ThinkPad L14 Ubuntu 20.04下触控板无法恢复启用的问题求助

大家好，之前我把笔记本的触控板禁用了，现在想重新启用它，却怎么也找不到恢复的办法。

我用xinput命令查看了当前的输入设备列表，结果如下：

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Logitech Wireless Mouse MX Master 3       id=15   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Power Button                              id=8    [slave  keyboard (3)]
    ↳ Sleep Button                              id=9    [slave  keyboard (3)]
    ↳ Integrated Camera: Integrated C           id=10   [slave  keyboard (3)]
    ↳ Integrated Camera: Integrated I           id=11   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=12   [slave  keyboard (3)]
    ↳ ThinkPad Extra Buttons                    id=13   [slave  keyboard (3)]
    ↳ USB Camera: USB Camera                    id=14   [slave  keyboard (3)]
    ↳ Logitech Wireless Mouse MX Master 3       id=16   [slave  keyboard (3)]

我尝试执行了这条命令来启用设备：
xinput set-prop 4 "Device Enabled" 1
但完全没有效果...

有没有大佬能帮忙解决这个问题？
