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?
