I'm using Debian (testing) on a laptop. I have installed the Nvidia drivers and I'm using an external monitor connected to my laptop. My desktop environment is Xfce4.

My problem is that Xorg seems to consume too much of the system resources. If I scroll a web page, it takes about 30/40% of the CPU and the Nvidia card runs at the max frequency.

Maybe I have some bad configurations, but I don't known how to check.

What can I do?

Thank.

Not much of a graphics person myself, but I'd imagine any person able to help you would find it useful to know your Xorg versions, nvidia card model and driver versions, and possibly your kernel version. Also, check your Xorg logs (/var/log/Xorg.0.log) and make sure you actually are using the nvidia driver. –  jw013 May 1 '12 at 20:09

Probably a driver bug. If your card works with the free drivers, try them; the proprietary drivers usually have more features (including supporting more recent chips) and more bugs. –  Gilles May 1 '12 at 23:35
