PyQt:如何在Raspberry Pi桌面启动上运行GUI?

经过多次测试,我自己找到了答案。这是我的工作原理。。。

创建自动运行文件:

2.1 LX终端: cd /home/pi/.config/autostart

2.2 LX终端: sudo nano pythonscript.desktop

2.3 pythonscript。桌面:

[Desktop Entry]
Version=1.0
Name=YourName
Comment=Your comment
Exec=/home/pi/pythonscript.py -nograb #-nograb for comboBox on touch Screen
Icon=/usr/share/pixmaps/python.xpm
Path=/home/pi/
Terminal=false
StartupNotify=true
Type=Application
Categories=Utility;Application;

2.4 Ctrl+O、Ctrl+X、, sudo reboot

很高兴知道:

重要的是,您不能只使用脚本的任何路径。脚本必须直接位于 /home/pi/ 目录,因此您可以使用 Exec=/home/pi/pythonscript.py 在自动运行文件(.desktop)中。我还了解到,如果您的脚本加载了例如一个带有PIL的图像,则该图像必须位于其他位置,可能位于您的桌面上,因为它无法从 /主页/pi/ 目录

如果您的GUI有一个组合框,并且您正在使用触摸屏,那么在您触摸该组合框后,该组合框可能会使整个GUI无法使用。使用 Exec=/home/pi/pythonscript.py -nograb 解决此问题。

StartupNotify=true 对于启动GUI脚本很重要。

希望这有帮助,

通过以下链接,您可以创建一个在启动时运行的后台服务 Service method

再加上这一行

service yourdaemon start

英寸/英寸/英寸/英寸。地方的

假设您的服务名为“yourdaemon”

注意:使用根前缀

示例服务文件

#! /bin/sh
### BEGIN INIT INFO
# Provides:          yourdaemon

# Required-Stop:     $remote_fs $syslog

# Default-Stop:      0 1 6

在/etc/init中以“yourdemon”的名称保存它。并使用

chmod +x yourdaemon
