Is OpenGL working at all? Does glxinfo produce lots of output, with
'direct rendering: Yes' near the top? If not, your're using software
rendering, all is done by the CPU, not the GPU.

That's what I am thinking. I notice here lately that my CPU is being
used a LOT more then it used to when playing videos or something. I
recently changed kernels and nvidia drivers, the kernel upgrade forced
me to upgrade nvidia. It appears to have gotten worse with each
upgrade. This is what I got from these two commands:

It says direct rendering is working but it sure doesn't act like it. I
watched a video a bit ago and although it was a small thing, only took
about 20% of my screen, it used just about all the CPU power. It didn't
do that a few months or so ago. It used to take only 25% or so to do a
full screen video. This is really weird.
I did take the side off my case a hour or so ago. I took my air tank
and blew it out pretty good. I also checked to make sure the fan was
turning on the video card chip. It was spinning fine and I could feel a
little bit of air. It's a small fan so I wasn't expecting a tornado or
anything. Anyway, after blowing it out AND generating a xorg-conf with
nvidia's program, I get this:
r...@smoker / # glxgears
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
2932 frames in 5.0 seconds = 586.390 FPS
1260 frames in 5.7 seconds = 222.873 FPS
2 frames in 7.6 seconds = 0.263 FPS
2 frames in 8.0 seconds = 0.249 FPS
2 frames in 7.6 seconds = 0.264 FPS
2 frames in 7.7 seconds = 0.259 FPS
XIO: fatal IO error 22 (Invalid argument) on X server ":0.0"

r...@smoker / #
Well, if it wasn't bad enough before, it is really bad now. The first
couple were when the window was really small. I adjusted it to full
screen which is where the 0.2 FPS comes in. That used to be about 30 or
so a while back.
This is with the nvidia generated xorg.conf file. I'm going back to my
hand made one. It seems to be a little better.
Any ideas as to why everything says it is working but it isn't?
