ALPS触摸板被检测为PS / 2，用psmouse-dkms-alpsv7校正，但重启后重置
希望有人可以帮助我解决这个问题。 我有一台带有ALPS触摸板的联想Ideapad Z510。 OS = Kubuntu 14.04（Windows 8.1及其旁边）
触摸板被检测为PS / 2鼠标。 使用本指南https://askubuntu.com/a/417518/262262 ，以及一些小的编辑，管理我让它工作，多点触控工作正常。 但重新启动后，所有设置都恢复了，就像在psmouse-dkms-alpsv7修改之前一样。
是否有可能使更改成为永久性的？
更改前：

变化：
我开始按照指南（ https://askubuntu.com/a/417518/262262 ），但每次重新启动PC时，GIT文件夹都被删除了。 所以我把它移到了/ msp上。 （chmod 777）
file = install.sh
#!/bin/bash # changed from: #!/bin/bash #old line: MDIR="/usr/lib/modules/$(uname -r)" MDIR="/lib/modules/$(uname -r)" #old line: NEWMDIR="$MDIR/${DEST_MODULE_LOCATION[0]}" NEWMDIR="$MDIR${DEST_MODULE_LOCATION[0]}"
file = dkms.conf
#old line: DEST_MODULE_LOCATION[0]="/updates" DEST_MODULE_LOCATION[0]="/updates/dkms"
然后安装它。 上述文件中的修改可防止安装中的错误。
结果：

您只需要安装一次DKMS包，它就会被复制到/var/lib/dkms/ 。 所以， /tmp/很好，你真的不应该创建/msp/ ，因为它违反了Filesystem Hierarchy指南。
我的猜测是psmouse被认为是Ubuntu启动时应该可用的关键模块，因此最终会出现在最初的ramdisk中。 当您的新模块替换现有模块（ psmouse ）时，您可以尝试运行sudo update-initramfs -u以在initrd中获取新模块。 您只需执行此操作一次，因为进一步的内核更新将自动触发此操作。
试试这个：
按照此步骤操作，您将使其正常工作：

然后在终端中执行以下行：
sudo update-initramfs -u
