我该如何解决这个问题？

答案1

我知道这是一个老问题，但它今天仍然有意义。

我有同样的问题联想 Thinkpad X240，Ubuntu 20.04

我的解决方案：-

sudo nano /lib/systemd/system-sleep/rmi-driver

添加以下内容：-

#!/bin/sh

case $1 in
  post)
    rmmod rmi_core
    rmmod rmi_smbus
    modprobe rmi_core
    modprobe rmi_smbus
    ;;
esac

设置可执行文件：-

sudo chmod +x /lib/systemd/system-sleep/rmi-driver

唤醒后触摸板将会工作:)
