Acer Aspire One 725 Elantech Touchpad not working

[green0eggs]

Hello All.

I had the same problem. I found Nabarlek's solution worked, but I can't scroll. Furthermore, the 'Mouse and Touchpad' settings: there is no longer a touchpad tab (see attached). Am I missing something?

1. Open the Terminal
2. cd /etc/modprobe.d/
3. gksudo gedit options.conf
4. In the text editor, type: options psmouse proto=imps
5. Save the file and close it.
6. sudo modprobe -r psmouse
7. sudo modprobe psmouse

Any further help'd be appreciated! Cheers.
