I've just bought a new PC which is Acer Aspire V3-551G. First of all, I installed Ubuntu 12.10. However, I couldn't use some features because it's not stable.
Then, I installed 12.04. But my touchpad doesn't work. I found
kcm-touchpad from the repos. Even so, it still doesn't work.
By the way, my touchpad's buttons work and my OS is 64bit.
