50-synaptics.config 文件中的更改无效。它们被覆盖了吗？

对文件的更改50-synaptics.config没有效果。想更改分辨率。我已添加

Option "VertResolution" "20"
Option "HorizResolution" "20"

请查看日志文件。也许有人能帮我找到问题所在。/var/log/xorg.0.log文件中显示了更改，标记为-->。

它们被什么覆盖了？

你运行的是哪个版本的 Ubuntu？过去几个 Ubuntu 版本已经evdev使用 Wayland取代了 Xorg libinput。

因此，您可能需要遵循以下建议https://askubuntu.com/a/864746/32664。该建议建议您将触摸板配置编辑为/usr/share/X11/xorg.conf.d/90-libinput.conf。

笔记：该链接提供的解决方案适用于 16.04。在我自己的机器上，我运行的是 Ubuntu GNOME 17.04，并且相同的 conf 文件名为/usr/share/X11/xorg.conf.d/40-libinput.conf。
