I`ve been using Ubuntu 8.0 for a while, then migrated to win7, now trying to come back to Ubuntu9.1. I've all Nvidia latest 195 installed, graphics CP is working so are True colors, animations. But when I tend to expect good rendering from Beryl, Chrome (chromeextensions.com), it gets jerky. Basic minimize and restore animations work smooth but heavy graphics are way to choppy.

What could be the issue?

This notebook runs on Nvidia 7400 Go (256mb VRAM) and 1.73 Core duo. It used to work great on Ubuntu 8 and Win7 for graphics. Of course, Win7added a new world of graphics capabilities to this machine. I wonder whats wrong with Karmic. Does any1 know?
