本周早些时候安装了 Ubuntu 20.04，但在从挂起状态唤醒后，我仍然无法让触摸板工作。
我可以确认，触摸板在完全关闭后将再次工作（重新启动不起作用）。
奇怪的是，当我尝试重新启动（触摸板不工作）并进入 BIOS，然后启动 ubuntu（根本没有关机）时，触摸板又恢复工作了。
但是在休眠状态下，触摸板在唤醒后可以正常工作，但我确实没有太多时间等待休眠处理时间......它比挂起时间长得多。
在 Windows 中，触摸板工作正常......这似乎与 Linux 驱动程序有关。
我尝试过其他人的建议，例如 触摸板停止工作 20.04 我从 reddit 上找到了其他一些，但是都没有用。
如果我能让触摸板和睡眠模式像休眠模式一样协同工作的话，我将非常感激。
以下是 T480 的一些详细信息：

答案1
我在安装了 kubuntu 22.04 的联想笔记本电脑上遇到了同样的问题。挂起/休眠后，触摸板关闭了。
对我有用的是禁用和启用 xinput；
xinput disable 'SynPS/2 Synaptics TouchPad' && xinput enable 'SynPS/2 Synaptics TouchPad'
（我从 的输出中得到了你的触摸板xinput list）
如果这会重新启动你的触摸板，你可以在脚本中添加命令，让它在睡眠后自动执行；这个答案帮助我让这样的脚本正常工作从 sleep.d 中的脚本执行 xinput
希望这可以帮助！
答案2
以上方法对我不起作用（我有一台 ThinkPad L440）。如果您查看 dmesg，您可能会看到一些 rmi 错误（看起来像是 IRQ 读取的内核错误）。
执行以下操作来修复恢复后的触摸板：
rmmod rmi_smbus && modprobe rmi_smbus
创建 systemctl 服务来自动进行此修复：
[Unit]
Description=Run command on resume
After=suspend.target
[Service]
User=root
Type=simple
ExecStart=/bin/bash -c "rmmod rmi_smbus && modprobe rmi_smbus"
[Install]
WantedBy=suspend.target
