Question

我正在尝试运行 xinit chromium-browser some_settings address:port 在 /home/pi/.bashrc 文件中。

它在第一个版本 "Jessie PIXEL" 中的作用是在控制台自动登录后启动时打开 chromium 浏览器并打开页面 address:port。

在新版本的 Jessie PIXEL 中，出现以下错误：

有人知道问题出在哪里吗？

PS 如果您在日志中看到“*”，那是“**”，但这是粗体文本
还有'!!'在日志中是 '#' 但那是粗体

Answer 1

我遇到了同样的问题。我是如何解决这个问题的：

创建名为 teacher 的新用户
授予 pi 拥有的所有组
cp /etc/suders.d/010_pi-nopasswd 并将内部用户名重命名为 teacher
startx 并且有效。

注意：不要运行在 byobu 中启动 x，有些错误。

Answer 2

我找到了解决方案：

我不再使用 .bashrc，我完全转移到 rc.local。

sudo node /home/pi/server/server.js &

xinit /usr/bin/chromium-browser --no-sandbox --window-size=1920,1080 --noerrdialogs --start-fullscreen --start-maximized --disable-notifications --disable-infobars --kiosk --incognito http://localhost:3000 -- -nocursor &

exit 0

这样做是在端口 3000 上运行 node.js 服务器，并在 localhost:3000 上运行 chromium，没有鼠标光标和全尺寸的 chromium 浏览器，大约需要 15-20 秒的时间。

现在正在努力展示它而不是一片空白。仍然没有成功，求助！

编辑：如果 chromium 出现带边框，请使用此：

xinit /usr/bin/chromium-browser --no-sandbox --window-position=0,0 --window-size=1920,1080 --noerrdialogs --disable-notifications --disable-infobars --kiosk --incognito http://localhost:3000 -- -nocursor &

Answer 3

特别是，您想将您的用户添加到 tty 组以解决此特定问题。

gpasswd -a pi tty

pi 是您的用户。
