我正在尝试使用Openbox文件/etc/X11/openbox/autostart自动启动一些PyQt程序。 Openbox自动启动成功启动以下示例程序：
import sys
from PyQt4.QtGui import *
application = QApplication(sys.argv)
button = QPushButton("hello world", None)
button.show()
application.exec_()
这是使用自动启动文件中的以下命令启动的：
/usr/bin/python /usr/share/test/test.py
但是，自动启动不会启动更复杂的程序（在本文末尾列出并取自here）。我已经确认使用用户帐户和root帐户成功启动了更复杂的程序，所以我不清楚为什么它不能用Openbox自动启动启动。
它在shell中使用以下命令启动：
/usr/bin/python /usr/share/test/ucom-panel.py
如何通过Openbox启动这个更复杂的程序？
#!/usr/bin/env python

答案 0 :(得分：1)
如果没有openbox的日志输出，它将显示脚本运行时发生的情况，您不太可能得到答案。它可能是路径问题，lib路径问题，权限问题，安全级别问题等。
以下是一些尝试：
将命令的输出记录到文件中，并在运行openbox autostart后检查其中的内容：
your_command >$HOME/openbox_log 2>&1 &
将命令放在脚本中并从autostart调用它而不是使用命令args运行python（这是一个很长的镜头，但值得一试）
答案 1 :(得分：0)
如果您发布autostart会更有用，因此我们可以看一下并寻找解决方案。既然您没有这样做，我将在这里进行猜测。您将命令顺序放置在autostart上，而没有将&放在每个命令的末尾。
因此，当autostart运行/usr/bin/python /usr/share/test/test.py时，它将挂起，等待test.py结束，然后才能运行/usr/bin/python /usr/share/test/ucom-panel.py。我怀疑如果将&添加到每个命令的末尾，它们将按预期工作。
&告诉Shell在后台运行命令并转到下一个命令。
我建议您将/etc/X11/openbox/autostart回滚到之前的状态，而应像这样编辑/home/<username>/.config/openbox/autostart：
#!/bin/sh
/usr/bin/python /usr/share/test/test.py &
/usr/bin/python /usr/share/test/ucom-panel.py &
