Just installed Ubuntu 12.04 on a friend's laptop, it's Acer Aspire One 725. Everything is fine except two issues.

The mouse touchpad and Brightness controller. The touchpad is not responding and I tried with Ubuntu 12.10 (Beta 2) Live, but no luck. But the touchpad is working fine on Kubuntu 12.04.

Also when I tried to change the brightness of the screen, it didn't work, but on the screen the level shows changing.

I upgraded the BIOS thinking it may help. But it didn't. Do you know any solution for this?
