我有一个 BCM5974 触摸板设备，尽管看似配置正确，但 Xorg 却错误地加载了该设备。我有一个简单的 /etc/X11/xorg.conf.d/60-synaptics.conf 文件：
Section "InputClass"
Identifier "TouchPad"
Driver "synaptics"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Option "FingerHigh" "50"
Option "RTCornerButton" "0"
Option "RBCornerButton" "0"
Option "MinSpeed" "0.7"
Option "MaxSpeed" "1.7"
Option "SHMConfig" "on"
Option "TapAndDragGesture" "off"
Option "PalmDetect" "off"
EndSection
我想在 X 开始查看它们实际应用后运行 synclient 时查看这些设置。然而，事实并非如此。
我查看 Xorg.0.log，发现设置已应用，只是被重置。

我从例如看到https://askubuntu.com/questions/26290/50-synaptics-conf-options-not-working双重加载 synaptics 驱动程序可能会导致这种情况。该修复应该包含 MatchDevicePath“/dev/input/event*”，但我已经将其包含在我的 60-synaptics.conf 文件中。但是，我不确定我的问题是否相同（它被双重加载）。
配置该设备以便正确应用设置的正确方法是什么？我知道我可以从 .xinitrc 或其他可执行文件加载它。但这不应该直接从 xorg.conf.d 工作吗？显然，这里存在一些我忽略的错误配置或其他用户错误。
