Hope someone can help me a little with this problem. I have a Lenovo Ideapad Z510, with a ALPS touchpad. And OS = Kubuntu 14.04 (Windows 8.1 alongside with it)

The touchpad is detected as an PS/2 mouse. Using this guide https://askubuntu.com/a/417518/262262, and some minor edits, managed I to get it to work, and multitouch is working as it should. But after reboot, all settings went back, as it was before the psmouse-dkms-alpsv7 modification.

Is it possible to make the changes permanent?

Before changes:

The touchpad is detected as an PS/2 mouse:

    chp@chp-Lenovo-IdeaPad-Z510-kubuntu:~$ xinput list

The changes:

I started to follow the guide (https://askubuntu.com/a/417518/262262), but every time I restartet the PC, the GIT folder was deleted. So I moved it to /msp instead. (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"

and then installed it. The modifications in the above files, prevented errors under install.

You only need to install the DKMS package once, it will be copied to /var/lib/dkms/. So, /tmp/ was fine, and you really should not create /msp/ either as it violates the Filesystem Hierarchy guidelines.

My guess is that psmouse is considered a crucial module which should be available when Ubuntu boots, and therefore ends up in the initial ramdisk. As your new module replaced an existing module (psmouse), you can try to run the sudo update-initramfs -u to get your new module in the initrd. You only need to do this once as further kernel updates will trigger this automatically.
