我最近在 HP Envy 上安装了 Ubuntu 16.04，但无法使用触摸屏。即使重启后，触摸屏幕也没有反应。我看过几个其他关于此问题的主题，但没有一个能解决我的问题，所以如果某个地方已经有解决方案，我深表歉意。

正如另一篇文章所建议的：
username@username-HP-ENVY-x360-m6-Convertible:~$ sudo rmmod hid_multitouch
[sudo] password for username:
rmmod: ERROR: Module hid_multitouch is not currently loaded
尝试了这个并且如预期的那样没有效果：
xinput set-prop 11 "Device Enabled" 0 && xinput set-prop 11 "Device Enabled" 1
我不太了解 Ubuntu 或驱动程序，所以我真的不知道如何处理这些信息。
答案1
我有同样的问题。HP Envy x360 m6-ar004dx...触摸屏在 Arch Linux（最新主干）和 Ubuntu 16.04 LTS 上都无法工作。据我所知，这个东西有一个 ELAN0732 I2C 触摸屏控制器（/sys/dev/bus/i2c/...）。手动加载（modprobe）hid_multitouch、elants_i2c等，没有取得任何进展。触摸屏在 Windows 下工作正常。不知道接下来该怎么办，除了等待制造商发布驱动程序，或者等待了解触摸屏控制器的人来修复hid_multitouch。
此外，对于拥有此型号笔记本电脑的用户...请执行lsmod | grep -i acer，如果您看到列出的模块，则应卸载并将其列入黑名单。 NetworkManager将再次能够控制您的 WiFi :P
