Execute this command first:

<pre><code>$ sudo xhost +
</code></pre>

Then run the command you want as the other user:

<pre><code>$ sudo -i -u username
$ command you want to run
</code></pre>

When you are done:

<pre><code>$ sudo xhost -
</code></pre>

blocks|key|1290565|text|您可能需要告诉您的X服务器接受来自其他用户的连接，而不是拥有服务器实例的用户(您)。查看xhost命令。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1290566|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You probably need to tell your X server to accept connections from another user than the one owning the server instance (you). Look into the xhost command.

Most solutions provided here don't integrate with Wayland and PulseAudio.
I wrote <code>ego</code> (Alter Ego) for this use case, it automatically handles <code>xhost</code> and Wayland and PulseAudio socket sharing: <a href="https://github.com/intgr/ego" rel="nofollow noreferrer">https://github.com/intgr/ego</a>
So you just run <code>ego app</code> or <code>ego -u somebody app</code>
If you run into problems, please open an issue on GitHub. I may be the only user of it, so it hasn't gotten much testing yet.
(And I notice that I'm a decade late with this answer, but hopefully it will help somebody :D)

Replace <code>&lt;user&gt;</code> with the username to run the command as, and <code>&lt;command</code>> with the command you want to run. Remember that the program will be run in the <code>&lt;user&gt;</code>s context, but in the current directory.

I have ubuntu + x11 + gnome.

I want to run a graphical application as another user.

However, when I start it from the command line using <code>sudo -u otheruser app</code> I get the error "No protocol specified".

How can I work arround this?

X11: run a gnome app as another user

服务器

Wayland 

GitHub

我有ubuntu + x11 + gnome。我想以另一个用户的身份运行图形应用程序。但是，当我使用sudo -u otheruser app从命令行启动它时，我得到错误消息“没有指定协议”。我该如何解决这个问题呢？
