我有一个奇怪的问题，我发现与我类似的问题并不完全相同。目前我的工作台上是一台联想 Twist 型号 334776U。我使用 Xubuntu 20.04 的 clonezilla 映像对 2in1 进行了映像。最初，触摸板和 ptr-stick 不起作用。无线有时会起作用（如果我没记错的话，它会断开连接）。但是，通过一些“谷歌搜索”（我忘记了链接），有人提到这个问题已在内核 5.19 中得到解决。我去安装了该内核（使用 Ubuntu 主线内核应用程序），但没有列出内核的进一步 5 系列版本。因此，我安装了 6.0.5 版本，启动到该内核并运行更新。现在，当我启动 6+ 内核时会加载。触摸板和 ptr 棒可能会或可能不会工作，但无线肯定不起作用。我目前不在机器附近。它在工作，我们周末不营业。下面，我从这台机器收集了数据：

如果您已经读到这里，感谢您抽出时间。目前，如果可能的话，我想让无线功能正常工作。触摸板和 PTR 摇杆当然很重要，但要一步一步来。
问候
我可以得到 BUMP 吗？
