我知道这看起来很容易解决，但我向你发誓我已经尝试了所有方法。问题是：我正常打字，触摸板突然停止工作。
我切换到 Win10 以查看是否是硬件问题，但它运行良好。
我这样做是为了验证它是否被识别并且它是：
xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ 2.4G Mouse id=9 [slave pointer (2)]
⎜ ↳ Synaptics TM3242-001 id=11 [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)]
↳ XiaoMi USB 2.0 Webcam: XiaoMi U id=10 [slave keyboard (3)]
↳ Intel HID events id=12 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
然后我就这么做了
xinput enable 11
但它并没有起到什么作用，仍然不起作用。
然后我就这么做了
sudo apt-get purge xserver-xorg-input-synaptics
然后重新安装。还是没有结果。
好吧，我想，让我在网上查一下。我找到了一些帖子，并尝试从 synaptics 切换到 libinput，但结果是我没有识别触摸板的驱动程序，它没有出现在 xinput 列表中。
所以我想可能是因为 /etc/X11/ 中没有 Xorg.conf.d，而只有 /usr/share/X11/Xorg.conf.d，所以我复制了 /etc/X11/ 中的文件夹。它什么也没做。
顺便说一下，文件夹是：
(base) fecke@MiFecke:/usr/share/X11/xorg.conf.d$ ls
10-amdgpu.conf 10-radeon.conf 51-synaptics-quirks.conf 70-wacom.conf
10-quirks.conf 40-libinput.conf 70-synaptics.conf
我确实改变了两者之间的顺序，但并没有解决问题。
