Just installed a fresh version of Natty. My ubuntu worked during install, but not after it boots up after that.
I had this issue with Meerkat (on this same machine) as well. It worked during install and a few times after it. I have my suspicions that an update to Xorg was the culprit. I used this solution, which left me with a touchpad that was detected as a generic mouse, and therefore provided no scrolling options.
This time around, I tried this solution where I modified a line in /etc/default/grub/.
I've edited the line
I rebooted and the touchpad worked work, once... Even configured my circular scrolling. After another restart, I was back to square one. Any ideas?
