将 Linux 中的特定硬件设备列入黑名单

希望有人能帮助我。我的笔记本电脑的触摸设备出现故障。无法在 BIOS 中或通过任何其他方式禁用该设备（除了更换屏幕（成本超过笔记本电脑的价值））。断开连接位于胶合屏幕后面，移除后会破碎。

我想彻底禁用该设备或以某种方式将其硬件地址列入黑名单。理想情况下是内核引导参数、udev 规则或类似的东西。似乎可以识别为

acpi:NTRG0001:PNP0C50 . LNXSYBUS:00/PNP0A08:00/INT33C3:00/NTRG0001:01

它不是 PCI 设备，不会出现在 lspci 中。当然，我还有其他输入设备（触摸板或鼠标），因此不能仅仅阻止所有驱动程序。

我努力了：

  1. 使用 禁用 hid_multitouch 模块echo "blacklist hid_multitouch" > /etc/modprobe.d/hid_multitouch.conf，重新启动（并使用 lsmod 确认它没有加载），但是它随后在后备 hid-generic （而不是 hid_multitouch）下注册，并且仍然在我的屏幕上注册点击。因此这似乎并不能解决我的问题。
  2. 尝试编写一个设置“authorized=0”的 udev 规则（在 /etc/udev/rules.d/80-touchscreen 中），但是我似乎无法弄清楚如何正确地制定它 - 或者 - （更准确地说，因为该参数似乎不存在）我认为它不适用于 HID 设备或其子设备。在 INT33C3 或 i2c-NTRG0001 下的所有这些不同设备中，“授权”不是可写文件。我认为这是错误的路径，因为授权文件不存在。
  3. 尝试从 NTRG 设备中解除 i2c_hid 驱动程序的绑定，echo "i2c-NTRG0001:01" > /sys/bus/i2c/drivers/i2c_hid/unbind这似乎是唯一可行的方法，但它在重新启动后不会持续存在。将其添加到 rc.local 或其他东西似乎有点像黑客。我希望有一种方法可以通过其他方式来完成此任务（尽管这是我的后备方案）。

任何见解如何从内核、udev 或模块加载的角度简单地说“不要对此设备执行任何操作”或始终确保它不绑定到任何驱动程序或简单地阻止来自的所有事件/输入输入设备？

一些摘录（可能是在不同的重新启动模块状态下获取的）可能有助于识别来自 dmesg 的设备（禁用 hid_multitouch）

答案1

您可以使用 禁用它xinput。

执行xinput list并识别您的设备。它将有一个id=NUM.

然后你做：

xinput --disable NUM
