在Linux中将特定硬件设备列入黑名单

Question

希望有人能帮我。我有一台笔记本电脑的触控装置出故障了。该设备不能在bios中禁用，也不能以任何其他方式禁用(除了替换成本超过膝上型计算机的屏幕外)。断开是在一个粘合的屏幕后面，当移除时会碎掉。

我想完全禁用这个设备，或者以某种方式列出它的硬件地址。理想情况下，内核引导参数、udev规则或类似的内容。它似乎认为

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

它不是PCI设备，也不会出现在lspci中。自然，我有其他的输入设备(一个触摸屏或鼠标)，因此不能只是阻止所有的驱动程序。

我试过：

1. 禁用带有hid_multitouch的echo "blacklist hid_multitouch" > /etc/modprobe.d/hid_multitouch.conf模块，重新启动(并使用lsmod确认它没有加载)，但是它随后在回退hid下注册-泛型(而不是hid_multitouch)，并且仍然在我的屏幕上注册点击。因此，这似乎不能解决我的问题。
2. 试图编写一个udev规则(在/etc/udev/rues.d/80-触摸屏中)，但是，我似乎不知道如何正确地表述它-或者-(更准确地说，因为这个参数似乎不存在)，我认为它不适用于设备HID或它的子设备。在所有这些INT33C3或i2c-NTRG 0001下的不同设备中，“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. 尝试通过echo "i2c-NTRG0001:01" > /sys/bus/i2c/drivers/i2c_hid/unbind解除NTRG设备上的D8驱动程序的绑定，这似乎是唯一可行的方法，但它在重新启动时并不持久。将这个添加到rc.local或其他东西上似乎有点麻烦。我希望有其他方法来实现这一点(尽管这是我的退路)。

如何从内核、udev或模块加载透视图中简单地说“不要对此设备做任何事情”，或者始终确保它不绑定到任何驱动程序，或者简单地阻止输入设备的所有事件/输入？

一些摘录(可能是在不同的重新启动模块状态下获取的)以帮助从dmesg (禁用hid_multitouch )中识别设备。

Answer 1

您可以使用xinput禁用它。

做一个xinput list并识别你的设备。它将有一个id=NUM。

然后你就会：

xinput --disable NUM
