ALPS 触摸板被检测为 PS/2,使用 psmouse-dkms-alpsv7 进行了更正,但在重启后重置

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 pointer                          id=2    [master pointer  (3)]

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。

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。
