What is xsession-errors?
提问by Err
So I was looking into why a program was getting rid of my background, and the author of the program said to post .xsession-errors and many people did. Then my next question was: What is .xsession-errors? A google search reveals many results but nothing explaining what it is.
所以我正在研究为什么一个程序要摆脱我的背景，程序的作者说要发布 .xsession-errors 并且很多人都这样做了。然后我的下一个问题是：什么是 .xsession-errors？谷歌搜索显示了许多结果，但没有解释它是什么。
What I know so far:
到目前为止我所知道的：
- It's some kind of error log. I can't figure out what it's related too (ubuntu itself? programs?)
- I have one and it seems like all Ubuntu systems have it, though I cannot verify.
- 这是某种错误日志。我也无法弄清楚它的相关性（ubuntu 本身？程序？）
- 我有一个，似乎所有 Ubuntu 系统都有，但我无法验证。

It's the error log produced by your X windows system (which the Ubuntu GUI is built on top of).
它是由您的 X windows 系统生成的错误日志（Ubuntu GUI 建立在该系统之上）。
Basically it's quite a low level error log for X11.
基本上它是 X11 的相当低级别的错误日志。

Linux graphical interfaces (such as GNOME) provide a way to run applications by clicking on icons instead of running them manually on the command-line. However, by doing so, output from the command-line is lost - especially the error output (STDERR).
Linux 图形界面（例如 GNOME）提供了一种通过单击图标而不是在命令行上手动运行应用程序来运行应用程序的方法。但是，这样做会丢失命令行的输出——尤其是错误输出 (STDERR)。
To deal with this, some display managers (such as GDM) pipe the error output to ~/.xsession-errors, which can then be used for debugging purposes. Note that since all applications launched this way dump to the same log, it can get quite large and difficult to find specific messages.
为了解决这个问题，一些显示管理器（例如 GDM）将错误输出通过管道传输到 ~/.xsession-errors，然后可以用于调试目的。请注意，由于以这种方式启动的所有应用程序都转储到同一日志，因此查找特定消息可能会变得非常大且难以找到。
