我有一台联想 z510，它有一个 ALPS v7 触摸板。在新安装 xubuntu 14.04 后，我使用了此修复才能让它工作。现在，在最新的内核更新之后，它不再被识别了。

我仍在运行 xubuntu 14.04，当前内核为 3.16.0-60-generic x86_64
编辑：嗯，看起来很奇怪

我建议删除所有自定义软件包并升级内核。运行：
sudo dkms remove psmouse/alps-1.3 --all
sudo dkms remove psmouse-dkms-alpsv7/1.1 --all
sudo apt-get install linux-generic-lts-wily
重启。
