orca 包是什么？它可以被删除吗？

这个orca过程似乎是错误 #1788364，这导致终端和其他一些程序无响应。我必须在每个 Ubuntu 18.04 会话中强制终止此进程。

这个包的用途有点神秘。这是提供的描述apt：

$ apt show orca
[...]
Description: Scriptable screen reader
 A flexible, extensible, and powerful assistive technology that
 provides end-user access to applications and toolkits that support the
 AT-SPI (e.g., the GNOME desktop).
 .
 Orca defines a set of default behaviors (reactions to application events) and
 key bindings (reaction to user key presses). These default behaviors and key
 bindings can be overwritten on a per-application basis. Orca creates a script
 object for each running application, which merges both the default behaviors
 and key bindings, and the application specific ones. Orca provides the
 infrastructure to activate and deactivate scripts, as well as a host of
 services accessible from within the scripts.

软件包.ubuntu对此并无补充。

我不知道这些“默认行为”是什么，DE 和系统在orca进程被终止后完全按照预期工作。那么，可以简单地将其删除吗？或者它会破坏某些东西吗？

以下是输出apt purge -s orca

dkb@dkb:~$ apt purge -s orca
NOTE: This is only a simulation!
      apt needs root privileges for real execution.
      Keep also in mind that locking is deactivated,
      so don't depend on the relevance to the real current situation!

Purg orca [3.28.0-3ubuntu1]
dkb@dkb:~$

因此看起来清除它不会是一个问题。

此外，orca似乎没有在我的系统上运行：

dkb@dkb:~$ ps -aux | grep orca
dkb       1999  0.0  0.0  21536  1044 pts/0    S+   16:09   0:00 grep --color=auto orca
dkb@dkb:~$

我不知道你为什么要运行它并且因此需要终止它。
