我正在我的 Raspberry Pi 4（4GB RAM 版本）上构建一个自助服务终端应用程序，该应用程序要求 Chromium 作为服务持续空闲。我创建了一个supervisorctl 服务，它可以让它保持活动状态，并让我能够轻松停止、启动、获取状态等。
然而，一段时间后我注意到整个界面冻结了。我在后台运行 Chromium，在前台运行 3 个终端：
tail -f服务日志的终端运行- 终端运行
dmesg -w - 终端运行
htop
我的 Pi 闲置了大约 3 个小时后，果然界面死机了。从 SSH 的角度来看，Pi 可以正常运行，我可以运行命令并做任何我想做的事情，但接口方面发生了严重的崩溃。
查看我打开的终端以获取更多信息，这是我得到的信息：
- 1 号航站楼没有提供任何信息。
- 2 号航站楼提供了一些信息：

- 3 号航站楼似乎显示设备运行正常： 顶部输出
此外，我尝试执行 a sudo service lightdm restart，但终端只是挂起并且没有执行任何操作。请参阅下面的系统日志：

失败后，我做了一个sudo reboot now，但系统从未重新启动。我必须拔掉设备插头然后重新插入。
有人可以帮我弄清楚这里发生了什么事吗？什么可能导致此问题？
作为参考，请参阅下面 os-release 的输出：
NAME="Raspbian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=raspbian
ID_LIKE=debian
答案1
我正在创建一个类似的应用程序，只是通过自动启动脚本 /etc/xdg/lxsession/LXDE-pi/autostart 运行 chrome
@chromium-browser file:///home/pi/fire.html --start-fullscreen
它以非常相似的方式崩溃......
看来我可以建议的唯一修复方法是等待有人发现此错误并发布修复程序并将其发布在这里。我没有足够的声誉来发表评论，否则我只会发表评论。
