Re: Nvidia 9600GT: Xorg process and high CPU usage
I have the same and very irritating problem since my upgrade:
XOrg produces nearly always high CPU (50%+) load of both CPU cores, even if I don't do anything. As a result, the whole desktop becomes very unresponsive. It may take up to 2 seconds before a chosen window is activated, scrolling through a list is close to impossible, etc. Also, the fan is on all the time. However, very sporadically, for about a minute, the system suddenly is fine - everything is smooth and fast.
My personal feeling is that there is a problem with events and interrupts. 3D acceleration per se seems fine.
KDE 4.6.1, KDE 4.6.2, with and without (!) Desktop Effects (Kwin or Compiz)
GeForce 8600M GT
Latest 260 (from .rpm files) and 270 (from .run file, beta) drivers
I tried to install earlier drivers, but that failed with a compile error.
There is only one way to eliminate the problem: Running nouveau with no 3D. But I need 3D for my work, so no option for me. But that tells me that the driver is involved in this issue.
I really don't know anymore what to do. Please help me.
PS: I upgraded these days from openSUSE 11.0 and KDE 3.5.10 with dirver 170.xxx and XGL. This old system worked fine, with the exception that XGL always used 40% of my 4GB. But I could live with that.
