这适用于在 Lenovo ThinkPad Edge E531 上全新安装的 Ubuntu 20.04、内核 5.4.0-40-generic。
症状：合上盖子会关闭显示屏，但笔记本电脑不会进入睡眠状态。系统冻结。重新打开盖子后，系统完全没有响应（无法通过 Ctrl-Alt-F1 登录，有趣的是断开和连接电源会使系统播放相应的声音，似乎无法进行其他交互）。
我发现sudo modprobe -r rmi_smbus在合上盖子之前运行可以完全解决问题。笔记本电脑正常进入睡眠状态并正常唤醒。当然，触控板没有反应。我必须sudo modprobe rmi_smbus在打开盖子并登录后手动调用。然后触控板再次正常工作。
这是关闭盖子时加载journalctl的结果。rmi_smbus

有什么建议可以尝试吗？我可以手动卸载rmi_smbus module睡眠前的内容，然后再重新加载吗？或者有更优雅的解决方案吗？
答案1
以下是我的快速而粗略的解决方案，尽管我不确定它在系统更新或升级方面效果如何。这个想法是在挂起之前和之后手动卸载并重新加载有问题的内核模块。
- 在终端中以 root 身份登录：
sudo -s - 运行
nano /usr/lib/systemd/system-sleep/pre-suspend-unload-rmi-smbus.sh并输入以下文件内容：
#!/bin/bash if [ "${1}" == "pre" ]; then modprobe -r rmi_smbus elif [ "${1}" == "post" ]; then modprobe rmi_smbus fi
- 使文件可执行：
chmod +x /usr/lib/systemd/system-sleep/pre-suspend-unload-rmi-smbus.sh - 重新启动（但不确定是否需要此步骤）
答案2
我在另一篇文章中看到，rmi_smbus 崩溃与模块的加载顺序有关。对我有用的方法是将 RMI4 构建到内核中，而不是使用模块。
CONFIG_RMI4_CORE=y
睡眠时不再崩溃。这是 Thinkpad T440s。
