触摸屏概率出现:
无法操作
只能在当前程序操作（如桌面，在这种情况下，触摸会透过窗口直接传到桌面)
位置异常（目前就ubuntu20.04的设置应用才出现这个问题）
卡死当前程序（有时是整个界面。类似与触摸事件响应时间特长，重新加载驱动就恢复。并且执行卡死之后的操作）(arch特有)
设备 小米平板2
内核 6.10.0-自定义
内核源码：https://github.com/Qs315490/latte_kernel_6.10
出现问题时执行，这两命令其中一个就能恢复
modprobe -r hid_multitouch;modprobe hid_multitouch
modprobe -r i2c-hid-acpi;modprobe i2c-hid-acpi之前内核会报 i2c_hid_acpi i2c-FTSC1000:00: i2c_hid_get_input: incomplete report (66/12288)
在内核源码 drivers/hid/i2c-hid/i2c-hid-core.c里添加以下内容就不报这个信息了。
