触控板和跟踪点无法在Lenovo Thinkpad上运行

Question

我有一台ThinkPad W510因为几个月我已经安装了Debian 9。 在开始时触摸板和跟踪点工作正常。有时不行，但重新启动解决了问题。

几天以来，它停止了工作。我使用外部鼠标工作正常。

我认为这些线可能会给你一些有用的信息（虽然我不明白它们的真正含义）

Answer 1

也许是愚蠢的，但你确定你没有通过Fn + F8停用它吗？

根据bugreport添加

Section "InputClass" Identifier "touchpad catchall" Driver "libinput" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" EndSection

进入"/etc/X11/xorg.conf"也可以提供帮助。
