I keep getting little 10 second lock ups in the game and after a few minutes I crash with this in the log

../../../gk/gkgl/refgl/texmanage.cpp(92) : glGetError() returned 'invalid operation'
../../../gk/gkgl/refgl/shaders.cpp(206): using ARBfp3.0

Anyone seen the same?

Some more info from the errors.log during startup

I am thinking this is the core of the issue, I tried turning down all graphics but it still crashed

This may have fixed it, I need to do more testing. It ran a good 25 minutes without crashing just now but I have to leave.

from : https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.20/+bug/98641

For now, this worked for me:
Download the nVidia drivers from here: http://www.nvidia.com/object/linux_display_ia32_1.0-9755.html
Extract the drivers with the -x switch: sudo sh NVIDIA-Linux-x86-1.0-9755-pkg1.run -x
Copy the module somewhere (hopefully to be removed when they start including it in the package). I used my home directory: cp NVIDIA-Linux-x86-1.0-9755-pkg1/usr/X11R6/lib/modules/libnvidia-wfb.so.1.0.9755 ~/
Now create a link to it from /usr/lib/xorg/modules/: sudo ln /home/aaroncampbell/libnvidia-wfb.so.1.0.9755 /usr/lib/xorg/modules/libwfb.so
That should do it. I also chown'd it to root:root, and chmod'd it to match all the other stuff in that directory.

Hope this helps someone. Once I did that, everything started to work fine. My dual screens, even Beryl runs smoothly (well, as smoothly as Beryl can run).

Ive played two or three 30 minutes sessions with no crashes, at this time I believe the above workaround has fixed this and it is a Nvidia issue.

OK didnt work, not the linux forum is hopping here but it just crashes X after a good 45 minutes or so

Oooookkkk

Changing my monitor to its natural resolution seems to have fixed the crashes, I still get annoying 10 second freeze ups but X not crashing makes it much more playable.
