嘿，刚刚安装了全新的 Ubuntu（在戴尔 Inspiron 7415 2-in-1 上），除了触摸板之外，其他一切都运行正常。触摸板似乎只有在我完全重启笔记本电脑后才能正常工作，但合上盖子（挂起）后，触摸板就会失去手势，还会随机自行点击。
我看到一些其他帖子可能会有用（xinput 列表）：
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ xwayland-pointer:15 id=6 [slave pointer (2)]

⎣ Virtual core keyboard id=3 [master keyboard (2)]

暂停的 dmesg：
