Here we are: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1294027
Hope it's OK.

Now I can describe the workaround, which might be helpful for other users:

1- Downloaded drivers here http://www.dahetral.com/public-download/alps-psmouse-dlkm-for-3-2-and-3-5/view
2- Moved the folder "psmouse-alps-1.3" into "/usr/src/"
3- cd /usr/src
4- sudo dkms build psmouse/alps-1.3
5- sudo dkms install psmouse/alps-1.3
6- sudo rmmod psmouse && sudo modprobe -v psmouse
