我的Elan触控板被检测为鼠标和触摸屏，这两种类型的配置配置文件混合在一起。怎么修呢？

Question

当没有连接外部鼠标时，下面分别是xinput和libinput输出：

$ xinput
⎡ Virtual core pointer                      id=2    [master pointer  (3)]

结果，有时触屏会突然失去做手势和两指滚动的能力，因为鼠标会占据更高的输入优先级。如何避免这种情况？

Answer 1

发现这个方法对我自己起作用的时候，大部分时间都要重新启动死老鼠：

​

我现在的系统是Ubuntu22.04.1LTS(贾米水母)

​

sudo fwupdtool

​

在某些情况下，它不起作用，所以再运行一两次相同的命令。

它只是偶尔不起作用，于是命令关机重新启动，恢复。
