This is an old post. Information here may be out-dated, or the post may reflect opinions or beliefs I no longer share.
Last month, after a lot of searching, I was led to he1per’s repository, which someone from the open-source community was kind enough to point to. Unfortunately, it didn’t work. It was said to work despite errors.
This was unsettling. The code looked a daunting at first, but since I was familiar with C/C++ from my high-school days, I decided to dig deep. It was only fair that I not expect my meal be served to me, and fix it for myself.
After a careful reading and two unexpectedly simple directory path fixes, it would install without any errors, and fixed my touchpad. I was then able to use functionality such as:
- Adjust pointer speed
- Disable while typing
- Two finger scroll
- Natural Scrolling
- Right click with two fingers
Note: Some articles suggest upgrading your kernel, often much ahead than what your Ubuntu installation officially supports. There is absolutely no need to go down that road, as long as you follow the said procedure.
Do you need this module?
dmesg | grep -i alps returns something like the following, you probably need this fix.
psmouse serio1: alps: Unknown ALPS touchpad: E7=73 03 0a, EC=88 b6 06
How do I install it?
I’ve forked the original repository by he1per and fixed the issues resulting in a error-laden install.
To install, run the following in your Terminal:
git clone http://github.com/rusingh/psmouse-dkms-alpsv7
You should now see the following when you open your Mouse and Touchpad settings:
Restart your machine and confirm if this works even after a reboot. You should be good to go! Hope this helped you.
Settings disappearing after a reboot?
If it stops working post a reboot, run
sudo rmmod psmouse && modprobe psmouse in your Terminal and try again. To enable this at each Ubuntu boot, you can edit your
/etc/rc.local file and insert the same command (no
rmmod psmouse && modprobe psmouse
