希望有人能帮我解决这个问题。我有一台联想 Ideapad Z510，配有 ALPS 触摸板。操作系统 = Kubuntu 14.04（同时还有 Windows 8.1）
触摸板被检测为 PS/2 鼠标。使用本指南https://askubuntu.com/a/417518/262262，并进行了一些小修改，我设法让它工作了，多点触控也正常工作了。但重启后，所有设置都恢复到了 psmouse-dkms-alpsv7 修改之前的状态。
可以使更改永久生效吗？
更改前：
触摸板被检测为 PS/2 鼠标：
chp@chp-Lenovo-IdeaPad-Z510-kubuntu:~$ xinput list

⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=13 [slave pointer (2)]

dmesg 写道：
chp@chp-Lenovo-IdeaPad-Z510-kubuntu:~$ dmesg | grep -i alps
[ 1.457466] psmouse serio1: alps: Unknown ALPS touchpad: E7=73 03 0a, EC=88 b6 06
变化：
我开始按照指南（https://askubuntu.com/a/417518/262262)，但每次我重启电脑时，GIT 文件夹都会被删除。所以我把它移到了 /msp。(chmod 777)
文件=安装.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]}"
文件 = 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，避免了安装时的错误。
结果：
chp@chp-Lenovo-IdeaPad-Z510-kubuntu:/psm/psmouse-dkms-alpsv7$ sudo ./install.sh

答案1
您只需安装一次 DKMS 包，它将被复制到/var/lib/dkms/。所以，/tmp/没问题，而且您真的不应该创建/msp/任何一个，因为它违反了文件系统层次结构指南。
我猜想这psmouse被视为一个关键模块，在 Ubuntu 启动时应该可用，因此最终会出现在初始 ramdisk 中。由于您的新模块替换了现有模块 ( psmouse)，您可以尝试运行sudo update-initramfs -u以将新模块放入 initrd 中。您只需执行一次此操作，因为进一步的内核更新将自动触发此操作。
