更新：
我尝试了几个发行版，最后安装了Fedora Compiz Mate 桌面。内置键盘工作正常。但运行sudo dnf update安装了一个较新的内核，我遇到了同样的问题。我粗略地检查了一些日志条目，但看起来完全一样。实际解决方法：我手动选择较旧的内核，内置键盘可以正常工作。在 grub 菜单中
- 较新的内核，内置键盘不工作：Fedora（5.7.14-200.fc32x86_64）32（三十二）
- 较旧的内核，内置键盘在职的：Fedora（5.6.6-300.fc32x86_64）32（三十二）
我想遵循@rickhg12hs 的建议
- 降级旧内核
或者
- 找到 grub 将旧内核作为默认内核的方法。
我怎样才能做到这一点？
此外，我很高兴收到任何建议，以防止进一步的内核更新，你觉得怎么样sudo dnf update --exclude=kernel*（发现这里）
期待您的帮助！

你好！我刚接触 Fedora，想请你帮我解决一个键盘问题。
最近我将笔记本电脑从 fedora 31 更新到了 fedora 32。当我尝试在锁屏上输入密码时，我意识到笔记本电脑的内置键盘无法使用。使用外部 USB 键盘登录可以正常工作。[我已经知道我的触摸板由于某种原因坏了]。
GNOME 版本 3.36.3.、Fedora 32、Wayland，最新
我的笔记本电脑：Acer Aspire E5-511-P7AT；Intel® Pentium® CPU N3530 @ 2.16GHz × 4；Intel® HD Graphics (BYT)
更新所有内容sudo dnf update仍未解决问题。
键盘在 BIOS 中工作正常。因此我推测问题可能与有关libinput。终端输出（选择）：

AT Translated Set 2 keyboard似乎是内置键盘。sudo libinput debug-events在终端中运行得到：

按下内置键盘上的任意键均不会做出任何反应libinput debug-events，除了某些 FN 键（事件 4）。
我现在该怎么做才能让这个内置键盘正常工作？我期待您的帮助。
