View Full Version : [ubuntu] High CPU usage on Xorg with Nvidia

December 9th, 2008, 05:01 AM
Hi all,

I'm using Ubuntu 8.10 on a Lenovo T61 thinkpad with a dedicated Nvidia graphics card and Intel Core 2 Duo. Whenever I activate the restricted driver, the CPU usage goes up a lot, with one of my two processors at 80-100% all the time. The display also gets sluggish.

When I disable the restricted driver, things improve a lot (35% of CPU usage on each processor and much faster display) but still aren't as fast as they're supposed to be and I no longer get the desktop effects.

What should I do?

thanks in advance
