I don't know if I have a problem with graphics card, driver or X.org, but I know there is a problem I cannot solve on my own, so please, I need help on this one!
When I installed Dapper, I wanted to enable the graphics acceleration that should be possible with my graphics card so I installed NVIDIA driver. I like eyecandy, and I have enabled shadows etc using «Composite» in xorg.conf. Also, from the list of screensavers I selected some that used some fancy OpenGL effects. All these 3D enabled effects seem to work just nice in the beginning; but fail after some time, usually ~30-40 minutes but can be much more and sometimes less.
The symptoms
Screensaver: I have picked a screensaver called «vitenskap» (norwegian) which I think will be named «science» in the english language version. It is a circular magnification glass (or glass ball) that bounces around your screen. That is what it looks like when I start it. After some time the glass ball stops bouncing around on the screen.(as said above, maybe 30 minutes, maybe less maybe more, I don't often sit down to watch my screensaver :P ) Motion is only intermittent, a few frames per minute is all that seems to be managed, most of the time everything just stands still.
On the desktop: I use partial transparency for the windows that don't have focus, and shadows for all the menus and windowframes. As with the screensaver, this seems to work just fine until at some point the rendering goes extremely slow. It is faster than with the screensaver, but still painfully slow. We are talking maybe a frame a second. Sometimes when I select a menu or open a window only the shadow behind is rendered and then have to wait wait wait wait for content and then frame to appear. Even closing all active windows before logging out thereby restarting X is sometimes so slow I am starting to use the less gentle Ctrl-Alt-Backspace keycombination to restart X.
My system information
I have a Point of View NVIDIA 6800GT 256 Mb graphics card, running Kubuntu Dapper Drake 6.06 LTS - Linux 2.6.15-26-386 running KDE 3.5.2, CPU: Intel(R)Pentium(R)4CPU2.80GHz at 2800 MHz (5605 bogomips), , RAM: 2213/2535MB, 107 proc's, 2.17d up.
My xorg.conf file
I have included my xorg.conf file at the base of this post.
What is really the problem and how can I fix that?
I have spent hours reading through miscellaneous posts on nvidia driver topics mostly in this forum but also others. I cannot find a precise description that exactly matches my problem. I have tried some solutions from «related» problems but it appears not to have any effect.
Can someone please help me identify & solve the problem with my 3D graphics?
