我正在尝试为我的 Chuwi lapbook air 注入新的活力，但在安装 ubuntu 19.04 后，触摸板不工作了。
我看到有人指出该问题已为人所知，但没有找到任何有关最终解决方案的信息。
在我的情况下，触摸板被计算机检测到，这里新输入：
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ALPS0001:00 0911:5288 Touchpad id=10 [slave pointer (2)]
⎜ ↳ MOSART Semi. 2.4G Wireless Mouse id=8 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Video Bus id=6 [slave keyboard (3)]
↳ Power Button id=7 [slave keyboard (3)]
↳ Lenovo EasyCamera: Lenovo EasyC id=9 [slave keyboard (3)]
↳ Intel HID events id=11 [slave keyboard (3)]
↳ Intel HID 5 button array id=12 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
这就是里面的东西/proc/bus/输入/设备：

我认为我使用 xserver-xorg-input-libinput 作为驱动程序（？），这是xinput list-props'ALPS0001：00 0911：5288 触摸板'：

它有时可以工作几秒钟，如果我使用外接鼠标或者停止使用触摸板超过 5 秒，它就不会重新启动。
有任何想法吗？
