Featur … ss_Systems
    1-3. 最大不同
    muxed 顯卡 可以單獨用來 計算/處理 3D 並且 顯示出來 所以 可以切換
    muxless 顯卡 只用來 計算/處理 3D 再交給 Intel (或 AMD) 集成顯卡 顯示 (猜測 這是 3D controller 名稱的由來) 一般 不必切換

  2. 由於 muxless 顯卡 計算/處理 3D 再交給 Intel (或 AMD) 集成顯卡 顯示 的分工 可以使得 顯卡溫度降低 效能提高 具有 optimus 功能的 nVidia 顯卡 目前 大部分是 這種設計
    2-1. 在 Debian 目前需要安裝第三方軟體 Bumblebee
    2-1-1. wiki.debian.org/Bumblebee
    2-1-2. github.com/Bumblebee-Project/Bu … -and-usage
    2-2. 在 Ubuntu
    2-2-1. 早期版本 跟 Debian 一樣 需要安裝 Bumblebee
    2-2-1-1. wiki.ubuntu.com/Bumblebee
    2-2-1-2. help.ubuntu.com/community/Hybri … IA_Optimus
    2-2-2. 12.04.3 - 12.04.5 / 13.10 / 14.04 及 以後版本
    Ubuntu 自己重編譯的 Linux Kernel 可以支援 HybridGraphics 雙顯卡
    (This enablement work builds upon NVIDIA’s work on PRIME and AMD’s work on PowerXpress.)
    意思是 不需要再安裝 Bumblebee 只要安裝具有支援 PRIME 的閉源驅動 (nVidia) 或 具有支援 PowerXpress 的閉源驅動 (AMD)
    2-2-2-1. wiki.ubuntu.com/X/Config/HybridGraphics

不过问题的核心是 使用 primusrun 后，lshw 为何能检测到 nvidia
这一点还没搞清楚。

另外，例子中“使用 nvidia 显卡看电影”
这里看电影并不需要 3D 渲染，只需要硬件解码
这方面工作 Intel 集显完全可以胜任

powerstat -d 0实测显示：用过primusrun 后，耗电增加了3-4 watt。看来是nvidia开始工作了。

  1. 按poloshiao的介绍，我有了这样的疑问：现在两块显卡都工作了，是不是实际上是nvidia首先做了计算，然后交给intel显卡显示呢？
  2. 现在手动操作的方式关闭nvidia呢？

…恕删
2. 现在手动操作的方式关闭nvidia呢？[/quote]

按理说，bumblebee 会自动关闭独显，这是通过卸载 nvidia-modeset(nvidia, nvidia_uvm) 模块实现的
但最近的 bumblebee 不知为何，常常无法正常卸载 nvidia-modeset(nvidia, nvidia_uvm) 模块，导致独显始终运行。

如果用 bumblebeed --debug 查看输出，可能会看到这样的信息：

242.700519] [INFO]Unloading nvidia driver 242.700603] [DEBUG]Process modprobe started, PID 3109. modprobe: FATAL: Module nvidia not found. 242.701203] [DEBUG]Process with PID 3109 returned code 1 245.706761] [ERROR]Unloading nvidia driver timed out. 245.706801] [DEBUG]Drivers are still loaded, unable to disable card

根据讨论，这是由于最近的 bumblebee 开始使用 modprobe -r 取代了 rmmod，而 nvidia 驱动没有正确设置模块别名，导致卸载失败

临时手动关闭：（这里我没搞清楚究竟是 nvidia 还是 nvidia-modeset, nvidia-uvm，尝试一下）

[code]# modprobe -r nvidia_modeset

tee /proc/acpi/bbswitch <<< OFF[/code]

根据讨论，这个问题已经被修复了
stretch 的 bumblebee 为 3.2.1-10，恰好为修复的版本

参考

bugs.debian.org/cgi-bin/bugreport.cgi?bug=802245

  1. 手动关闭操作没有变化，功耗仍然在15 watt左右，nividia启动前在10 watt左右。
  2. 现bumblebee版本恰为3.2.1-10。

那麽执行 bumblebeed --debug 看是否有如楼上所述的错误信息？
为了获取干净的日志：

  1. 重新启动计算机
  2. 打开一个终端，停止 bumblebee 相关服务，再从该终端手动运行 bumblebeed --debug
  3. 再打开一个终端，使用一次 primusrun
  4. 查看第一个终端中的信息

方便的话可提供 /etc/nvidia/nvidia-modprobe.conf 的内容

重点参考 github.com/Bumblebee-Project/Bumblebee/issues/691

  1. manpages.debian.org/cgi-bin/man. … &locale=en
    primusrun - run an application on a discrete NVIDIA video card
    看看 這個 primusrun 的標的 是否可以說明

[quote]这里看电影并不需要 3D 渲染，只需要硬件解码
这方面工作 Intel 集显完全可以胜任[/quote]

  1. geforce.com/hardware/technol … technology
    Using NVIDIA’s Optimus technology, when the discrete GPU is handling all the rendering duties, the final image output to the display is still handled by the Intel integrated graphics processor (IGP). In effect, the IGP is only being used as a simple display controller, resulting in a seamless, flicker-free experience with no need to reboot.
    在上面的 optimus technology 解說裡
    2-1. 沒有特別說 只渲染 3D
    2-2. Intel 顯卡 只用來簡單的顯示

試試看 是通例 還是偶發事件
方法
在未執行 primusrun command 情況下
開機後 5 分鐘 / 10 分鐘 / … 每隔一段時間
把下面指令 複製 貼進終端機 執行

  1. sudo lspci -knn
  2. sudo lshw -numeric -class video
    看看 能否偵測到 nvidia 显卡及驅動

我在安装nvidia驱动这一步出了问题，现象是电脑休眠唤醒后外部显示器屏幕变形。机器是联想Thinkpad P50，i7-6700HQ CPU， NVidia Quadro M1000M显卡，尝试安装了nvidia-361和364.使用了4.6.0-rc5内核，GNOME 3.20桌面环境。不知有没有大侠可以祝我一臂之力，以便完成Bumblebee的安装？谢谢。

[quote=“i2000s”]现象是电脑休眠唤醒后外部显示器屏幕变形。尝试安装了nvidia-361和364.使用了4.6.0-rc5内核，GNOME 3.20桌面环境。不知有没有大侠可以祝我一臂之力，以便完成Bumblebee的安装？谢谢。qxd@qxd-QC5-Ubuntu
[/quote]

操作系统是 Ubuntu 还是 Debian？
如果是 Ubuntu，可能无需安装 Bumblebee。

外接显示器变形 与安装 Bumblebee 的关系是？

13

操作系统是Ubuntu 16.04，或许你说的是对的，可以不安装Bumblebee。我已经卸载Bumblebee，而且删除了相关的ppa源。但是问题依旧。这个问题应该跟Bumblebee无关。不确定nouveau是否影响了显示器的效果。我不安装nvidia显卡驱动，使用默认的nouveau也是这个问题，而且上面的命令行结果显示nvidia显卡驱动没有用在外部显示器上，不知道这个是不是根本原因。不知如何修复。。。

14

I sorted it out, I think…

我原来安装的nvidia驱动跟4.6内核不兼容（已上报给nvidia开发者，见devtalk.nvidia.com/default/topic/926824/linux/364-1-2-5-won-t-compile-against-latest-kernel-git-tree-patches-for-4-6-0-rc3-included-/），回到4.4内核后使用基本正常。应该ubuntu下不用装Bumblebee就可以开Optimus。正使用nvidia-prime来控制显卡的使用。谢谢！

感谢楼主分享，多显示器的使用经验是很有价值的。 :smiley:

网上抄的，已试过，可行

第一步：安装我们的主角Bumblebee(大黄蜂)
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia
sudo reboot

ps: Bumblebee3 已经非常完善，把所有的东西都配置好了

第二步：查看显卡工作状态
lspci |grep VGA

结果如下：
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 GF108 [GeForce GT 540M] (rev ff)

独显的状态为rev ff 即为关闭状态，OK 大功告成

Bumblebee稳定版已经很久没有更新，可能对最新的电脑不支持。建议有以下两点：

  1. 等待Bumblebee 4.0和bbswitch 1.0版发布。开发组内的信息是他们对kernel 4.7和最新的硬件已经提供稳定支持。若不想等待，可以切换到他们的nightlybuilt channel使用开发版（可能仍有bug）。
  2. 安装稳定版Waylands或者Unity 8、Mir显示环境。这两者替换掉了原来X-windows的显示管理功能，原则上不再需要Bumblebee等显卡管理插件即可对双显卡优化管理。目前的Ubuntu下Gnome 3.20已经对Waylands基本支持。Unity 8和Mir可以使用Ubuntu 16.10及其他Linux的发行版体验。据说目前已经比较稳定。
