For all those still looking, I have an Acer Aspire v3 771g and this package: psmouse-alps-dst-0.4.tbz , works perfectly, here are installation instructions:
Extract psmouse-alps-dst-0.4 in /usr/src/ with sudo rights. If you have installed the module before, I suggest you to completely remove it before reinstalling with: sudo dkms remove psmouse/alps-dst-0.4 --all (of course, if you have installed another version of the module, change version number accordingly) Then just give those commands in the terminal: sudo dkms build psmouse/alps-dst-0.4 sudo dkms install psmouse/alps-dst-0.4 sudo rmmod psmouse && sudo modprobe -v psmouse After that your touchpad will be hopefully recognized by your machine.
