可切换 nvidia GT 540m HDMI 输出问题

我购买了配备 nvidia GT 540m 和内置显卡的 Alienware m11xr3。

uname -r
3.2.0-33-generic-pae

输出如下lspci | grep VGA：

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 GF108 [GeForce GT 540M] (rev ff)

到目前为止一切顺利。Geforce 已被识别，我可以通过 optirun 使用它：

optirun glxspheres 
Polygons in scene: 62464
Visual ID of window: 0x21
Context is Direct
OpenGL Renderer: GeForce GT 540M/PCIe/SSE2


glxspheres 
Polygons in scene: 62464
Visual ID of window: 0x9e
Context is Direct
OpenGL Renderer: Mesa DRI Intel(R) Sandybridge Mobile x86/MMX/SSE2

以下是来自 /etc/bumblebee 的文件

现在有几个问题：

1) 当我关闭在 optirun 中运行的应用程序时，Bumblebee 似乎不会关闭。它仍处于“开启”状态

2) HDMI 输出根本不起作用。这意味着，当我插入 HDMI 电缆时，我真的不能说是否有反应。显然没有显示任何内容。

3) 找不到 cat /etc/X11/xorg.conf！

4) 我也有 DisplayPort 并想过使用它，但还没有适配器。也许用这个就可以了？

老实说，我对 Linux/Ubuntu 还比较陌生。我使用 Ubuntu 大约有半年了，所以我不是专业人士，但我可以毫无问题地完成基本工作并遵循指南。

如果我们能解决这个问题就太好了。有很多 m11xr3 用户都遇到了这个问题，我想让 hdmi/Displayport(?) 工作并非不可能。如果您需要任何其他信息，请告诉我！感谢您的时间和帮助！

好的，我这边有更新。

现在我可以用不太方便的方式使用 hdmi 输出。我做了什么：正如我在上一条评论中所写，我使用 linlap 指南重新安装了 Ubuntu。然后我发现这 二有用的指南。

现在它的工作方式这里。

希望我能用这个解决方案帮助别人，但对我来说，主要问题是，你无法克隆你的桌面，你需要安装另一个桌面环境。有什么想法可以改进脚本以在两个显示器上使用统一吗？

答案1

  1. 您应该提交错误报告。

  2. 摘自大黄蜂维基

    Optimus 笔记本电脑有两个视频芯片：一个集成的 Intel 芯片和一个独立的 nVidia 芯片。如果端口 (DisplayPort / HDMI / VGA) 连接到 Intel 芯片，则无需执行任何特殊操作即可使外接显示器正常工作。

    当端口连接到 nvidia 芯片时，您目前无法将屏幕扩展到显示器上。显示器仍可用作额外屏幕（不运行桌面）或在其上运行完整桌面（Intel LVDS 输出上没有输出，又称“笔记本电脑显示器”）。

    我不知道您使用的是哪种类型的线路。需要禁用电源管理。您可以阅读更多内容

  3. Bumble 不使用普通的 xorg.conf 文件。配置文件是这个（根据您的问题） /etc/bumblebee/xorg.conf.nouveau

因此，最好阅读问题和 wiki从这个 github 项目页面。
