Linux 用yocto启动Raspberry Pi 3上的Electron应用程序
我用X11构建了一个图像,使用yocto制作了一个树莓皮3和一个触摸屏。我可以通过在串行会话中手动运行命令来启动使用Electron(chromium)构建的应用程序:Linux 用yocto启动Raspberry Pi 3上的Electron应用程序,linux,raspberry-pi3,x11,yocto,Linux,Raspberry Pi3,X11,Yocto,我用X11构建了一个图像,使用yocto制作了一个树莓皮3和一个触摸屏。我可以通过在串行会话中手动运行命令来启动使用Electron(chromium)构建的应用程序: export DISPLAY=:0 /usr/lib/node/electron/dist/electron --no-sandbox /home/root/app 我想使用init.d脚本在启动时自动执行,但我希望使用正确的方法。我试着用上面的命令在我的用户目录中创建一个.Xsession文件,但它不起作用,我不知道是否可以

我想使用init.d脚本在启动时自动执行,但我希望使用正确的方法。我试着用上面的命令在我的用户目录中创建一个.Xsession
文件,但它不起作用,我不知道是否可以获得所发生事件的日志
据介绍,X11启动时有很多步骤。目前,我只看到一个终端(我猜是从火柴盒中看到的)和一个鼠标光标
使用系统启动应用程序的“标准”方式是什么?有没有办法移除触摸屏上的光标

读取CMDLINE
定义完整X会话的正确方法取决于会话管理器:在Yocto上,通常是火柴盒会话或迷你X会话。根据您的描述,我猜您使用的是mini-x-session(如果找不到会话文件,则会启动终端和窗口管理器)
引述:
因此,添加/etc/mini_x/会话脚本应该是可行的
顺便说一句,在会话文件中,您可能还需要启动一个窗口管理器(没有它,X可以做一些奇怪的事情):
我没有
/etc/mini_x
目录。我将/etc
目录中可能最相关的文件的内容添加到我的问题中。如果您使用mini-x-session,您只需创建目录和文件…我创建了一个新的.Xsession
文件,而不是/bin/bash
我已经写了/bin/sh
一开始就可以了!谢谢
