External HDMI display on Ubuntu 16.04, NVIDIA GeForce GTX 960M

Question

External HDMI display on Ubuntu 16.04, NVIDIA GeForce GTX 960M

mar*_*rek 5 nvidia multiple-monitors graphics drivers 16.04

My Dell Inspiron 7566 laptop with Ubuntu 16.04 can't detect external monitor Dell W2709 connected to HDMI port.

I tried:

booting with the display connected,
connecting display after login,
disconnecting and connecting again
System settings/Displays/Detect Displays

Nothing works, the display stays in power save mode, which is it's usual behavior when getting no signal. And the laptop doesn't realize the display is connected to HDMI.

On Windows partition the same display connected with the same HDMI cable connected to the same HDMI port got recognized right away, so the hardware is ok.

Graphic units on board: NVIDIA GeForce GTX 960M + Intel HD Graphics 530. NVIDIA X Server Settings claim both work fine. It doesn't detect any external display though.

I found several suggestions for similar problems, generally falling into two categories: update the kernel or/and try different graphic drivers.

I tried do both. As for kernel, I believe my initial one which came with Ubuntu 16.04 was 4.4.0 or so. I went up trying several versions, including 4.4.8, 4.8.1, 4.8.17 and I ended up on the fresh 4.9.9.

As for graphic drivers, I've bee trying several tutorials, and at some point I ended up with this collection:

I tried all of those drivers, and I believe those are the newest ones NVIDIA offers. Fortunatelly nothing got broken with all those attempts, but unfortunatelly the problem is still not resolved.

I've been trying to use xrandr too, I found that "HDMI-1-1 disconnected". Adding an new resolution 1920x1200 for my external display and trying to force it with arandr ended up with unusable unity on my primary laptop display, fortunatelly it recovered with a reboot.

I will appreciate any suggestions, yet other drivers to try, or maybe other more exotic step-by-step instructions. I got this laptop expecially for my work, and I need to have the external display for it badly. Thanks!

UPDATE: I found a way to get the external monitor DELL 2709W working with my Ubuntu. However peculiar and non-usable it is, it may be a hint to find a real solution:

This method requires another laptop(!) connected to another port of the display. In my case it is a MacBookPro with an adapter, connected to one of DVI ports. This is to keep the display on - it has to actually display anything on screen.
Using Dell monitor controls, I disabled the DDC/CI mode
Using Dell monitor controls, I select the DVI port, so I can see the other system displayedr
I boot up Ubuntu while it is connected with the Dell monitor with HDMI cable, and I log in to unity
Now when I open System Settings/Displays, I can see the secondary display 'Dell Inc. 27"'
Using the Dell monitor controls I switch to HDMI, and voila - I can see the extended desktop
只有当我让 Ubuntu 笔记本电脑入睡一分钟或更糟 - 将其关闭时，扩展桌面消失了，我必须再次执行整个过程才能将其恢复。因此 - 这不是一种工作方式......但也许它是对任何显示/图形硬件专家的提示，我该如何更好地处理它？

这是 xrandr 报告，其中 HDMI 电缆插入笔记本电脑和显示器的 HDMI 端口，并为显示器选择了 HDMI 源（并且显示器处于睡眠状态）：

我在使用 HP Pavillion 笔记本电脑和 GEFORCE GTX 960M 时遇到了完全相同的问题。我在使用电视和投影仪时都遇到了 HDMI 问题。

我最终通过安装最新版本的开源驱动程序（在撰写本文时为 nvidia-390）解决了这个问题。

这些步骤应该可以完成工作：首先清理可能存在的任何最终混乱

apt-get purge nvidia*

Run Code Online (Sandbox Code Playgroud)

然后就可以进行实际安装了

add-apt-repository ppa:graphics-drivers/pp
apt update
apt-get install nvidia-387

原则上重新启动后，您应该获得非空输出

lsmod | grep nvidia

Run Code Online (Sandbox Code Playgroud)

但就我而言，它是空的，这就是它不起作用的原因。Linux 在启动时没有加载相关模块。这是 UEFI 安全启动的错误。显然，安全启动不喜欢开源驱动程序并阻止它们加载。可以通过进入 BIOS 并禁用它来解决此问题（请参阅此处以获取更全面的说明https://askubuntu.com/a/762255）。

如果仍然不起作用，您可以尝试查找以下两个可能的问题：

其他一些驱动程序未列入黑名单，例如 nouveau ( https://askubuntu.com/a/951892 )
该文件/etc/X11/xorg.conf不存在。如果是这样生成它nvidia-xconfig

@marek我有同样的笔记本电脑和同样的问题，我设法解决了它。

老实说，我不能 100% 确定罪魁祸首在哪里，但你可以尝试一些方法

尝试安装最新的 nvidia 36* 驱动程序，在我的安装中它是 367，但您的可能有所不同。您可以从命令行检查我的运行情况

sudo apt-cache search '^nvidia-[:digit]' --names-only

还可以尝试安装nvidia-prime适用于该笔记本电脑所配备的 nvidia 卡 Optimus 系列的驱动程序。

尝试安装最新的 4.4.* 内核，在我的版本上是 4.4.25。

最后，检查您的外接显示器是否支持声音以及 HDMI 电缆上的音频。我的也是这样，我认为这就是给我带来问题的原因。当我将 HDMI 转 HDMI 电缆切换为 HDMI 转 DVI 电缆时，一切开始工作。
