I installed ubuntu 9.04 on my Dell Inspiron 8200 laptop (1.7 GHz, 1GB RAM, NVIDIA GeForce4Go/16 MB). Out of the box it seems reasonably responsive, however I have been unable to successfully install NVIDIA drivers, either from the Jaunty repositories or from NVIDIA directly. In both cases upon rebooting the response is very slow, unusable really. What am I doing wrong?
