I think its simpler than that. Just set "show on" to "All displays" in the Dock settings on Ubuntu 17.10:

You might try enabling the "multi-monitors-add-on".

Follow the directions given here: <a href="https://www.maketecheasier.com/extend-gnome-3-panel-dual-monitors/" rel="noreferrer">https://www.maketecheasier.com/extend-gnome-3-panel-dual-monitors/</a>,

Reproduced Here for convenience:

<pre><code>git clone https://github.com/spin83/multi-monitors-add-on.git
cd multi-monitors-add-on
cp -r multi-monitors-add-on@spin83 ~/.local/share/gnome-shell/extensions
</code></pre>

Relaunch Gnome Shell by typing "Alt+F2", then typing "r" and pressing enter

Make sure you have gnome-tweak-tool

<pre><code>sudo apt install gnome-tweak-tool
</code></pre>

Then open "tweaks" (gnome-tweak-tool), click on the "extensions", and then enable "Multi monitors add-on"

NB this Also works for Ubuntu 18.04...

blocks|key|1583716|text|我也有同样的问题。到目前为止，我能够在每个屏幕上启用发射器。要做到这一点，您需要转到“设置”(+Settings+)+->端口，并为“显示”设置选择“所有显示”。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|entityMap^0^^$0|@$1|2|3|4|5|6|7|C|8|@]|9|@]|A|$]]]|B|$]]

I have the same problem. 
So far I was able to enable the launcher on every screen.
To do that you need to go to Settings -> Dock and pick "All displays" for "Show on" setting.

Install the Gnome Tweak Tool:

<pre><code>sudo apt install gnome-tweak-tool
</code></pre>

Then launch it

<pre><code>gnome-tweak-tool
</code></pre>

Or get to it by searching for "tweak" in the "Show Applications" area.

Bottom left will be a "workspaces" tab where you can tweak your workspaces. I found what I was looking for there.

I am not entirely sure if what I will suggest is helpful for the very specific question, but I hope it is helpful to other users.

After upgrading some pcs from Ubuntu Gnome 17.04 to Ubuntu 17.10 with dual monitors, it occurred to me that the monitor order and the primary monitor gets changed from the first monitor to the second.

This configuration can be found in the new Ubuntu in Settings, Devices, Displays:

<a href="https://i.stack.imgur.com/OweKL.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/OweKL.png" alt="Ubuntu 17.10 Monitor settings"></a>

You can drag-drop to reorder the displays, and there is a small area below labelled 'Primary Display' which is not very obvious that is clickable.

blocks|key|1583836|text|您是否尝试过将辅助显示器设置为您的主显示器？默认情况下，顶部面板仅显示在Gnome+3中的主显示器上。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1583837|不幸的是，在我看来，Gnome+3中的多监视器支持并不是真正完善的。希望现在Ubuntu正在使用它，事情会变得更好。|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|E|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|F|8|@]|9|@]|A|$]]]|D|$]]

Have you tried setting the secondary display as your main one? The top panel only shows on the main display by default in Gnome 3.

Unfortunately multi monitor support in Gnome 3 is not really polished in my opinion. Hopefully things will get better now that Ubuntu is using it.

Installed Ubuntu 17.10 today, menubar, launcher and the bar which indicates time/date/network connection status are missing.

I am using the secondary display and connecting the laptop to the secondary. Even without the secondary display, the top bar on the screen and launcher are missing. When secondary is enabled and laptop display is disabled,there is no menu bar, launcher and bar at the screen top are also missing.

In Ubuntu 17.04 if we disable built-in-display and enable secondary display it works fine. How can I fix it in Ubuntu 17.10?

今天安装了Ubuntu17.10，缺少了指示时间/日期/网络连接状态的菜单、发射器和条。我正在使用辅助显示器，并将笔记本电脑连接到辅助显示器上。即使没有二次显示，屏幕上的顶部栏和发射器也会丢失。当启用辅助设备和禁用膝上型计算机显示器时，屏幕顶部也没有菜单栏、发射器和条。在Ubuntu17.04中，如果我们禁用内置显示并启用辅助显示，它可以正常工作。我如何在Ubuntu17.10中修复它？
