从内核 3.13.0-29 升级后，我的 synaptics 驱动程序似乎停止了工作。基本触摸板功能仍然有效（包括移动光标和单击），但没有右键单击或中键单击模拟，滚动也不起作用。
synclient -l出现错误：
Couldn't find synaptics properties. No synaptics driver loaded?

所以一切看起来都很正常。另一方面，cat /var/log/Xorg.0.log | grep syna什么也没有给出，但却cat /var/log/Xorg.0.log | grep Syn给出了合理的输出：

我尝试添加条目/etc/X11/xorg.conf，但没有成功。当我使用内核 3.13.0-29 启动时，一切正常。使用任何较新的内核 - 都会出现问题。有什么想法可以修复/调试它吗？
干杯！
