下午好！
切换操作系统后，联想 Ideapad 3-15ALC6 笔记本触摸板停止工作。
这台笔记本出厂时搭载的是已停产的 Linux 发行版 Satux。到目前为止，触摸板工作正常。后来我换用 Fedora 35，一段时间内它也正常工作，直到我更新系统后，它就完全停止工作了。
在网上研究之后，我尝试用以下技术来解决这个问题：
- Liveboot 较新的 Fedora 发行版 (36) - 负面
- 使用 Ubuntu 22.04 LTS 进行实时启动 - 缺点
- 我最终退出 Fedora 并在其上安装了 Ubuntu。
安装 Ubuntu 后，我发现本文我发现问题可能出在内核上。刚安装完 Ubuntu 后，内核版本是 5.15.0。我做了内核升级到撰写本文时的最新版本为 5.18.6。为此，我按照上述文章中的步骤进行操作，但没有结果。
我也看了类似的过去报告过的问题升级内核解决了问题。但我的情况并非如此，因为我的内核已经是最新的了。
触摸板仍然无法工作。由于这是一台新机器，而且到货时触摸板可以正常工作，所以我认为这是驱动程序支持问题。我联系了联想技术支持，但技术人员说他们必须收回机器并更换触摸板。
我相信这不是问题
我在这里记录我的硬件数据：

我跑了xinput，但看起来我的触摸板没有出现：
